I have been trying for several days now to set up debugging for esp32 boards. I have tried both an ftdi mini-module and an esp-prog board. I have changed computers and tried and tried different combinations of esp32 (pico and wroom-32) and jtag (ftdi and esp-prog) boards. This would suggest a setup error. I’ve searched the community forum. I’ve done all the usual checks. I have: checked, rechecked and re-setup the wiring numerous times and verified against several tutorials and the original datasheets. TCK - IO13, TDI-IO12, TDO - IO15, TMS - IO14; plus GND - GND; set up winusb on the ftdi and esp-prog channel 0; tried shorter cables, reduced the adapter speed etc., tried different configuration files etc; used different laptops but all to no avail, checked the debug-tool setting in platform.ini. So I am really at a loss of what to try next.
Any thoughts would be very much appreciated.
Below is a short extract of the error log:
