Do you support ESP32S2？

[afterow]

Hello, does this project support ESP32S2

[polhenarejos]

Not at this moment.

But you can build the firmware yourself. Just first select esp32s2 board and build.

I flashed the Pico Fido with version 6.4, but it doesn't work properly, keeps plugging and ejecting

[polhenarejos]

It crashes on boot.

Which model of S2 do you use?
Which is the flash size?

[afterow]

My equipment is esp32-s2 mini

Do you have the chance to debug on UART0?

[afterow]

I don't know what UART0 is, but I can help you, for example through remote desktop

[polhenarejos]

It is the serial port for debugging. It requires an additional hardware like a USB-to-TTL.

[afterow]

I have a CH340B, I wonder if it can be used.

[polhenarejos]

Not sure how it works but if you know how to open a serial port it might work. Look for uart0 tx and rx pins in the datasheet of your board and probe them with your ch340b.
