I purchased a Beaglebone White, along with a 7" LCD cape and 1.3MP camera, several months ago. At the time I was in the middle of a big project and didn’t have time to “play” with them. A few months later I purchased a Beaglebone Black. Same problem, no free time to work with them. Just in the last couple weeks I have found some free time and have started researching both Beaglebone boards. I plugged the 7" LCD cape into the BBW, after updating the firmware, and it worked. After looking at the compatibility matrix I then plugged the cape into my BBB, again, after updating the firmware, and without the camera. I did not work and the BBB would not boot with the cape in place. I then moved the cape back to the BBW where, now, it failed to work either.
I have been unable to get the LCD to work, after that first test, under any circumstances. Any suggestions? I can’t return it since it is several months old, even though it hasn’t been used.
I suggest you contact the people at beagleboardtoys.com for help.

Hi Terry,
You have to disable eMMC and HDMI via uEnv.txt (see commented line
there) before running the LCD7 with the Beaglebone Black if the
LCD7 is an A2 version.
If not doing so you may harm the LCD7.
You also have to prepare a sdcard to boot from.
HTH!
Best regards,
mcc
