LaCie NS2 - *** Warning - bad CRC, using default

Hi!

Updated u-boot, environment variables are lost.
Connected via UART.
After rebooting, the CRC error appears again and the variables are not saved.
Tried commands "env default -a", "saveenv", "env save" - no result.
Ask for advice.

Did you get this u-boot image from somewhere? If you built it, how was this u-boot built? from a clone of u-boot mainline?

And why the commit is at 00057-gfce0bb3e2bd8? If u-boot version is exactly as U-Boot 2020.07-rc5 then the commit is 868fb9969c85ce5a1b33c6bb713c8158c04acee9.

If you can, post the u-boot images: the image you used to flash it, and the current image you can dump after you've logged into Linux.

Thanks for advise!

OK I think it must be a bug in this u-boot version (probably inherited from mainline).

I don't know what changed this u-boot has on top of mainline u-boot. And you're installing using the Debian mainline installer, which we don't use here.

======

You could try my installation using my rootfs.

Boot Kirkwood rootfs with stock u-boot
https://forum.doozan.com/read.php?2,102054,105374#msg-105374

After successful booting into Debian on USB rootfs, we'll save the envs in Debian.

If the problem is what I think it is, there is a work around to get it working.

======

To fix this problem for good, I need to patch the latest u-boot for Lacie boxes. But this requires a tester to test my builds (it's a bit tedious and repetitive), since I don't have the hardware.

We are not out of option yet! let me build a new u-boot for you to try.

Please try kwboot this image over UART. See here for kwboot example:

https://forum.doozan.com/read.php?3,51739,51919#msg-51919

After it was loaded and run, interrupt serial console countdown and repeat the test. Also good to see what's in the internal envs.

Enviroment is saved..... and lost uart access from windows and linux termilal. But now I can access via kwboot from linux desktop.

That worked for the old 2011u-boot.

You did not run the new u-boot. Pease see above for the new u-boot uboot.2025.01-tld-1.netspace_v2.kwb. But still, whatever works is good!

Is the Virtual Box running on a x86 PC?

This u-boot has SPI flash, not NAND flash. So the above is not correct.

See the Dreamplug u-boot for example:

dm7000s,

You lost serial console because it tried to start netconsole.

bootcmd=dhcp && run netconsole; if run usbload || run diskload; then bootm; fi

Rerun kwboot like you did above. And at serial console prompt, before booting to Debian, adjust the bootcmd

setenv bootcmd 'if run usbload || run diskload; then bootm; fi'
saveenv

Or just do a reset, and it will boot the u-boot on flash, since you have flashed it.

Ah, this u-boot current config is too old for 2025.01. Let me reconfigure and rebuild it.

dm7000s,

This u-boot has been neglected for so long. It will take more time than I have to modernize it.

So I'd suggest you stay with the version "U-Boot 2011.12-00260-ga24d58e (Feb 17 2012 - 15:48:09) NS v2".

Agreed.
For me is faster to extract the eeprom from the board, flash it and return it back. Access via uart is back.
Thanks for the assistance, I will wait for the new version. It is not urgent. It was an interesting experience.
