Hi Rova,
How did u solved it? I think it was hardware, right? Did you changed the
boot_sel0 and boot_sel1?
boot-> check fel key pressed (yes)-> check if sd0 bootable(no) -->go to fel mode
\ \
\ (yes)\__ boot from sd0
\
\ _____[00]
boot from nand flash (go to fel mode if failed)
(no) \ /_____[01]
boot from sd2 (go to fel mode if failed)
\ /
\___check boot sel[0:1]-------------------[10]
boot from emmc2 (go to fel mode if failed)
\
\______[11]
boot from spi (go to fel mode if failed)
Thanks,
Igor.
