Debian on Netgear RN102

Keep us updated though. I've been trying to build a u-boot image for a different armada-370 device (Linkstation LS441DE). I've had some success setting up a crossbuild setup but haven't been able to generate anything useful yet.

I see bodhi, anyway thank you very much for your support.

whitepawn,

If you have specific questions while rebuilding the RN102 stock u-boot from GPL, I'll do my best to answer them.

All,
First i get really pissed off to netgear because they didn't share u-boot source code, since i get mad to netgear i was desoldered 8gb flash and resoldered 128mb and removed SPI flash mod while doing this surgery i realized why i should not download their entire GPL source codes and look each one by one in first place? I couldn't give up easy.

I didn't have much hope but after downloading nearly 30 gigabytes of netgear source code I finally managed to find GPL code for RN102 in ReadyNASOS_V6.6.0_WW_src.zip.When i saw sourcecode i had a big facepalm and get mad to myself because have already soldered stock flash chip to box.

Anyway i get very motivated like candy seen childs and tried to compile stock u-boot without touching anyhing in code first.After reviewing readme files and downloading toolchain spesific for this u-boot i crossed my fingers and holded my breath:

jigsaw@whitepawn:~/u-boot-2011.12-armada370$

It failed in nand image because of dtb file but it doesn't matter now we can deal this later.I can try my u-boot on box with serial anyway since it generated u-boot-a370-2.0-nand-db-uart.bin.
I soldered back 8GB flash and tried my u-boot on box with my xeon machine:

When i saw the todays date on u-boot i had a pretty nasty smile on my face:)
Then i made some online search for flash chip IDs in u-boot.It seems /u-boot-2011.12-armada370/drivers/mtd/nand/nand_ids.c does this ID stuff.I have added this to code:

/* 64 Gigabit */
{"NAND 8GiB 1,8V 8-bit",  0xAE, 8192, LP_OPTIONS},
{"NAND 8GiB 3,3V 8-bit",  0xDE, 8192, LP_OPTIONS},
{"NAND 8GiB 1,8V 16-bit", 0xBE, 8192, LP_OPTIONS16},
{"NAND 8GiB 3,3V 16-bit", 0xCE, 8192, LP_OPTIONS16},

Compiled u-boot and tried again but it seems i have to find another config option in this file.Still investigating the NAND ID i just wanted to share updates with you guys.Will post results if i succeeded.

Btw I have uploaded toolchain and u-boot source code to my dropbox folder if anyone interested.

Cool!

You should tried this kwboot with the original NAND before desolder/solder new NAND :)

Wonderful! Congratulation! This is great news.

To me, the most annoying shortcoming of the stock u-boot is its inability to boot from a memory stick or an SSD attached to the rear connectors, so USB3 and SATA support are on the top of my wish list for a new u-boot implementation. I understand you have support for large SPI eeproms on your wish list.

What else should be aimed for? Eliminating the incompatibility between the u-boot's serial console and the default Linux' serial console physical addresses? Support for separate DTBs? Adding a tftp boot mode to the boot menu?

I imagine the right way to proceed is to extract the ReadyNAS specific patches from the Marvell u-boot version v2011.12, and modify these patches so they can be applied seamlessly to a recent main stream u-boot implementation. What are the candidates for the "recent main stream u-boot implementation"?

Unfortunately booting with USB 3.0 port will probably not easy to achieve with stock u-boot (of course, it depends on how extensive the Netgear patch is, too). But that booting option is not a priority for NAS vendors so usually they don't botther adding code for it.

Bodhi,
Yes you are right but "i also like to live dangerously"
I modified nand_ids.c code to

{"NAND 8GiB 3,3V 8-bit Custom",	0x64, 0, 8192, 0, LP_OPTIONS},

since 0x64 is my nand id and 2c is manufacturer micron flash id according to here but it cannot id correctly.What am i missing?Are there anymore files to patch?
@tme
I think USB 3.0 boot is not possible because i couldn't find any code regarding fresco FL1009 USB 3.0 controller in stock u-boot.Front USB 2.0 is directly hardwired to Armada CPU on the other hand USB 3.0 is wired to fresco contoller then which is wired to cpu via pci interface since my aim is booting whole system on nand (because of usb reset problems i have) so i didn't investigated deeply.I can try to add fresco driver to stock u-boot but as i said i am a hardware guy more then software so i even don't know what i am doing.
Tftp boot is already in stock u-boot i guess.
Regards.

whitepawn,

Look for

./board/mv_ebu/common/mv_hal/nfc/mvNfc.c

Regarding USB 3.0, yes, it is the PCI bus.

