[SOLVED] ESP32P4 Factory example not working (I2C) problem

[esperiment]

Hi, recently I got a P4 function board. Unfortunately, the pre-programmed factory example (brookesia) did not work: display rendered fine, but no touch..

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 attach with idf.py monitor I get the following:

The last lines repeat.

This is the same as with the pre-programmed factory example.

Is there something I can try? Thanks!

[esperiment]

Does no one have an idea or suggestion?

[esperiment]

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 series.
If I made a silly mistake, please point it out.

Thanks again.

[ESP_Sprite]

I think there's a little 6- or 8-pin header on the back of the LCD board. One of the pins is the reset for the touchscreen. Maybe connect that to +3.3V?

[esperiment]

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-ki ... requisites, that is, PWM of the LCD goes to IO26 and RST of the LCD goes to IO27 of the function board.

There is this part in the logs

Code: Select all

[WARN] [esp_brookesia_core.cpp:46](getDisplaySize): Display is not set, use default display
[INFO] [esp_brookesia_core.cpp:204](beginCore): Library version: 0.4.1

[WARN] [esp_brookesia_phone_manager.cpp:76](begin): Using default touch device(@0x0x4878a35c)

which looks suspicious.

Above that, there is

Code: Select all

en. For more detailed information, please read docs

Unfortunately, I cannot fully compare my output to the reference output from the above Github link, since that part is cut off.

Any thoughts?

Maybe you need to configure stuff in menuconfig?

[esperiment]

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 available options in menuconfig and report back.

[esperiment]

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.
