Bricked or not, that is the question :/
November 08, 2018 09:18AM
hi all,

i recently flashed my stora with the latest uboot from https://forum.doozan.com/read.php?3,12381,12381#msg-12381

all was ok, netconsole was working ok, etc.... But ( as i am a noob :=0 ) i have done a "env default -a" i directly loose my netconsole, and the only choice was a reboot. Since this day, it seem i have a brick....

is there something to do/test to make it alive ?

ps: for an unknown reason i never had serial output/access even with stock uboot...

thx all.

It is very far from bricked :) Even without serial console, you can still fix this with uEnv.txt.

Do you keep the log of your u-boot flashing session? it would be good to have in case I need to ask question.

Let find my instruction post for this or write a new one.

Here is how you restore the u-boot envs to default values during boot.


Booting with the default envs using uEnv.txt loading capability using uboot.2016.05-tld-1.environment (the content of the default envs in text format).

This assumes that you have install my latest u-boot release. The uboot.2016.05-tld-1.environment file is in the downloaded tarball.

This assumes that you have the rootfs on USB drive. If your rootfs is on HDD and you cannot take it out of the box, then create a new USB rootfs using Debian-4.12.1-kirkwood-tld-1-rootfs-bodhi.tar.bz2. Basically, you need to access this drive to copy the envs file to the rootfs.


1. Copy the default envs in text format to the rootfs on USB. Assuming the USB rootfs is mounted on another Linux box as /media/sdb1.

Become root and copy the default envs to uEnv.txt:
su -
cp -a uboot.2016.05-tld-1.environment /media/sdb1/boot/uEnv.txt

2. Modify the uEnv.txt for your box specifics to replace the 2 envs devices and dtb_file as following:

devices=usb ide
dtb_file=/boot/dts/kirkwood-netgear_stora_ms2000.dtb

Note:

- The devices env above indicates that u-boot will attempt to boot with the USB first, if it is not present then it will try to boot HDD.
- The dtb_file above indicates that you are booting the Netgear Stora box. This instruction is applicable to all Kirkwood boxes, just change the corresponding DTB file name if you booting other boxes.

3. and then sync and unmount the USB

sync
umount /media/sdb1


4. Plug in this USB rootfs to the box, and power up.

You should find your box again in the nextwork and log in your usuall way as before.

and thx for your answer.

i tried with 2 differents usb key, with ext3, ext4 and nothing. it do not even try to access the key. Any other voodoo tricks i can try ?

Which exact version of new u-boot that you have flashed to NAND? do you keep the log of what you did to flash?

hi,

i didn't have log of the session when i burned:

uboot.2017.07-tld-1.netgear_ms2110.bodhi.tar
md5
1b09317e896ad928104a1edce459a9f5

8f5e8b5b33e3979b05698a09a92f99cd41ed04121993058f9b2469122fd280a7

but be sure that all was ok, i had my linux working, etc...

i installed netconsole with env var, and all was ok but net console gave me prompt instead of counting from 10 to 0 to boot.

i just clear the preboot env var thinking that will force it to boot normaly.

i'm pretty sure it stall at a uboot prompt. but without any serial i cani't investage more.

it smell that this time you will tell it's bricked.... argggg :/

So it was flashed successful. u-boot is OK on NAND mtd0. You have not done anything to change it if you just wiped out the envs.

There was some wrong setting in your netconsole set up. So you could have fixed this issue at the netconsole prompt.

No. It is not bricked. The envs are just messed up, so you can't boot the kernel. uboot.2017.07-tld-1.netgear_ms2110 should be able to read the uEnv.txt and correct that.

If you can connect serial console then this problem can be solved very quickly. So if you can do this, then we will wait until you boot with serial console.

------

If you can't connect serial console (for whatever reason) then we just have to work on the rootfs and make sure that it is good and have the uEnv.txt in /boot. Without console visibilty, we need to rely on the LEDs to guess where the booting process is at.

1. I assume you were booting with SATA rootfs, no USB? can you take it offline and mount it on another Linux box?

2. If you can do number 1, then do this to make sure your rootfs is OK. Assuming it is mounted at /media/sdb1

ls -lart /media/sdb1/boot
ls -lart /media/sdb1/boot.dts/kirkwood-netgear_stora_ms2000.dtb
e2label /dev/sdb1

Please post the output of these 3 commands above.

3. Put the uEnv.txt in /media/sdb1/boot/. And modify the content as

devices=ide
dtb_file=/boot/dts/kirkwood-netgear_stora_ms2000.dtb

If you'd like, post the content here for confirmation:

cat /media/sdb1/boot/uEnv.txt

------

After we've verified that the rootfs is OK. Do a sync and then umount

sync
unmount /dev/sdb1

Take it back to the Stora. Power up. And observe the HDD lights or feel the drive to see if it was accessed during you power up. And then observe and record the LEDs behavior.

See if it gets you to boot successfuly.

alonetrio,

Did you ping this IP address while the box is powering up?

On another Linux box, execute the ping
ping 192.168.0.231
And then power up the Stora.

Also, when you did this:

i have done a "env default -a"

Did you also run saveenv command like this?

saveenv

bodhi,

still nothing new. no ping.

yes, env default -a, perhaps cleared the bootcmd env var, then saveenv.

i tried something :
for now, when i plugged the power cord, the stora power on automatically, i decided to remove the battery ( i don't know what it save, clock, something else ? ), replace the battery, now i need to press the power button to get it powered on. Still same effect on the boot side, but it's now a bit different.

You did not report the whole story before. But clearing the bootcmd and then saveenv is why it cannot be recover with uEnv.txt.

Now I declare that it is bricked :) Sorry, you need serial console to receover.

Re: Bricked or not, that is the question :/

AloneTrio,

Not JTAG. Serial console is easier and cheaper. Open the box and find serial console header for this box.

The pinout info is in this forum before in some thread that I forgot to save the link.

May be just wrong connections (Tx/Rx)... things like that. People has connected serial console successfully before on the Stora.

Yes. kwboot to boot the latest Stora u-boot, which should boot your current rootfs right away. After logged into Debian, do the flashing again in command line as before.
