Hi Ryan,

Card Detect is implemented over GPIO in the AM335X SDK, but I don't think there is a mechanism to control card power supply on/off.

The BBB and GP EVM both have the Card Detect signal connected to the same pin. They are identical regarding MMC0 connections too the SD Card cage. So if the GP EVM supports this then BBB should support it too.
