ESP32 C6 Development Board Bootloader Issues

2026-04-18 13:30:03 Ask

I can't seem to get an ESP32 C6 Development Board into Bootloader mode.

I think it keeps running a program I uploaded instead.

Is there a failsafe way to start the bootloader?

Error is:

Serial port COM4:

Connecting....

A serial exception error occurred: Write timeout

Press and hold the boot button

Insert USB power supply

Then release the boot button.

Afterwards, the main control will enter firmware update mode
