Re: TFT screen working under Linux framebuffer driver

Hi,

I followed the fbtft directions given by dferyance.  I used the adafruit 2.8 but unlike his original post I used BSP 1.0.  But I had a persistent -12 error which I traced to dma_alloc_coherent() call in fbtft-core.c (line824).  The only way I could get past the error was to modprobe fbtft with dma=0.  After that the screen could update.

 

Anyone have any suggestions?

 

Also having trouble getting usb keyboard working...
