  1. I tried to recompile fbtft changing colors and making same changes, without lucky. I think It's a kernel problem (spi module) and I don't see any solution by now. I'll keep you updated if there are positive news. By the way, on raspberry pi zero the same screen works like a charm up to 48mhz giving me real 60fps with same release of fbtft drivers
  2. Hi, I'm testing a clone of Waveshare 3.5" (A) TFT with the mainline kernel and I've trouble with colors With legacy kernel works very well until SPI driver hangs (see https://github.com/notro/fbtft/issues/413 for reference) due to a bug So I've decided to test it with the new kernel The TFT is attached on SPI1 and I'm able to correctly load fbtft_device (with ILI9486) and I'm able to start xorg, executing SDL & GLX application But all the colors are wrong. I've also tested bgr or mode args during modprobe without any results I attach a photo of the display running glxgears with kernel module loaded as follow modprobe fbtft_device custom name=fb_ili9486 buswidth=8 gpios=dc:18,reset:2 speed=16000000 busnum=1 rotate=0 width=320 height=480 Any suggestion? PS original glxgears colors
