Debug and flash program ESP32-S3-WROOM-1

Postby orbitcoms » Thu Jul 27, 2023 7:30 am

Is only a single USB port required donnected to D+ and D- of ESP32-S3-WROOM-1 for both jTag debugging and flash programming?
I assume a push button needs to be added to boot pin to put into program mode for flash programming?

Any information about the debugging and flash program wiring required will be much appreciated.

Yes. It's advised to have a boot button (or other access method) on GPIO0 in case somehow the USB-serial-JTAG port gets accidentally disabled in firmware, but this is mostly something that is useful to have in case of an emergency, not something you'd use every time you flash the device.

Thank you for your reply.

I am about to lay up a printed circuit board and need to make sure I have the correct connections.
