I suspect the SW is not yet in a working condition to support the cape yet…

Is it possible to install stock Angstrom linux on the Black? The changelog shows support for LCD4.

Is it possible to install stock Angstrom linux on the Black?

It is running stock angstrom linux already

The changelog shows support for LCD4.

Rudimentary LCD4 support was done last week, after the release: kernel/patches/not-capebus/0168-capes-add-basic-support-for-LCD4-capes.patch at 3.8 · beagleboard/kernel · GitHub

It looks like what was missing was the firmware files found in this patch.

Is there a simple guide on how to get this patch installed? I’ve already opkg upgrade / updated to 3.8.8.
