IOError reading chip_id from OTP ROM of Adafruit Metro ESP32-S2 Express Beta, PID 4775 | |
--- | |
I just plugged in using my board for the first time and I'm following the instructions on this page https://learn.adafruit.com/adafruit-magtag/rom-bootloader however when I get this error: | |
[code] | |
$ esptool.py --port /dev/ttyACM0 chip_id | |

I see a similar error reported on GitHub (https://github.com/espressif/esptool/issues/333) but don't know to what extent those suggestions apply to the Adafruit board? | |
