H,
According to the MMCSD controller user guide for the OMAP-L138 (sprufm2b), that the MMC controller supports one or more MMC/SD cards.
In section 2 it says, and I quote:
"In the MMC/SD mode, the MMC controller supports one or more MMC/SD cards. Regardless of the
number of cards connected, the MMC/SD controller selects one by using identification broadcast on the
data line"
Can you confirm if this feature is already supported in the OMAP-L138 Linux PSP release?
