Hi!

Would anyone have idea why spl boot fails in i2c_probe when running from
nand but not when running from mmc card or anything at all to check?

My card is am335x based board with u-boot coming from u-boot-it v2016.05.

Spl boot crashes when it tries to run i2c_probe getting timeout in
omap24.._i2c.c/wait_for_event() function. Boot enters wait_for_event() only
once, if spl boot is coming from nand and exiting with:
"Timed out in wait_for_event: status=0000
Check if pads/pull-ups of bus are properly configured",

However, if spl comes from mmc card, everything goes well, wait_for_event
is executed tens of times without problem.

All help very well appreciated!!

Thanks,
Matti
