OK, I searched the issues on Github and found https://github.com/espressif/esp-dev-kits/issues/115

The suggestion was to connect the camera because a component had changed.
With the camera connected the example works now.

Maybe you need to configure stuff in menuconfig? Indeed, the reason for my self-compilation failures could be missed configurations. I'll have a look at relevant options. But this does not explain the initial (i.e. factory programmed) example failure of the I2C/touch events. Still, I'll check avail...

Thanks for the suggestion. I tried, but sadly there were no changes, i.e. display is on but no touch events go through. There is wiring done according to https://github.com/espressif/esp-dev-kits/tree/master/examples/esp32-p4-function-ev-board/examples/esp_brookesia_phone#prerequisites , that is, PW...

Can maybe someone from Espressif shed some light on this? As I wrote initially, the factory example did not work properly, i.e. no touch events. I assume that this is not supposed to happen? I get that my recompilation attempts are my own responsibility, but I'm not very experienced with the ESP32 s...

Does no one have an idea or suggestion?

Then I updated IDF (I'm on f420609c33 now, with Win11) and tried to compile the examples myself to see if that would help. It didn't :( When I att...
