spi ili9341 screen black after update to 5.10.60-sunxi ( fb fbtft )

[naty6458]

​ 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).

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.

fbtft history:

• v5.10.43
• v5.10.60

This patch is new in 5.10.60 and looks like it changes the reset gpio polarity: staging: fbtft: Rectify GPIO handling

Also backlight control has been broken since 5.4, fixed in 5.10.83: #571 (edit: if backlight is built as a module)

Hi First of all thank you very much. I finally managed to turn on the screen, The problem was, in the polarization of the LED pin (backlight). Before that it was on 0 when I switched it to 1 everything suddenly works. The connection to the screen worked fine, but there was no lighting to display the content :-)

The DTS file that worked for me is: (ORANGE PI ZERO)

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