Mangoh Yellow SD Card not working

Hi,

I am trying to mount an SD Card in the uSD slot on the mangoh yellow. I have the SD Card formatted and installed. I have SDIO_SEL2 (SW8) switched on per the HW architecture doc. I have rebooted the module. there is no mmc device showing up in /dev and i don’t see any entries in dmesg that indicated a device is being detected. hopefully i am missing something trivial to get this working.
