ESP32 configuration on Nordic connect sdk

[fatimatayyab71]

I am trying sample application of ADC in Nordic connect sdk, an overlay file for esp32s3 is already present in it but when i select esp32s3-devkitm during build configuration it through some device tree error, could you please tell me which configuration needs to be added to resolve this issue.

Hello,

I can see a device tree error in this /zephyr/boards/xtensa/esp32s3_devkitm/esp32s3_devkitm-pinctrl.dtsi file.

Can you please check the number 14 line of this file if there is any syntex error?

I unable to identify the issue...because apparently everything seems fine....can you please check this code...

Hello,

I have talked our team. We can not help in this issue as Expressif does not use our MCU. You can ask expressif or zephyr about the ESP32 integration.
