Hello, 

 

i update my OrangePiZero OS from Linux 5.10.43-sunxi to Linux 5.10.60-sunxi
my screen fbtft spi lcd stop working , the screen is black.

If there is a solution to this issue I would love to get help, thanks!
here my configuration (work on 5.10.43).

 

(Armbianmonitor link of 5.10.43 on top)

(Armbianmonitor link of 5.10.60 Attached as a file )

Thanks to notro notro I solved the problem, changed the way the screen brightness was controlled.
Here is the configuration I have at the moment.

reset ---> PA7
led ---> PA6
dc ----> PA2
