after a esp_restart() thw wifi does NOT work, only power cycle
fixes this, which really screws up the developping/debbuging cycle.
is there a fix for this?
thanks,
danny

indeed, using different ttl-to-usb I managed to flash it. Had to manually
enter load mode (grounding pin 9) and now all is ok.
thanks

after much work, got esp-idf to work on a Mac running Big Sur, and
get the same error. I'm waiting to receive a esp32c3 not from M5 to see
if it has the same issues. BTW, espressif is very silent
bleeding edge of technology :-(

@felmue
thanks for the info, questions:
1- what version of idf
2- what baudrate

i CAN flash all other products as long as it's esp32, this one is esp32c3 and failes:
