Description:
I am working with an AM62x-EVM board and facing an issue with environment variable access.
My concern is that fw_printenv
is not working properly, and I suspect it may be due to incorrect configuration of the U-Boot environment offset/address.
for your ref i provided the logs : root@am62xx-evm:~# fw_printenv
Cannot read environment, using default
Cannot read default environment from file
I would like to confirm at which address uEnv.txt
(or uboot.env
) is loaded in the AM62x-EVM, so I can configure fw_printenv
correctly.
Hardware / Software Details:
-
Part Number: AM62x-EVM
-
Bootloader (U-Boot): 2025.01
-
Linux Kernel: 6.6.58
-
Storage medium: eMMC
Steps Tried:
-
Booting the board with Linux from eMMC
-
Verified boot log shows successful boot with U-Boot 2025.01.
-
Attempted to run
fw_printenv
, but it fails to read the environment. -
I suspect the
fw_env.config
file is not pointing to the correct environment address.
Questions:
-
At which address/offset is the uEnv.txt / uboot.env stored on the AM62x-EVM (for eMMC and SD boot cases)?
-
How should the
fw_env.config
file be configured correctly to accessfw_printenv
on this platform?
Thank you .
