It seems that only version 3 of LCD7 cape works with BBB ( 6-20-2013 kernel release and newer)
It seems that NOBODY has LCD7-XXX-03 in stock. That brings couple questions:
If V1 of LCD 7 modified to V3 ( shouldn’t be THAT difficult - couple cuts and jumps) would that be sufficient? Or EEPROM on the cape will have to be updated also? IF so is there a way to update the EEPROM?
Better yet - is there a place where V3 of LCD7 cape can be bought?

FYI
If you can live with boots from sdcard only...I have a LCD7 A2 running
here with no real problems. The only thing is, that in the very early
state of booting, the LCD shortly "flashes" (backlight in full
brigtness on/off). I am running a self compiled Gentoo and Linux
kernel 3.8.13 by Robert Nelson.
Which should *not* indicate, that any other Linux flavor with the
same kernel version will fail...
HTH!
Best regards,
mcc
Did modify the hardware to match A3 version or you tweaked the kernel to run with A2? It is my understanding that pins used on A1/A2/A3 differ…
Side question: What booting from SDCARD has anything to do with it? Whatever is result of your compile is, it can be flashed into eMMC, no?
I did not modify the hardware. See here:
