DFU Flashing - ESP32-S3-DevKitC

[meltdown03]

I see that it's supported on Arduino, but with the IDF v5, I cannot figure out how to enable DFU flashing. Running dfu-util -l shows no supported devices no matter what I've tried. Can someone please tell me which menuconfig options I need to set? Or do I have to include some code to enable it? I tried looking at how Arduino is doing it, but I can't tell how it's really working.

Do you see the USB-serial-JTAG device the S3 has? If so, you actually need to burn a fuse to switch that over to use the USB-OTG peripheral instead on bootup.

Oh, I thought there was a software method also. So I am guessing Arduino is using it in runtime so it only works after boot??

Yep.
