I seem to be having difficulty getting a just purchased BeagleBone Black and BB 7" Touchscreen display to work. I wonder if someone could give some help.
Followed the hardware installation instructions in the manual, which are easy enough. After fiddling around with Debian, in which I could get HDMI OK and all else seemed to work fine, Went looking for the TI Angstrom demo. After working through the Element14 links I dug BBB-eMMC-flasher-2013.09.04.img out from BeagleBoard.org - latest-images. I am still presented with a blank screen. Is this the correct image?
It shows the cape not being recognised.

Followed instructions in the BB-View Cape user manual with no effect (the images suggested are actually a later date than the latest images from beagleboard.org, but cannot find them on Element14's site).
Back to Debian. After updating the kernel as suggested in the Debian Howto, and setting in uEnv.txt:
optargs=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN capemgr.enable_partno=BB-VIEW-LCD7-01
got the same result - cape not recognised, similar to here .
That seems to be the end of my competence. Any suggestions?
