hi bohdi,
well, i would prefere to use "your" rescue image, so that i can use your env completely...

jay
Hi jay,

I don't have rescue system installed on my plugs. I've only installed Jeff's resue system on one of my GoFlex Nets as an experiment.

:) I think either from Jeff's or davygravy's rescue system envs. Incorporate either settings into my envs is not difficult. If you have trouble, let me know.

Hi

I'm trying to flash my u-boot for the first time, but when following step 6 I receive the following message:
Quote
/i-data/fe8bf781/admin # flash_erase /dev/mtd0 0 4
-sh: flash_erase: not found


Then I downloaded the flash_erase given in the description when my system hasn't got flash_erase, but then I receive the following message:
Quote
/i-data/fe8bf781/admin # sh flash_erase /dev/mtd0 0 4
flash_erase: line 1: syntax error: unexpected word (expecting ")")


I did then some more research and my system knows the command: flash_eraseall, but then the output is totally different then what is in the guide and nothing more:
Quote
/i-data/fe8bf781/admin # flash_eraseall /dev/mtd0 0 4
Erasing 128 Kibyte @ e0000 -- 87 % complete.


Can someone help me how I could procedure the next steps...

Friendly regards

Hi

And ow yes I forgot to mention, but I'm using the following device: Zyxel NSA325 v2.
Also I have a serial connection at hand if needed.

sh flash_erase

This command is a wrong way to execute it. When you download a binary and want to execute it, cd to the directory where the binary is and:
./flash_erase /dev/mtd0 0 4

Quote

flash_eraseall /dev/mtd0 0 4

You should never execute a flash_eraseall like above. Use flash_erase only to avoid mistake. And flash_eraseall has been deprecated, too.

With all that said, what you did above did not hurt anything. However, when messing with NAND, it is best to ask question first, don't try to test a command that you're not sure if it works :)

Before proceeding, please post output of:
uname -a

Hi ziggy,

Your system info looks OK.

You can proceed with the installation, however, I did not like the look of the output you've shown in step 6. So proceed but starting from step 6. And the expected output shoutd be like shown in the instruction:

6. Erase mtd0
./flash_erase /dev/mtd0 0 4

Expected output:
Erase Total 4 Units 
Performing Flash Erase of length 131072 at offset 0x60000 done

Many thx for your help!

I performed step 6 again and get a correct output:
/i-data/fe8bf781/admin # ./flash_erase /dev/mtd0 0 4
Erase Total 4 Units
Performing Flash Erase of length 131072 at offset 0x60000 done

but after performing step 7 I don't receive a correct output:
/i-data/fe8bf781/admin/tmp # nandwrite /dev/mtd0 uboot.2014.07-tld-4.nsa325.mtd0.kwb

ok, because in setp 7 the expected output should look like this:
Writing data to block 0 at offset 0x0 
Writing data to block 1 at offset 0x20000 
Writing data to block 2 at offset 0x40000 
Writing data to block 3 at offset 0x60000

In my output I don't see an offset.

I proceeded but now I'm stuck on section B at sub d: Flash u-boot envs to NAND location 0xC0000.

The first step succeeded:
/i-data/fe8bf781/admin # ./flash_erase /dev/mtd0 0xc0000 1
Erase Total 1 Units
Performing Flash Erase of length 131072 at offset 0xc0000 done
But the second I receive the following output when doing this command:
/i-data/fe8bf781/admin/tmp # nandwrite -s 786432 /dev/mtd0 uboot.2014.07-tld-2.environment.img
output:
Writing data to block c0000

This is not exactly the same as the output it should give:
Writing data to block 6 at offset 0xc0000

This is fine. The output of different version of nandwrites are slightly different, but it is correct. The version you've downloaded from Jeff's site is older.

After you've gone through all the steps, if you'd like me to look over, post tthe entire log of what you've done before reboot.

Hi bodhi,

I have a nsa325v2. I had changed the /etc/fw_env.config to get it readable as described here: https://micha.stoecker.me/p/X9M4
I followed your description except the fw_config.
You write in section B to /dev/mtd0, but the uboot_env resides in /dev/mtd1! Is that correct?

root@debian:/mnt/sdc1/uboot# cat /proc/mtd
dev: size erasesize name
mtd0: 00100000 00020000 "uboot"
mtd1: 00080000 00020000 "uboot_env"
...

I already executed succesfully the 2 following commands, but fw_printenv showed my old environment.
commands:
./flash_erase /dev/mtd0 0xc0000 1
./nandwrite -s 786432 /dev/mtd0 uboot.2014.07-tld-2.environment.img

After changing /etc/fw_env.config as you described to /dev/mtd0 0x2000... it shows the new environment.
The saved environment has only variable ethaddr, but not mtdparts and rootfstype.
What should I do before reboot?
Should I restore?
What would be the right command to restore the saved mtd0?

It's all good!

No need to restore.

Set your mtdparts and check rootfstype. I believe you have the new rootfs type Ext3?
fw_setenv mtdparts 'mtdparts=orion_nand:0x100000(uboot),0x80000(uboot_env),0x80000(key_store),0x80000(info),0xA00000(etc),0xA00000(kernel_1),0x2FC0000(rootfs1),0xA00000(kernel_2),0x2FC0000(rootfs2)'
If it shows ext3 here:
fw_printenv rootfstype

then reboot.

