DRA724: QNX emmc driver,How to configure devb-sdmmc-omap_generic ,use sdmmc option

Hi Xiaobin,

The QNX User Guide that comes with the DRA72x BSP goes over how to  launch the eMMC driver and create eMMC partitions.

The below command shows one set of options to launch the devb-sdmmc-omap_generic to support eMMC.

devb-sdmmc-omap_generic sdio clk=192000000,ad  dr=0x480B4000,irq=118,hc=omap,bs=emmc:bw=8 blk cache=2M disk name=emmc

The partitions can be created/deleted/displayed with QNX fdisk, utility, some examples below.

Display current partitions:

fdisk /dev/emmc0 info

fdisk /dev/emmc0 show

Create a new 2G DOS partition:

fdisk /dev/emmc0 add -t 12 -c 0,2000
