I purchased MOD-SD-MMC and have connected it to UEXT on OLinuXino-Maxi (using SSP2).
Have iMX233-OLinuXino-SD Linux boot card in on board SD micro card slot (using SSP1).
How do I provision the SD card on the MOD-SD-MMC in Linux?
"fdisk -l" only shows the boot card (on board using SSP1) - not the SD card on the UEXT board (using SSP2).
Ultimately I want to access files on the second (SSP2-UEXT) SD Card but still boot from on board SD card (SSP1).

I have also tried moving the bootable SD (Linux Image) into the SD2 card slot (on the MOD-SDMMC UEXT card) and changed the Boot Mode Jumpers D01=1 (was 0) and D00=0 (was 1) to boot from SD/MMC 2 to see if the boot loader would recognize the second SD card.
In this case the board did not boot -> Just get 0x80502008 and 0x8020a01d on screen.

I noticed SSP2_DATA1 and SSP@_DATA2 are not connected through UEXT but the default for SD_BUS_WIDTH (00= 4 bit interface) in HW_OCOTP_ROM0 OTP Register.  I then connected DATA1 and DATA2 to see if that helps. It didn't help.

Has anyone used the MOD-SD-MMC? Any suggestions are appreciated.