Hi bodhi,

reboot worked, but u-boot cannot find kernel. The usb stick has 2 partitions sda1 (ext2 boot) and sda2 (ext4 root)
So your default configuration does not work.

 (Re)start USB...^M
USB0:   USB EHCI 1.00^M
scanning bus 0 for devices... 4 USB Device(s) found^M
       scanning usb for storage devices... 2 Storage Device(s) found^M
** File not found /boot/uImage **^M
** File not found /boot/uInitrd **^M

I tried with:
setenv usb_root /dev/sda1
setenv usb_load_uimage 'ext2load usb $device 0x800000  /uImage'
setenv usb_load_uinitrd 'ext2load usb $device 0x1100000 /uInitrd'

and u-boot loads the kernel, but then stops as there is no rootfs in sda1.
Is there no ext4-support in u-boot?

I tried the following commands also without success:

setenv usb_root /dev/sda2
setenv usb_load_uimage 'ext2load usb $device 0x800000  /boot/uImage'
setenv usb_load_uinitrd 'ext2load usb $device 0x1100000 /boot/uInitrd'
setenv rootfstype ext4
saveenv
boot
and
setenv usb_root /dev/sda2
setenv usb_load_uimage 'ext2load usb /dev/sda1 0x800000  /uImage'
setenv usb_load_uinitrd 'ext2load usb /dev/sda1 0x1100000 /uInitrd'
setenv rootfstype ext4
saveenv
boot

How is the correct env parameter setting?

It works if you follow the instruction when creating rootfs :) When you install anything, instruction are to be followed exactly as written, unless you are an experienced embedded Linux user. And you should not assume that the instruction does not work ;) Always assume that you have done a wrong step somewhere and review your installation log.

Updated 24 Feb 2015:

This rootfs is the first Debian jessie rootfs in my Kirkwood kernel/rootfs release series, and to keep in sync with kernel Linux-3.18.5-kirkwood-tld-1.
...
1. Format a new USB drive with a single Ext3 partition, and label it rootfs. Note: if your existing uBoot env for rootfs type is ext2, then you might want to keep it consistent and use Ext2 USB drive. It will work with Ext3 drive without problem, though.


See the explanation (also found in my signature) for problems might arise when booting with multiple-partition USB/HDD drive:
http://forum.doozan.com/read.php?3,19093

So the bottom line is you should have a single partition type Ext3 for your rootfs (you can choose Ext4, but with a single Ext4 partition, no swap). And then after everything is working, consider swap file or partition. I'd recommend swap file, because of the flexibility it'll provide, and the simplicity of the rootfs structure.

so does this new uboot enable the booting from the original Pogoplug software by default, or I have to set this in the uboot env?

the current uenv_read_disk settings seems to only read /boot/uEnv.txt while the booting device is mmc?

uenv_read_disk=if test $devtype -eq mmc; then if $devtype part; then run uenv_read;  fi; else if $devtype part $disknum; then run uenv_read; fi;  fi

Can I just change the mmc to usb in this string to make it read the /boot/uEnv.txt from usb drive?

I have this setting in the /boot/uEnv.txt
usb_root=LABLE=ROOTFS
boot usb driver's partition lable is ROOTFS,

will this be suffice to make it always booting from this usb drive, regardless of how many usb drivers are attched?

No, it scans all kind of drives for uEnv.txt.

This is for picking the right rootfs only. To detect the system drive (find uImage):

@bodhi,

i'm trying to flash the new u-boot for nsa310s but i'm a bit scared of those bad blocks you're mentioning in the tutorial. My dmesg is this:

[    1.982828] Bad eraseblock 100 at 0x000000c80000
[    1.992505] Bad eraseblock 200 at 0x000001900000

Is it safe to flash? Or i need some workaround? I'm a bit confused about this considering your warning:

Be sure there is no bad block in the first 1M of your NAND (check dmesg).

Johnny,

It is OK to flash. Your bad blocks are not in the 1st 1M (block 0 to 7).

@bodhi, thanks! it worked!
Stock bootloader got too annoying, too much reports of people with issues with my script, caused by u-boot not recognizing stuff.

So, I installed the NSA325 uboot, then I flashed default envs, then I made some modifications to get it to boot FDT kernel.

did some cleanup and re-arranging, I was planning to dump the nand block to get a proper FDT default envs people could flash more easily than flashing a non-FDT one and then rewriting half of it for FDT booting.

these are my envs, assuming Debian is in an ext4 partition with label "rootfs".

the only thing needed is to change board_dtb and arcNumber with the right one after flashing it.

How do I generate the dump of these envs so they can be flashed easily?

You could generate your own now, or wait till I release a DTB-enable u-boot env image? I have prepared such image, but have not have time to release it.

Only if it is cooler than mine, lol. :D

Anyway, did you use mkenveimage? http://free-electrons.com/blog/mkenvimage-uboot-binary-env-generator/
are u-boot envs single or redundant? (i think single)
Of course it is cooler :)

In any case, here is the binary from my 2014.07 build.

md5
c46b7ffa8b164a2017e065ad2582eda2 mkenvimage.tar

Use this command to generate image from uboot.environment file.

./mkenvimage  -s 131072 -o uboot.environment.img uboot.environment


The env file should contain the envs in name=value format. For example, the one I've released:

Quote

uboot.2014.07-tld-2.environment (the content of the default envs in text format)

or take the list that you posted above, put them inside the uboot.environment text file.
