[OMAP-L137] SDCard and EMIFA usage

Andreas Jahn

Other Parts Discussed in Thread: OMAP-L137

Hi,

I have to use a SDCard and the EMIFA (for memory mapped devices/chips) in my OMAP-L137 application.

According to SPRS563E several EMIFA pins are multiplexed with the MMC/SD peripheral of the L137.

Does somebody knows a solution how to use a SDCard and several memory mapped devices connected to EMIFA 'at the same time'?

BR,

Andreas

Hi Andreas

Unfortunately since the SD/MMC pins and EMIFA IOs are mux'd you will not be able to use them "simultaneously"

Depends. If you willing to lose EMIF address A0, A1 and data D0-D3 lines to the SD Card, you can use EMIFA and SD Card at the same time.
