Re: [U-Boot] environment access before relocation does not work on (some) arm

Dear Matthias Fuchs,

In message 4FED7877.2020505@esd.eu you wrote:

I just noticed that using getenv (and friends) does not work on ARM (namely i.MX28) from board_init_f() after running through the init_sequence.

This is normal, and documented. Before relocation, you must not use getenv().

Env access does not work before env_relocate() in board_init_r().

It does, but you have to play by the rules, i. e. use getenv_f() instead.

Didn't this behave different sometimes before? Even after the big env rework?

No. The use of getenv() before relocation has never been supported. It may have worked (by pure chance) on some systems, but that's all.

Best regards,
