Problems with ESP32 and Ili9341

Hello,

I want to use an ESP32 and ESPhome to transfer data from HA to an Ili9341.

However, the connection to HA no longer works when I integrate the display into the ESPhome.yaml.

This way the code works without error messages and the ESP connects without error messages in the LOG:

But if I now insert the minimal configuration for the display, I no longer get a connection and the following error message appears in the log.

Static texts, lines, etc. work on the display, but the connection is no longer established.

Does anyone have an idea how I can get this under control?

Thanks

I would guess you are running out of RAM. Serial logs would show more.
