How to disable JTAG?

[MalteJ]

Hi,

I want to use the JTAG pins as GPIOs.
How can I disable JTAG? Is this permanent or is it possible to reenable JTAG afterwards?

Thank you!

Best,
Malte

It looks like you can only disable JTAG while enabling Secure Boot, right?

What is the conflict you are having?

From memory, the JTAG pins are routed to the GPIOs by either the IO mux or the GPIO matrix, I don't remember which one off the top of my head. By simply reconfiguring the values in the configuration registers of that (or using an esp-idf driver, which will do this for you) you can deselect the JTAG function and use the GPIO for something else; no need to mess with fuses.
