ESP32 Forum

Hi, I'm trying to get ESP32-S3-DevKitC-1 working with Arudino IDE 2.0.3. Every time with the same error message. Pressing or holding the boot button does not help.

Does anyone have a solution? Thanks!

I guess you either gave up or found the solution elsewhere. But, in case someone else comes here looking for the solution, this may be it:
You need to put it in ROM bootloader mode. If you have DFU/boot and reset buttons, hold boot. While holding boot, press and release reset. Then release boot.