In theory, that's an ideal situation. But U-boot has gone through architectural changes a few times. The Marvell u-boot that is used in these NAS is quite old (its software architecture is at least twice removed from the current mainline u-boot).

All,

Could you guys describe how you connect serial console. Where is the header and what is the pinouts?


It is for AkkJaa in this thread:

https://forum.doozan.com/read.php?3,106724,107619#msg-107619

Seems like the RN102 and RN104 have the same board.

Bodhi,
Please see this about serial pinout.TX and RX is enough for console.GND and VCC are not used if AkkJaa uses USB to serial adapter which is self powered by itself in his case.
Also board itself has 4 pinheader internally but i havent tested yet.
I can upload my own connection photos if you are needed.
Regards.

whitepawn,

That's the J7 header, the 2nd UART port. So you have UART0 and UART1.

Maybe. Add GND for reliable communication. But I agree to leave 3.3 V VCC unconnected.

RX of the USB-to-serial adapter should be connected to TX of the box, and vice versa. Trial and error is the easiest approach since it is harmless to get this wrong. Make sure to get GND right every time - getting this wrong may harm the box or adapter.

Tme,
If you are using isolated power bricks or using plugs without earth (which always connects GND) GND must be connected.
If your PC and Nas power brick connects same outlet with earthing you don't need to connect GND because it is connected Via earthing internally so you won't need to connect extra ground.
Regards.

Yes. And it does not hurt to connect GND in either cases and keep it simple for someone is using this the 1st time.

Not for certain module converter like the CP2012. This converter is already crossed. So RXD to RXD and TXD to TXD is the right connection. OTOH, the Prolific PL3xxx must be connected crossed wire.

Bodhi,
I managed to detect 8gb flash with your recommendation:

whitepawn,

Look for

./board/mv_ebu/common/mv_hal/nfc/mvNfc.c

I have edited nand_ids.c

{"NAND 8GiB 3,3V 16-bit Custom",	0x64, 0, 8192, 0, LP_OPTIONS16},

First it complained about 8 bit config which is LP_OPTIONS then i changed it to LP_OPTIONS16 no more complains from u-boot.

And edited mnNfc.c to:

{			/* Micron 64Gb */
	 .tADL = 0,		/* tADL, Address to write data delay */
	 .tCH = 20,		/* tCH, Enable signal hold time */
	 .tCS = 20,		/* tCS, Enable signal setup time */
	 .tWC = 90,		/* tWC, ND_nWE cycle duration */
	 .tWH = 45,		/* tWH, ND_nWE high duration */
	 .tWP = 45,		/* tWP, ND_nWE pulse time */
	 .tRC = 90,		/* tWC, ND_nRE cycle duration */
	 .tRH = 45,		/* tRH, ND_nRE high duration */
	 .tRP = 45,		/* tRP, ND_nRE pulse width */
	 .tR = 0,		/* tR = data transfer from cell to register */
	 .tWHR = 90,		/* tWHR, ND_nWE high to ND_nRE low delay for status read */
	 .tAR = 65,		/* tAR, ND_ALE low to ND_nRE low delay */
	 .tRHW = 32,		/* tRHW, ND_nRE high to ND_nWE low delay */
	 .pgPrBlk = 256,	/* Pages per block - detected */
	 .pgSz = 8192,		/* Page size */
	 .oobSz = 448,		/* Spare size */
	 .blkNum = 4096,	/* Number of blocks/sectors in the flash */
	 .id = 0x642C,		/* Device ID 0xDevice,Vendor */
	 .model = "Micron 64Gb 8bit",
	 .bb_page = 0,		/* Manufacturer Bad block marking page in block */
	 .flags = NFC_CLOCK_UPSCALE_200M
	 },

Now it detects flash as 8192 megabytes.Yes!

Wrong Image Format for bootm command
ERROR: can't get kernel image!
Marvell>>

Then i booted debian to just to see if it works.Attached full log in post.


First of all is it safe to erase all chip with "nand erase.chip" command?If you say yes then i must use "nand scrub.chip" to mark false positive bad blocks right?

Here is my mtd partition plan:
mtd0 is u-boot 1.5megs
mtd1 is u-boot envs 128k
mtd2 is rootfs rest of flash

Is this the right way to do it?I just want to use your kernel and rootfs i don't need stock os anymore.
Is there any tutorial how to partition nand?After partitioning i will make an image of mtd2 size on pc and dd it to box.I don't know if my taughts are true or this is the right way i am just making speculation.
Regards.

