ESP32-S3 JTAG debugging

[Padure]

Hi,
I'm trying to route the internal JTAG interface through an external uart to USB interface which connects to the U0TX and RX pins (like a CP2102). The goal is to be able to use jtag debugging using 2 pins instead of the typical 4 pins, however without using the internal USB PHY. Is this possible and if so how can I do it?

Thanks

No, sorry. Either you can use USB-serial-JTAG with an internal or possibly external USB PHY, or you can use the 'raw' four-wire JTAG bus.
