[OMAP-L138] Using MMCSD1 for SD card and TiWi interface

GrantHatamosa

Hi,


We are planning to connect an SD card reader and the TiWi module on the MMCSD1 interface at the same time.

Is  this even possible? Can we run a Linux driver that can control one at a time while they are sharing hte same bus?


Our other option is to connect a digital multiplexer on the MMCSD1 interface so we can toggle from one to the other whichever is needed.