Yes. I would do that nand scrub the first time. After that the mtd system will mark the real bad blocks for you.

There are 2 things to do.

1. Define the mtdparts variable, and possibly also 2 other variables if needed

Example (this is my definition for NSA325 box, adjust them to your real definition)

mtdids=nand0=orion_nand
mtdparts=mtdparts=orion_nand:0x100000(uboot),0x80000(uboot_env)
partition=nand0,2

You must keep the u-boot and u-boot envs mtds exactly the way they were in stock.

$ cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00180000 00020000 "u-boot"
mtd1: 00020000 00020000 "u-boot-env"
mtd2: 00600000 00020000 "uImage"
mtd3: 00400000 00020000 "minirootfs"
mtd4: 07400000 00020000 "ubifs"

And the remaining space could be anything you want. Something like this:

setenv mtdparts mtdparts=orion-nand:0x180000@0(u-boot),0x20000@0x180000(u-boot-env),-(rootfs)

And then boot into Debian.

And use nandwrite to populate the first 2 mtds inside Debian (always better to do it in Linux to take advantage of better MTD sysem software).

1. U-boot image can be flashed directly to mtd0 (pay attention to image size and mtd0 size). But still better to pad the rest to fit exactly to mtd0.

2. The easy way to populate the envs mtd is to save it in serial console after the u-boot was flashed and reboot (The harder way is format it as an u-boot image of 128K before flashing).

3. mtd2 UBIFS device needs to be attached before you can create a volume, mount, and then tar the rootfs tarball to it.

Note: mtd2 does not need to be UBIFS, if you just want to populate uImage and uInitrd to boot the USB rootfs. If the goal is to have a real rootfs on NAND then yes, UBIFS is the best option. But this configuration is flexible. There are many alternatives. If you want to real rootfs on USB 3.0 then you need mtd2 and mtd3 to be where the uImage and uInitrd reside.

All 3 steps above need to be filled in (please post questions if you are not sure which commands to use).

========

Food for thought: my rootfs on the Mirabox is on USB 3.0 in the back. My kernel files uImage and uInitrd are on SD card /boot folder. I'm still testing so don't want to flash uImage and uInitrd to MTDs.

Bodhi,
Thank you for your fast reply.
I have scrubbed then erased whole NAND.After scrubbing, my placebo "bad blocks" are gone.I still have some of them but i assume it is normal in such big NAND.Attached log in attachment.

After clearing NAND issues i have set up my envs like below:

It complains about error correction system, how can i fix this?:

T1] nand: WARNING: pxa3xx_nand-0: the ECC used on your system (16b/2048B) is too weak compared to the one required by the NAND chip (40b/1024B)

Checked mtd parts, seems right:

But when i used nandwrite to test if i can write mtd1 it says permission denied:

root@Neutron:/media# nandwrite -p /dev/mtd1 mtd1  
nandwrite: error!: /dev/mtd1
           error 13 (Permission denied)
root@Neutron:/media# flash_eraseall -j /dev/mtd1
flash_eraseall has been replaced by `flash_erase <mtddev> 0 0`; please use it
flash_erase: error!: /dev/mtd1
             error 13 (Permission denied)

Also could you please make dtb for this layout?Or your linux-5.8.5-mvebu-370xp-tld-1-bodhi archive dtb is enough?I needed it to build U-boot nand image, right now i am using uart image as you know:

1. U-boot image can be flashed directly to mtd0 (pay attention to image size and mtd0 size). But still better to pad the rest to fit exactly to mtd0.

I can take my original mtd0 backup fill it with ff and insert new nand uboot code in it then i can dd it (unsafe maybe because not verified i think) or nandwrite(much safer?)

2. The easy way to populate the envs mtd is to save it in serial console after the u-boot was flashed and reboot (The harder way is format it as an u-boot image of 128K before flashing).

Since i have original mtd1 backup (which has serial number and my original mac) for this i think i will format partition and dd or nandwrite it.I think i will use hard way.

Actually i didn't quite understand this question.(Sorry it is late in here and my iq level is dropping.)I want to boot all my system on NAND i will set it and forget it no USB devices needed.I know using system like this will wear out NAND flash but i don't care if it brokes some day i can always solder new one.So is UBIFS the right choice for this purpose right?

Thanks again for your great support.

