Hello,

I am experiencing issues when attempting to flash an ESP32-C5 dev kit ()ESP32-C5-Devkit-1 V1.2 using the IDF command line tools.

The applications build correctly but always fails of be flashed. Debug details below and would greatly appreciate any help to resolve this issue.

Espressif --- would request your support on getting started with your latest dual band wi-fi solution. As the board was pre-programmed with the blink app then there is a solution for flashing the devkit. Please advise.

You're probably using a version of the chip that is not supported by the ESP-IDF version... maybe you can try the master branch?

I have followed the advice available online to use the master branch, also for the esp32c5 to use the --preview flag but the results are the same.

same err
same board
same prompt

Where did you buy it?

I am having exactly the same problem, it looks like the IDF isn't compatible with the production silicon.
