Android Pre-built Image can not boot

Can you follow this guide for flashing Android to BeagleBoneBlack eMMC?

Do you have any error log when issuing ./mkmmc-android.sh /dev/sdb ?

I am trying pre-built images.  Like this:

software-dl.ti.com/.../index_FDS.html

There are pre-built images. I wrote this image to sdcard via ./mkmmc-android.sh /dev/sdb

There is no error when  issuing ./mkmmc-android.sh /dev/sdb.

I want to ask you run the pre-built android image on beaglebone black. I hope I have hardware problem. If you run, can you write me details about beaglebone black and android version. 

Had you check the sdcard device name is correct or not (/dev/sdb) ?
Did you run the mkmmc-android.sh as root user ?
Please post any log you saw when running mkmmc-android.sh.
Did you see any LED light on the beaglebone black when power is on ?
Did you saw anything outputting from the uart for the beaglebone black when it is bootup ?

We tried the image in downloads.ti.com/.../index_FDS.html
(the BeagleBone Black one) and it does boot into Android.

Thank you for your reply.

Yes. It is correct.

I run the mkmmc-android.sh as root.

Power led light on the beaglebone black is blinked. 

I didn't see anything when it is bootup.

I tried the image  downloads.ti.com/.../index_FDS.html and it didn't boot into beaglebone black.
