I made two of your esp32 boards. Everything works fine via usb uart, but via usb ESP always resets. Maybe you have any ideas why this is so? google didn't help. I'm attaching a video.

"*via usb uart*" and "*via usb*"?
Where does the power come from?
What does USB do?

did you use the transistors?

Yes, everything is as you made it.

Robert Feranec , 04-23-2025, 05:50 AM

did you solder down the transistor and do you control them after your board boot up?

Viktoras , 04-23-2025, 05:53 AM

I can't boot via ESP USB.

via UART USB everything is ok

Clean the board first.

that's not the problem

ah, this is the altium esp32, the transistors are on the other esp32 board. The direct USB should just work. did you measure if there is no short circuit e.g. under the esd protection? also as @QDrives mentioned try to clean the board, chemicals can sometimes inflence the signals.