It is ony a warning, it is OK ignore it. To make it perfect, iirc somewhere in the DTS must be modified for this chip. The DTS currently being used works for all MVEBU boxes stock NAND chips.

Looks like there was error in the initializtion so they are read-only.

So I need to take a look at this a bit closer.

> Also could you please make dtb for this layout?Or

Yes. The current DTB in kernel linux-5.8.5-mvebu-370xp-tld-1 is good. The MTDs definition actually is from the bootargs mtdparts. The mtd partitions definition in the DTS is not relevant.

> I can take my original mtd0 backup fill it with ff

Not dd (never use dd to flash u-boot or envs). nandwrite is the tool. And don't manually fill with ff(s) either.

Either use the -p option to let nandwrite pad the empty space for you. Or do it in 2 steps: use dd to write the new u-boot image to a new file which has the size of 0x00180000 (1.5 MB), and then use nandwrite to flash.

> Since i have original mtd1 backup (which has

Yeah, I forgot that you have mtd1 backup! that's the better way, use nandwrite to flash.

Yes, UBIFS is the right choice. So to do that, you need to check to see if ubifs commands are available in u-boot. And the env will let the kernel know such file system is used (in the bootargs).

Hi All,

To assess the amount of work involved in extracting the patches from the stock RN102 U-Boot and apply them to a recent U-Boot, I downloaded the mainline v2011.12 release and the Marwell/Netgear implementation to create the diff-file (attached):

wget https://gitlab.denx.de/u-boot/u-boot/-/archive/v2011.12/u-boot-v2011.12.tar.bz2
tar xf u-boot-v2011.12.tar.bz2 
wget https://www.downloads.netgear.com/files/GPL/ReadyNASOS_V6.6.0_WW_src.zip
mkdir ReadyNASOS_V6.6.0_WW_src && (cd ReadyNASOS_V6.6.0_WW_src && unzip -q ../ReadyNASOS_V6.6.0_WW_src.zip)
ln -s ReadyNASOS_V6.6.0_WW_src/u-boot-2011.12-armada370 u-boot-v2011.12-armada370
diff --recursive --ignore-all-space --ignore-blank-lines u-boot-v2011.12/ u-boot-v2011.12-armada370/ > u-boot-v2011-12.diff

Number of patches:

egrep '^[0-9]' u-boot-v2011-12.diff | wc -l
630

Number of source code lines modified or removed:

egrep '^<' u-boot-v2011-12.diff | wc -l
622

Number of source code lines modified or added:

egrep '^>' u-boot-v2011-12.diff | wc -l
3698

Number of files modified:

egrep '^diff' u-boot-v2011-12.diff | wc -l
97

Number of files added:

egrep '^Only in u-boot-v2011.12-armada370/' u-boot-v2011-12.diff | wc -l
39

Number of files deleted:

egrep '^Only in u-boot-v2011.12/' u-boot-v2011-12.diff | wc -l
16
egrep '^Only in u-boot-v2011.12/' u-boot-v2011-12.diff | egrep -v .gitignore | wc -l
0

My conclusion: The Marwell/Neatgear U-Boot implementaion is very different from the original v2011.12 version. It makes little sense to try to apply the 630 patches to a recent version.

In theory, that's an ideal situation. But U-boot has gone through architectural changes a few times.

Which makes it insane. All work and no play makes Jack a dull boy.

It may make more sense to add support for RN102 in the upcoming U-Boot v2020.10. Support for Marvell Armada 370 and XP SoC was added to mainline U-Boot already in 2015 and was aligned with the Linux 5.x device tree last year. "This file contains the definitions that are common to the Armada 370 and Armada XP SoC". So maybe it's no big deal to add support for RN102 (and RN104). Any thoughts?

So I need to take a look at this a bit closer.

I think i have figured it out by changing partition sizes on mtd0 and mtd1 but i am not sure if it is the right way to do it.According to here it must be a multiple of the block-size of the flash chip so i have used this bootenvs:

Marvell>> mtdparts=pxa3xx_nand-0:0x200000@0(u-boot),0x200000@0x200000(u-boot-env)
Marvell>> mtdids=nand0=pxa3xx

I let the kernel boot, it didn't complain about read-only stuff this time.Log is attached to post.
Then i checked if mtd sizes are correct:

Mounted another USB drive which contains my compiled nand u-boot and stock u-boot-envs:

root@Neutron:/# mount /dev/sda1 /media/

root@Neutron:/# cd /media/

Tried to erase and flash mtd0 and mtd1 but flash_eraseall seems doesn't work with MLC nand only ubifs seems to work, I may be wrong on this:

root@Neutron:/media# flash_eraseall -j /dev/mtd0
flash_eraseall has been replaced by `flash_erase <mtddev> 0 0`; please use it

Then i rebooted device but it seems nandwrite didn't write anything in mtd0 and mtd1.Any recommendations?Can u-boot and envs flashed with UBIFS instead of nandwrite(JFFS22)?

