A-P Posted July 29, 2017 Share Posted July 29, 2017 Hi, I'm using fbtft with legacy kernel in orange pi zero to be able to use 3.5 inch raspberry LCD with ILI9486 (not sure). Everything works and I can get image from the LCD (although it is terribly slow). But I have one big problem. LCD freezes after some time or when screen screen changes or even sometimes during initialization . Is there anything wrong with the spi driver in armbian ? How can I get over this issue ? I'm sure there is nothing wrong with the lcd because I have tested same lcd on raspberry pi and I have about 500 of these lcds for a project. This is the my fbtft options : modprobe fbtft_device custom name=fb_ili9486 gpios=dc:18,reset:2 busnum=1 speed=8000000 txbuflen=32768 rotate=270 fps=1 Link to comment Share on other sites More sharing options...

A-P Posted August 19, 2017 Author Share Posted August 19, 2017 By changing fps to a higher number frequency of hanging increases a lot. that why we set it to one and as we only use the lcd as a static notification viewer it makes no problem. But hanging and freezing is the problem. I somehow think that the main problem is due to the buggy X server because even when lcd freezes if we kill X process lcd gets back to work. Any suggestions ?
