Moving custom board imx6q from u-boot-imx 2014.04 to 2015.04 lead to freeze

[robyf]

Hi All,

I've a working u-boot-imx 2014.04 running on a custom imx6q board. I've decided to move uboot-imx to v2015.04 for testing because I'm having some problem on getting a PCIe-to-PCI bridge working, it's a TI XIO2001. So far so good, I've migrated the board setup to the new uboot configuration and everything build straight. However as soon as I boot the board everything stops basically at relocation step. I've tried both u-boot-fslc and -imx version but all are basically freezing at similar place.

Do you have any suggestion where to look?

Thanks in advance,

Roberto Fichera.

Hello Roberto

For u-boot-2015.04,you should pay attention to something as bellow:

1)In include/configs/<board>.h, you should not use // to comment out something.

2)You should add #define CONFIG_SYS_GENERIC_BOARD to include/configs/<board>.h.

3)CONFIG_ENV_OFFSET in  include/configs/<board>.h should be larger than 400K(e.g.(8 * 64 * 1024)).

Have a great day!

Hi ZongbiaoLiao,

yes! the 3 things you listed are exactly ok in my config. I've attached my current config so you can have a look.

Cheers,

Roberto Fichera.

I've actually found that uboot doesn't returns from asm function relocate_vectors. The function board_init_f() and relocate_code is executed fine. This is within arch/arm/lib/crt0.S

Any idea?

Cheers,

Roberto Fichera.

[robyf]

Just found that uboot boot fine when removing the call to asm function relocate_vectors from arch/arm/lib/crt0.S, basically reverting back to how v2014.04 works.

Hi Roberto

had you built 3.14.52 linux images, as

uboot 2015.04 uses L3.14.52_1.1.0 kernel ?

~igor

[robyf]

Hi Igor,

no only the uboot version you suggested.

Cheers,

Roberto Fichera.

[igorpadykov]

Hi Roberto

one can printenv uboot environment variables and

compare them for both cases.

~igor

[robyf]

Hi Igor,

the code is exactly the same for both v2014.04 and v2015.04 so no env problem at all.

[igorpadykov]

Hi Roberto

please post this on uboot mail list