Yes. The current DTB in kernel linux-5.8.5-mvebu-370xp-tld-1 is good. The MTDs definition actually is from the bootargs mtdparts. The mtd partitions definition in the DTS is not relevant.

I have used your dtb while compilinf bootloader i compiled fine:

**** [Creating Image]	*****


 Ext. headers = 1, Header size = 76160 bytes Hdr-to-Img gap = 0 bytes
New image size = 0xbdf44[778052] Source image size = 0xbdf44[778052]
====>>>> u-boot-a370-2.1WP-nand-db-uart.bin was created

 Ext. headers = 1, Header size = 81920 bytes Hdr-to-Img gap = 0 bytes

====>>>> u-boot-a370-2.1WP-nand-db.bin was created
====> moved mv u-boot-a370-2.1WP-nand-db.bin u-boot-rn102-nand.bin

Yes, UBIFS is the right choice. So to do that, you need to check to see if ubifs commands are available in u-boot. And the env will let the kernel know such file system is used (in the bootargs).

In u-boot i have ubi command set so i think it works.

@tme
If you have any tutorial about porting u-boot or patching USB3.0 drivers to netgear stock u-boot i can try to compile and build something but i can't promise since i am a beginner in software stuff.

Regards.

1. I think i have figured it out by changing partition sizes on mtd0 and mtd1 but i am not sure if it is the right way to do it.According to here it must be a multiple of the block-size of the flash chip

OK, so comparing the 2 definitions. Keep in mind that the erase block size for this NAND is 2M (0x00200000).

Old:

dev:    size   erasesize  name
mtd0: 00180000 00200000 "u-boot"                # this is 1536k (1.5M)
mtd1: 00020000 00200000 "u-boot-env"         # this is 128K
mtd2: 1ffe60000 00200000 "rootfs"                 # this is the rest of NAND so we dont care where

So the total size needed for u-boot is 1664K. Rounding it up to 2M.

New:

dev:    size   erasesize  name
mtd0: 00200000 00200000 "u-boot"
mtd1: 00200000 00200000 "u-boot-env"
mtd2: 1ffc00000 00200000 "ubifs"

This new definition above is not going work. The envs area must start at 1536k, and it is 128K large.

What you should do here is defining mtd0 of 2M, and mtd1 of 128K. mtd1 should start at offset 1536k (it is OK to do that, like an overlay file system, where mtd1 is inside mtd0). And then keep mtd2 the same.

Therefore,

setenv mtdparts 'mtdparts=pxa3xx_nand-0:0x200000@0(u-boot),0x20000@0x00180000(u-boot-env),-(rootfs)'

And then, the /etc/fw_env.config will need to conform to the new definition. But we will worry about that later.

2. Then i rebooted device but it seems nandwrite didn't write anything in mtd0 and mtd1.Any recommendations?Can u-boot and envs flashed with UBIFS instead of nandwrite(JFFS22)?

No, UBIFS cannot be used for u-boot and envs. They are raw, i.e. must be flashed as binary. The BootROM expects u-boot to be a raw binary. And u-boot also expects the envs area to be raw.

Unfortunately, I think it is the NAND chip type MLC that might be the issue here. However, I need to see the bootlog if you have one. Don't worry about the envs just yet.

Start kwboot, set the mtds:

setenv mtdparts 'mtdparts=pxa3xx_nand-0:0x200000@0(u-boot),0x20000@0x00180000(u-boot-env),-(rootfs)'

Boot into Debian, flash the u-boot image

Flash u-boot with -p option:

nandwrite -p /dev/mtd0 u-boot-rn102-nandwithdtbmtd0.bin

And reboot. And post the boot log if there is any output at all.

NOTE:

I tend to conflate the term raw and JFFS2 here. But you get the meaning. OTOH, UBIFS is a real filesystem just like Ext2 or Ext3.

Bodhi,
Before starting to avoid any conflict previous writes i erased nand chip again.

I have tried with your mtd envs:

Marvell>> setenv bootcmd 'usb start; run usb_bootcmd; usb stop; reset'
Marvell>> setenv fdt_skip_update yes

Attached full log on post.

