Suitable JTAG for ESP32

Postby Kp_Devil » Tue May 15, 2018 3:58 pm

Hey Guys,
I want to debug my ESP32 program, so can you please suggest any specific JTAG that will work for sure.
(In docs it says "JTAG with voltage level same as esp32", but how to find them?)
Please suggest multiple option as I will have to choose which one is available in my area.
Thanks in Advance.

Personally, I am not a JTAG fan, never needed more than a simple printf.
That being said, I can tell you that the following does work just fine for the ESP32.

Thanks for the quick response, but both of them is not available in my area.
Any specific properties my JTAG should have so that it can be used to debug esp32.
So that I can find an alternate in my area.
Thanks for helping me out guys, really appreciate your efforts.

I have one of these, from Amazon, and it works with the blink example from Espressif:

I posted the commands for Openocd on this forum recently.

You can also get a wrover kit for $40. I think electrodragon and olimex ship world-wide so unless you are in a hurry...
