Hi Peng,
Just noticed that mx6ulevk is not booting with latest U-boot:
U-Boot SPL 2016.01-rc1-00078-g736d174 (Nov 19 2015 - 13:45:19) Trying to boot from MMC spl: mmc block read error SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ###
I haven't had a chance to investigate/debug this yet.
Looks like I cannot boot using my SanDisk micro SD card. I changed the SD card and now it boots.
I can confirm you this weirdness. It depends on the SD Card, I have seen the same on a iMX6 Dual. It does not boot with industrial card (Pretec, 1Gb), no problems with "HC" cards of any size (Toshiba, Sandisk, Hama,..).
It is interesting that I do not see the problem if I don't use SPL.
For example: on a mx6qsabresd I can boot the SanDisk card without issues if I boot the mx6qbsabresd_deconfig target (u-boot.imx binary).
However, if I try booting the mx6sabresd_spl_defconfig (SPL + u-boot.img) the boot fails with the same error as I noticed on the mx6ul board.
So it seems this is is SPL MMC related problem.
Thanks,
