For some reason, the controller disables the bus power sometime after it was enabled by the driver. The reference manual says, in Table 645, about the SD_BUS_POWER bit: > ... It will be cleared if one of the following occurs: the > sd_bus_vlt and the voltage support in the Capabilities Register 1 do > not match or if a card removal state was detected. Further investigation will be needed to find the (electrical?) root-cause of this issue.
