I'm trying to modify a u-boot env arg within the kernel code. I've found boot_command_line
var in main.c
and setup.c
, which contains an arg, so that made me think it is possible, however, I coudn't find where this var is being updated with the u-boot env arg value, or how to get a different arg and then write it back
This is the wrong approach. There are user-space tools to access the U-Boot environment, fw_printenv
and fw_setenv
and that's how you access the environment outside of U-Boot.
