Adafruit QT-PY ESP32-C3

[devnull]

I recently received the latest batch of Adafruit QT-PY ESP32-C3 devices, they were out of stock for a while and a new batch as just been produced and shipped which I received.

I am unable to get a REPL on these new devices and suspect a Hardware problem.

The flashing process succeeds (this is the esptool.py options recommended by Adafruit)

Code: Select all

% esptool.py --chip esp32c3 --port /dev/tty.usbmodem14401 --baud 115200 --before default_reset --after hard_reset --no-stub  write_flash --flash_mode dio --flash_freq 80m 0x0 esp32c3-20220618-v1.19.1.bin

Trying to connect to REPL ^CTraceback (most recent call last):

I have repeated this procedure several times, and always get the sae result - i.e. unable to connect.

I have also tried connecting using Thonny (as recommended by Adafruit) and that wont connect either.

I don't suppose that anyone else has received this latest batch of devices and have been able to flash them with esp32c3-20220618-v1.19.1.bin and been able to connect to the REPL ?

What about the other features? Can you upload codes to the ESP32-C3?
