11:33:38 | ❌ Failed to flash ESP32_GENERIC_S2 on COM38
11:33:38 | ❌ No boards were flashed
- run
mpremote bootloader
--> Board reconnects to COM33 - after this it is possible to flash using the esptool cmdline adjusted to the new comport
esptool --chip esp32s2 --port COM33 -b 460800 write_flash --flash_mode keep --flash_size detect --compress 0x1000 C:\Users\josverl\Downloads\firmware\esp32\ESP32_GENERIC_S2-v1.25.0-preview.408.bin- after flashing the device reconnects as COM38 ( or COM37 ) assumably depending on the firmware details
