Bricked XIAO ESP32S3 misidentified or wrong bootloader #243
Description
I tried, a few times, to load the latest stable and last Alpha to revive a plain Seeed XIAO ESP32S3.
However it did not work.
No reprogramming works. Terminal output looks like user code, for another board.
Board info in Arduino IDE is:
DN: Unknown board
VID: 0x2886
PID: 0x0059
SN:744dbd815b8c
Can't load any code thru Arduino IDE, or VScode/Platformio/ or reflash on Meshtastic. Totally meshed up.
It is identified by Win10 as a "TinyUSB CDC" and on connection, the board starts outputting a serial data stream like a GNSS device.
