Hi,
wow, thanks a lot for that quick help and the suggestions, Tomi :)
I hope ED makes the right decision and at least uses lower resolution screen.
Well, I ordered 5 samples of that screen, here is my current plan:
- Let Nikolaus create a few new display PCBs for that display where we
can optionally add the Solomon Tech chip 2. Test both displays with TILER for rotation. Check cpu and battery usage as well as overall usefulness (i.e. as mentioned FireFox ignores dpi and is unusable with default settings, I will test multiple standard programs).
Assuming you mean still testing LG, I don't know how you want to test it. Tomi's fix gets rid of errors, but brings the performance even more down. As it is now it's not even fast enough to scale 320x240, OMAP5 can't even emulate megadrive with that.
The only options that may work are software rotation or shadow buffer + DMA with 1GB/s loss, but we don't even have code for that and it's unclear how to implement it.
