Hello,
I am trying to boot the kernel image from SD-CARD (mmc0) in the CM-510 SoM(provided by Compulab) using the u-boot image provided by Compulab:
http://www.compulab.co.il/products/computer-on-modules/cm-a510/#devres
By default, it seems SD-Card is not enabled, so I think I have to configure right the MPP option.
I have searched over and over in the code sources, I have change some arrays defined in some files that are related to the MPP (pinmux) but nothing happens:
./board/marvell/mv_dove/dove_family/boardEnv/mvBoardEnvSpec.h:

Anyone has faced this problem before? I really appreciate some kind of help.
Best regards,
