Dear Jos? Miguel Gon?alves,
Jumping to board_init_r is not performed due to a bug on address
computation.
Is your CONFIG_SYS_TEXT_BASE configured correctly? I don't detect any
misbehavior on my arm926 boards.
Maybe because you are not using it to build an SPL?
I do ... and I use CONFIG_SPL_TEXT_BASE properly .
Please check the same chunk of code in other start.S for arm1176 and
armv7. They have the same code that I put for arm926ejs.
Please wait and please first explain what is the issue.
The issue is what I've explained in the patch comments.
"Jumping to board_init_r is not performed due to a bug on address computation."
Ok, I don't know how to replicate the bug from this comment or what effects it
causes or ... well, anything. So please, try to be more elaborate in your patch
description next time. Anyway ..
Without this
change the code never reaches board_init_r in the SPL and I think I have
all the configurations correctly set.
I wonder why you'd ever want to reach board_init_r in the SPL. SPL is there only
to load the real U-Boot from whatever media, so you usually use either NAND SPL
Here's a good point for me to jump in, I think. There's two things to
understand:
- In the current in-tree SPL implementations the code flow is
board_init_f calls relocate_code() to clear the BSS _and_ get our jump
to board_init_r. It does not actually relocate the running U-Boot,
just clears the BSS. board_init_r is what calls the things to load
and boot the next stage (U-Boot or Linux).
- In my series this has been changed slightly to be board_init_f calls
memset and then board_init_r directly. So this patch should not be
needed once rebased on that series.
OK Tom. I will start working on rebasing the MINI2416 board support on the new SPL
framework.
If I have any doubts I will get in touch with you...
Best regards,
José Gonçalves
