MIPI DSI Touchscreen support (waveshare 800x480)

[provalinf]

Hi,
I have a screen like this https://www.waveshare.com/wiki/4.3inch_DSI_LCD
That I can't get to work with the tinker board 2 (black screen).

linaro@linaro-alip:~$ dmesg | grep ili9
[    2.041912] tinker-mcu: tinker_mcu_ili9881c_probe: address = 0x36
[    2.048018] tinker-mcu: tinker_mcu_ili9881c_probe: i2c_id= 0x8
[    2.099652] tinker-mcu: tinker_mcu_ili9881c_probe: init_cmd_check[-6] failed, 0

linaro@linaro-alip:~$ dmesg | grep 5406
[    6.125932] tinker-ft5406: tinker_ft5406_probe: address = 0x38
[    6.131786] tinker-ft5406: tinker_ft5406_probe: touch is on DSI-0
[    6.647442] tinker-ft5406: tinker_ft5406_probe: wait connected timeout

If you have a solution to this, I'm interested.
Thank you!

hello @provalinf ,
this panel is not on the official qualified vendor list, but we can do basic checkings. can you send us 1. a pic of your board connected to the panel with the fpc cable 2. complete logs?
