Hi, in preparation for the next hardware version (expected to be with TILER and without ssd2858), I have updated the device tree file names a little.
We now have two major Pyra device tree binaries:
a) omap5-letux-cortex15+pyra.dtb expects a display board with ssd2858 rotator chip and BOE panel that will be programmed through the panel-mipi-debug driver by the /root/ssd2858 script
b) new: omap5-letux-cortex15-v5.1+pyra-v5.1.dtb expects a display board with bridged ssd2858, i.e. a non-rotating board to use the TILER for rotation. It directly probes the boe-w677l panel driver and does not need a shell script to start.
Despite its name currently also works on the 5.0 prototype boards (but this may change. Hence the differentiating name scheme).
There are some other pyra related .dtb files but you can ignore them since they are for my hardware experiments and old prototypes and will be retired in the future.
How to use: either edit uEnv.txt on the boot partition or rename/copy the file so that it has the default name "omap5-letux-cortex15+pyra.dtb"
