SD/MMC2 extra storage not found by Android on A10s

[epd]

 I am running the android image found here (https://www.olimex.com/forum/index.php?topic=1439.0  ) on a microSD card in MMC1.  In SD/MMC2 I have a blank 4GB SD card, however this card is not being found by the android OS.   I have tried mounting the MMC2 card through the system settings as well as searching for it under the file browser, neither allowed me to see or mount the SD card in MMC2. 

Am I doing something incorrect? Has anyone else had this issue?
