I don't think we have any easy-to-use support for burning fuses in OpenOCD. (Checking with a colleague, will come back to this if I'm wrong.) You can technically still manually burn the fuses by directly writing the eFuse registers in OpenOCD or GDB, but that's a bit fiddly.

Thanks for your reply, ESP_Sprite! Please clarify if the Espressif is planning to add such a function / tool in the near future?ESP_Sprite wrote: ↑Thu Mar 11, 2021 3:49 amI don't think we have any easy-to-use support for burning fuses in OpenOCD.
