Adding SPI MMC/SD CARD to A13-Olinuxino-micro

[mlyons1340]

Hi,
I have an SD card on an arduino like shield that I would like to use with the A13.  Unfortunately, the card is wired for SPI bus mode instead of the usual 4 bit bus mode.  I'm wondering if there is a way to make the SD card work.

In the script.fex file I see there are 3 "[mmcx_para]" configurations with an option to change the bus width.  Is there a setting for SPI mode?  If someone could point me in the right direction that would help.

Thanks,
Michael
