Start by reproducing the make TARGET_PRODUCT=beagleboneblack OMAPES=4.x -j sdcard_build flow and installing the image with mkmmc-android.sh on the BeagleBone Black. Use adb to inspect the running system while the display shows only the top bar and notification. Done means the device reaches the normal lock screen like the TI 4.2.2 prebuilt image.
