Flashing ESP32 using ESP32-S3

[spacebiker]

Hello everyone!
I have ESP32-S3 (host) that can be flashed through USB-UART, and two ESP32 connected to host. Is it possible to flash target ESP32 using ESP32-S3 via USB-UART?
Thank you!

At least in theory, yes. ESP-IDF supports CDC as an USB class, so it should be able to talk to the virtual serial port; you could then use the esp-serial-flasher library to write a binary to it. I don't know if anyone ever tried this, though.
