revive Medion oxnas stg-212

I'll try from scratch tomorrow again. It's almost 3am over here, need to catch some sleep. Thanks again for your patience! If you've got any other ideas or hints i can try tomorrow, let me know. It seems very promising, if that data gets written correctly. I could try recreating that rescue disk once again, without erasing the files that gets created by build.sh during the process to get written on the specific sectors of the disk and then i could try to write those files to NAND!?

Any chance to check that on the box?

On the one hand it would be pretty annoying, but on the other it would mean I'm not that stupid at all understanding all those different options to boot Debian/OpenWRT from hdd, usb or NAND and still failing at some point (mostly decompressing Linux to RAM then)... :-/

Boot back to stock u-boot on HDD. At serial console prompt,

memtest

This box is not the Pogo V3 Pro/Classic. So there might be peculiar things I do not know about.

The flash is 128MB in Hex 7FFFFFF

The flashing command adds up 2240000+5dc0000-1=7FFFFFF (128MB) and -1 because the first byte is written to 2240000

What if you try to write 5dbffff bytes. Do you get the same error?

Schnee

hey schnee, thanks for getting back! unfortunately seems so:

NAND write: device 0 offset 0x2240000, size 0x5dbffff

 0 bytes written: ERROR

I am not an expert, but looking at your logs, the flash has a bad block, so your total size is 128mb-bad flash block size.

I would try to reduce last write with 1 block size and see if that helps. Hopefully nothing important is stored at the end of the flash.

As I remember the typical block sizes are 512, 2,048 or 4,096 bytes. Reduce the data size with these values and see what happens. Start with 512.

Schnee

ok, it took a while of thinking about it, but at least it's writing now...

sektor to start writing from in hex is 2240000 and complete ram is 7FE0000 that means there is just space left for writing filesize of 5DA0000 (not sure if there is a typo in build.sh which wants to write 5DC0000, but all documentations n the net say size of mtd7 is 5DC0000).

That was it. My bad, the instruction were written for Kirkwood SoC. This SoC memory start at 0x60000000. Glad you figure it out. Thumbs up!

Don't bother with other part of NANDs. As long as u-boot is OK, it's partly done.

You can try to boot OpenWrt or Debian now.

The issue with the backup files don't match NAND could be that the backup file were dump with or without OOB or ECC. A typical nanddump to save u-boot is

nanddump --noecc --omitoob -f mtd0 /dev/mtd0

So it could be either those mtds were written with ecc and/or oob, and the files were saved without, or vice versa.

Which way would you recommend? TFTP i have to try later at home... just tried starting schnee's rescue disk again, which leads to uncompression error once more. i fear, as stock linux from NAND doesn't uncompress either, i'm going to have the same results on everything i'll try again. at least with stock u-boot i only can TFTP images... we'll see later today.

I would unplug the HDD, and boot with stock u-boot. And then boot Debian-4.14.180-oxnas-tld-1-rootfs-bodhi.tar.bz2 on USB. Remeber to do Step 4 and create new uImage with the STG-212 DTB embedded in it.

For now, ignore the problems with the other NAND partitions. When you install OpenWrt, those mtd partitions will be wiped out anywaty.

Really? I ran the Pogo V3 with USB only. Perhaps this STG-212 u-boot intentionally removed that.

Then you can boot with an HDD/SSD rootfs, but not with this SSD. Because the magic sequence is still in the raw sector, which will bypass NAND booting and go straight to SATA (hence we always said it is unbrickable because SATA booting is the rescue path).

just a short summary before heading to bed...

booting various openwrt initramfs from tftp always stuck at "Starting kernel..." - as i can't connect via browser or ssh to 192.168.1.1 nor 192.168.50.100 on subnet 255.255.255.0 or 255.255.0.0 then, i guess it's failing in uncompressing Linux again!?

USB boot isn't working with having one ext2 partition called rootfs, same with IDE boot. as there is no ext2load nor ide command included in original u-boot, i don't get how i should boot rootfs from hdd/ssd then. tried setting env on "ide 0:1" for /dts/oxnas820-stg212.dtb, /boot/uImage and so on, but without ext2load i don't know how to get rootfs from hdd/ssd started... maybe it's a bit too late for now. having to get some rest after the little success of writing stock mtds to NAND today, but honestly i still don't know how get around that uncompression error on all different openwrt or debian versions. :-(

If there is no ext2load/ext4load then use fat command or use tftp to load the kernel files. And then boot with new envs (same as for USB rootfs). All it matter is root=LABEL=rootfs. And earlyprintk=serial. So that we can see if the decompression error still occurs.

I can write it out for you if you need help.

OpenWrt kernel does not help. So we can forget about that.

USB always times out, so only solution is IDE with ext2, labeled 'rootfs', including extracted Debian-4.14.180-oxnas-tld-1-rootfs-bodhi.tar.bz2 and having /boot/dts/oxnas820-stg212.dtb + new uImage with the STG-212 DTB embedded in it.

Just to make sure, which files should i tftp now and what envs to set for them? I would go for

setenv tftp_set_bootargs 'setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 earlyprintk=serial'
setenv load_uimage 'tftp 0x800000 uImage'

alexinc,

Those load addresses are too close. Since you are running my kernel, load it like for the Pogo Pro.

load_initrd=echo loading uInitrd ...; load $bootdev $device 0x60e00000 /boot/uInitrd
load_uimage=echo loading uImage ...; load $bootdev $device 0x60500000 /boot/uImage

If that does not work, load only the uImage at 0x60500000. uInitrd is not important at this moment.

tftp 0x60500000 uImage
bootm 0x60500000

Interesting that I think I don't understand this stock u-boot.

load_nand=nboot 61000000 0 440000
boot=bootm 61000000

That's 16MB location.

So you could try

tftp 0x61000000 uImage
bootm 61000000

OK. Did you run a memtest?

Or put a heavy item on the ram / cpu and try to boot it again. :P

Yes, i tried

"mtest" without any given values is stuck at "Pattern 0000000". When running

mtest 60000000 7FE0000

it is reading and writing circulation pattern non stop until i ^C. I didn't find anything explaining on the net, how it should work - which behaviour to expect, when it's finished and so on. So not very helpful to me to this point.
I then tried mtest 60000000 1388 (for just 5mb), but it was writing those different pattern circulation again and again until i stopped it. How often will it write? How long may it take for just 5mb... questions about questions. ;-) btw. after all this mess i'm still thinking it's a hardware issue now.

last of all options, just before being on my way to the window... ;-) guess it's not me jumping!

That will help in decompression I guess :))

OK so last attempt should be reflashing the rest of the stock mtds from backups. Pay attention to OOB and ECC. If the backup files were nanddump with OOB and ECC, those files will look weird, i.e. the size is bigger than what you'd expect.
