I have version 3 of the wrover dev kit. I need to set it up so that I can debug using Visual GDB, but I get this error output (see attached) when I test the connection. Visual GDB support says that it's a problem in how the device is setup/connected. How do I setup the jumpers so that Visual GDB will test successfull?

I guess I must be asking the impossible.

Have you already looked at https://docs.espressif.com/projects/esp ... it-v3.html ?

[kurtnelle]

Yes, I went through ( https://docs.espressif.com/projects/esp ... it-v3.html ) several times.

Another thing that comes to mind: what program is loaded into the ESP32? If this program redefines GPIO12-15 to do something else, JTAG won't work, and you'd get a similar error to what's in your screenshot.

" If this program redefines GPIO12-15 to do something else, JTAG won't work" -- that makes some sense. I will invoke esptool.py to erase the flash and try again. Who knows?!

[kurtnelle]

I erased the program. Same problem. Problem persists. Same screenshot. Same error message.

Just so we can double-check: any chance you can post a picture of the jumpers on your board? Also, you're sure you don't have anything else attached to the PC that openocd can see as a second jtag adapter?

Jumpers Ahoy!

...and there are no other jtag devices on the system.