It didn't complain about u-boot mtd but complained about u-boot-envs and ubifs partitions:

Flash:

nandwrite -p /dev/mtd0 u-boot-rn102-nandwithdtbmtd0.bin

Verify:

dd if=/dev/mtd0 of=/media/mtd0afterwrite.bin
diff u-boot-rn102-nandwithdtbmtd0.bin mtd0afterwrite.bin

And reboot.

If the header checksum is bad again, check how the u-boot image was created during the build.

I have already tested my NAND Image (u-boot-rn102-nandwithdtbmtd0.bin) with kwboot it boots fine and checked first byte which is 8b i checked it (wtarreau blog) and it points it is a NAND image so i think NAND image is fine.
But when i rebooted system after writing with nandflash line above and loaded u-boot uart and tried nand dump 0 it is all FF.

How this could be happening?The diff says no difference, cat command also same case.

Another solution to this problem i think maybe we can write u-boot via tftp but i don't know which address must i load:

The contents look fine (note the 8b at the beginning which means that this is a NAND flash image). If everything looks OK and only in this case, you can write the memory contents down to the flash then control that it looks similar to the dump above :

Marvell>> nand write 0x7000000 0 0x00400000
Marvell>> nand dump 0

Then reset the device, it should reboot directly from the flash. If it fails, you just have to retry the procedure above and figure what you got wrong.

Marvell>> reset

Which address i must use for my box above Willy's example?
Regards.
Edit:
After reboot i checked mtd0 again if contents are changed:

root@Neutron:/media# dd if=/dev/mtd0 of=/media/mtd0afterwrite.bin
4096+0 records in
4096+0 records out
2097152 bytes (2.1 MB, 2.0 MiB) copied, 0.70676 s, 3.0 MB/s
root@Neutron:/media# diff u-boot-rn102-nandwithdtbmtd0.bin mtd0afterwrite.bin
Binary files u-boot-rn102-nandwithdtbmtd0.bin and mtd0afterwrite.bin differ
root@Neutron:/media#

Nothing has changed.
Edit2:
I just realized in u-boot nand info says:

Marvell>> nand info
Device 0: nand0, sector size 64 KiB
  Page size      8192 b
  OOB size        128 b
  Erase size    65536 b

But in kernel:

nand: 8192 MiB, MLC, erase size: 2048 KiB, page size: 8192, OOB size: 744

Erase size and oob sizes are different.Is this relevant in our case?



Edited 4 time(s). Last edit at 09/19/2020 04:25PM by whitepawn.

whitepawn,

I forgot one step in verifying the nandwrite.

Make it 2MB even:

dd if=u-boot-rn102-nandwithdtbmtd0.bin of=u-boot-rn102-nandwithdtbmtd0.kwb bs=2048k conv=sync

So no padding is needed in writing:

nandwrite /dev/mtd0 u-boot-rn102-nandwithdtbmtd0.kwb

And verify. It should show the 2 binaries are identical:

dd if=/dev/mtd0 of=/media/mtd0afterwrite.kwb
diff u-boot-rn102-nandwithdtbmtd0.kwb mtd0afterwrite.kwb

Try booting one more time after the diff verification showed the write was OK.

Yes. It is a big difference. That's what I said above

Quote

Unfortunately, I think it is the NAND chip type MLC that might be the issue here.

The BootROM saw NAND with the info above. So it might choke at some point. But we have gone this far, so might as well trying all alternatives. (The BootROM code is proprietary so we don't really know how it detects NAND). And I hope that it can be corrected by u-boot (but not sure).

And you got the right idea to try flashing in serial console, if flashing in Linux does not get to a good boot. Let me look at the address and post the command later.

Are there any difference between nandwrite and tftp nand write?
Tftp write from u-boot is like dd so no control ecc or fancy stuff i guess.

That flashing was not good. Look at the nandwrite command options (2.1 MB is not the expected dump file size).

Ok. Let's regroup.

Bodhi,
Yes you are right but "i also like to live dangerously"

Remember the previous posts above? that "living dangerously" has come back and bitten you in the rear :)

Testing should be very methodical and we'd want to eliminate as much variables if we can, in each step. We don't want to test new u-boot and new NAND at the same time.

So, now to eliminate the unknown variable about the new NAND, you should flash the mtd0 backup file to mtd0 (not the new u-boot kwb). And then reboot to see if the new NAND is working.

If you had kept the original NAND, then you would flash the new u-boot to it. And see if the new u-boot is working.
