Show U-Boot variables

Package: u-boot-tools (Ubuntu, MintPPC etc.)
Command:
fw_printenv
Edit the file fw_env.config in /etc. To create this file, you need to know information about where U-Boot stores its env variables. Specifically, you need the mmcblk device name, the device offset, the env size and the flash sector size.
fw_env.config file:
Code: Select all
# Configuration file for fw_(printenv/setenv) utility.
# Up to two entries are valid, in this case the redundant
# environment sector is assumed present.
# MTD device name Device offset Env. size Flash sector size
/dev/mmcblk0 0x99C00 0x4000 0x100
Unfortunately we don't know the device offset, the env size and the flash sector size.

The comments in the file you show above mention also an fw_setenv utility.
Does this work under Linux on your X5000? Both /20 and /40?
Best regards,
Niels

I get the U-Boot variables with PuTTY via a null modem RS-232 serial cable.
PuTTY log:
PuTTY_X5000_40_U-Boot.log

No, it doesn't because I don't know the device offset, the env size and the flash sector size.

@xeno74:
Try contacting Tony Wyatt directly - I believe he can't read the Linux groups here. But I'm relatively sure he can help.
Best regards,
Niels

Maybe this fw_env.config file works:
Code: Select all
# Configuration file for fw_(printenv/setenv) utility.
# Up to two entries are valid, in this case the redundant
# environment sector is assumed present.
# MTD device name Device offset Env. size Flash sector size
/dev/mmcblk0 0x89200 0x2000 0x200
Thanks a lot to Skateman and Jamie Krueger for the values.

I have tried the Values but did not work on my machine... (might be due to the 2018 Olson U-Boot version)
With a "stock" u-boot version that came with the X5K the above values could work.
(would be nice if that could be tried by someone)
Further investigation needed regarding the later 2018 Olson u-boot.

It works with MintPPC on my X5000/40!

Great!!! Good thing it works on your machine.
