Boot Android 4.2.2 on BlackBone Black emmc device without MicroSD card issue

I used emmc fastboot to flash MLO, u-boot, bootimg, system.img, userdata.img and cache.img into internal emmc. Is any other file should be modify? I always got a error message “fs_mgr: Cannot mount filesystem on /dev/block/mmcblk0p3 at /data”. How can I fix this issue when I want to boot the android from emmc device?

Check your init.am335xevm.rc, fstab.am335xevm and vold.fstab for any references to /dev/block/mmcblk0pX. Files in rowboat assume mmcblk0 as the sdcard device. BBB emmc is mmcblk1, you need to edit the files to fix the sdcard path before flashing.
