I found my problem. I have two power supplies that eventually feed the power to the ESP module. There is too much bulk capacitance on the power lines when powered from USB on my PCB. This results in the ESP not seeing the requisite reset state because the 1uF cap on the EN# line charges at almost ...

I've designed a custom board using the ESP32-S3-WROOM-1 module. I've added the exact circuit using the CP2102 USB/UART interface.

esptool.py trace has the following output:

C:\work\t_baro>esptool.py --trace chip_id
esptool.py v4.8.1

Thanks for that. Helps me understand a little about how components are referenced.

I did find my problem. The code I snipped came from the generic_gpio example which creates a define in the Kconfig.projbuild file which I didn't have.

This should be very simple... I have over 30 years of embedded devlopment experience with makefiles of various flavors.

I've started with the hello_world example project from the IDF tree. Compiled and flashed it fine and it works.

Now I want to add a simple GPIO toggle LED to the same project. I ...
