ESP32-S2 2nd usb-serial port
HI
At micropython for ESP32-S2, I'd like to have
secondary USB-serial port (like /dev/ttyACM1 on linux)
which directly maps to board's hardware serial port
RX/TX pins and if possible, few RS232 signaling lines.
Can this (easily) be done?
REPL on Espressif ESP32-S2 board appears on wrong USB port
I flashed the generic ESP32-S2 firmware to this Espressif board. The board uses a UART-USB bridge to provide USB connectivity. Component placements to provide the internal USB interface are not populated.
Flashing was successful. On reset, the board's USB port emits debug information but no REPL. In this forum thread user ash10 explained that the REPL appears on the built-in software USB port on GPIO19-20. It seems that the board could be used by connecting a USB breakout to those pins (waiting for hardware to try this). This seems clunky.
I had naively assumed that the Espressif board would be a reference board as per ESP32. Is support for this board planned?
