[U-Boot] Moving custom board imx6q from u-boot-imx 2014.04 to 2015.04 lead to freeze
Hi All,
After upgrading my u-boot-imx v2014.04 to v2015.04 I was not able to boot anymore my custom iMX6Q board. Everything seems stopping after relocation.
Last executed initcall is the setup_reloc(), and the board_init_f() will finish correctly. It seems that it's freezing somewhere within arch/arm/lib/crt0.S after calling the board_init_f().
Does anyone can suggest where to look better?
Thanks in advance, Roberto Fichera.

Why don't you try 2016.01 instead?

Ok! Will do! However I've found that with this patch below it boots pretty fine! Do you know why?

I am not sure why removing this line fixes the boot for you.
This line has been added by commit:

imx: fix exception vectors relocation in imx27
Adding Albert on Cc in case he has any ideas as to why this would impact mx6 to boot.

It has the same problem, below standard boot without apply any changes:
