Moving custom board iMX6Q from u-boot-imx 2014.04 to 2015.04 lead to freeze

Moving custom board iMX6Q from u-boot-imx 2014.04 to 2015.04 lead to freeze

[Roberto Fichera]

Hi All,

Moving my current yocto installation from fido to jethro, I've also updated my u-boot-imx v2014.04 to v2015.04.
However 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 at?

Thanks in advance,
Roberto Fichera.
