ESP8266 + SPI ST7789 DISPLAY 320x240 + I2C BME broken wifi

Hello,
I am trying to use firebeetle ESP82266 with BME280 I2C and SPI color display 320x240 with ST7789. When i compile without display and load the binary, everything works. But when i add display and i load the binary the board is not connected as you can see in the log file :

I tried many options but nothing works. Can you help me please.

did you try with ILI9xxx component?

Thanks for your answer, yes I tried with ILI9xxx plateform and ST7789V model but it doesn’t work either with the same error.

If i define just display without option (plateform and model …) that works. Perhaps ST7789V driver break wifi communication with ESP8266 core.

Once binary loaded, when esp tries to connect to homeassistant server a blue led blinks and finally stays on.

Not going to work as the display will need at a minimum around 76K of RAM, you only have around 40K free. You need to use an ESP32, preferably with PSRAM.

Hi Clyde,
I suspected a board compatibility problem.
Thanks for your answer.
