If you need a step by step instruction how to setup an Olimex ARM-USB-OCD-H JTAG adapter under Ubuntu Linux with Eclipse integration, please take a look at my tutorial. I've also a ready to use virtual appliance for JTAG debugging:

Did you get debugging running with these connections?

BuddyCasino,

I connected jtag as shown in diagram https://github.com/MrBuddyCasino/ESP32_ ... wiring.jpg

Could you let me know how to run openocd with this?
when I run command bin/openocd -s share/openocd/scripts -f interface/ftdi/esp32_devkitj_v1.cfg -f board/esp-wroom-32.cfg
I get error
esp32 interrupt mask on
Info : Listening on port 6666 for tcl connections
Info : Listening on port 4444 for telnet connections
Error: no device found
Error: unable to open ftdi device with vid 0403, pid 6010, description '*', serial '*' at bus location '*'
