Orange Pi zero 2w with waveshare 3.5inch tft

[M.E. B.]

the tft is working well on stock orangepi image but when I try the prebuilt armbian images or build it myself it look like this 
 

my dts file:

35Lcd.dts

Make sure you have ili9486.ko in your ko module folder: modinfo ili9486

 

Can you use the DTS that I published in:

https://forum.armbian.com/topic/47971-driving-the-ili9488-lcd-40-inch-cheap-chinese-clone/#findComment-208446

But change the "compatible" line with waveshare,rpi-lcd-35 ,

Delete the stuff under the "compatible" line, until the "}vsync-len = <0>;", and replace it with what you had in your DTS. Change these lines, if they are different:

                spi-max-frequency = <24000000>;
                rotate = <270>;
                bgr;
                fps = <30>;
                buswidth = <8>;
                regwidth = <16>;
