[SOLVED] Waveshare 5" DSI - Touch does not work -

[Tim Curtis]

With the MoOde 8.3.9 version, the Waveshare DS1 5" screen works normally, while with the new version of MoOde 9, the screen activates, but without the Touch functionality. Everything else seems to work well apart from some difficulties in setting the WIFI network if set in STATIC. In DHCP mode, the connection occurs quite quickly. However, I will check the parameters of my internet network as it could depend on my configuration and not on the new MoOde 9 even if everything worked without problems with the previous version. Furthermore, the backlight is very dim compared to the previous build.

I'll answer myself, I found the solution for the non-recognition of the touchscreen.

In /boot/firmware/config.txt you need to add the following line dtoverlay=rpi-ft5406 after dtoverlay=vc4-kms-v3d. The touch screen returns to working normally.

Nice find. What link had that info?
