HI Dmitry,
Thank you very much for your answer!
I have tried it, but I get the same:
CM-A510>> mmc init
CM-A510>> mmcinfo 0
Device: MV_SDHCI
Manufacturer ID: 0
OEM: 0
Name: Tran Speed: 0
Rd Block Len: 0
MMC version 0.0
High Capacity: No
Capacity: 0
Bus Width: 0-bit
In reference to peripherals, only is available USB and Ethernet 0 by
default. I am searching in the sources just in case there is something
else... but I am afraid I will not find something.
#define CM_A510_MPP0_7 0x00000033
#define CM_A510_MPP8_15 0x00445050
#define CM_A510_MPP16_23 0x66664040
By the way, how do you get that resgisters? In my case, I tried to
define them as per as Marvell 88AP510 Specification reference. Is it the
right place?
Best regards,
Gabriel

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,
Gabriel
