What is the expected behavior?

Good day,
I wanted to use the example code from examples/peripherals/lcd/mipi_dsi to connect the display from the board kit ESP32-P4.
I expected the display to start without any code changes.

What is the actual behavior?

I encountered errors in serial console.

Hi @Maxim88S

If you're working with release v5.3.1, the example there is using a different MIPI LCD from the one inside the ESP32-P4-Function-EV-Board. In v5.3.2 (commin soon) this example will support the P4-Function-EV-Board out of the box.

For now, can you try the example from the master branch or from the release/v5.3 branch?

Thanks for the advice.
The master version launched without this error.
Now the output on the COM port is like this

I (1585) main_task: Started on CPU0
I (1605) esp_psram: Reserving pool of 32K of internal memory for DMA/internal allocations
I (1605) main_task: Calling app_main()

I (2025) main_task: Returned from app_main()

But at the same time, only the backlight is on, and the display itself is black. Should something be displayed on the screen when running this example and if not, can you tell me how to modify the code to display, for example, an image.

@Maxim88S Have you read the user guide of the P4-Function-Board? https://docs.espressif.com/projects/esp-dev-kits/en/latest/esp32p4/esp32-p4-function-ev-board/user_guide.htm For example, how do you connect the RST_LCD?

[Maxim88S]

Yes i read the guide. i found the solution. the code from this repository worked [https://github.com/jitenshap/esp32p4_mipi_dsi_hello_world]thanks!
