I choose mmcsd2 to connect to WIFI chip. Compared with mmcsd0 and mmcsd1, the EDMA Events for mmcsd2 is 1&&2 but belongs to crossbar mapped. It seems that more configurations should be done to differ it from direct mapped events. But how?
Secondly, I have the driver for SD Card and eMMC, can it be used for this kind of WIFI?
Acturally, I use QNX 7.0 as the OS, if direct help for this system will be much more appreciated.
