I am using freedom e300 arty devkit with a Sifive openocd on an Arduino 1. Although OpenOCD can be configured to use Raspberry Pi as a JTAG debugger, it will be relatively slow (due to various latencies) and unreliable. Example of invoking OpenOCD build locally from sources: Based tny work initiated within the GA Ejtag tiny tools School of Electrical and Computer Engineering, a new engine has been developed which removes the tedium normally associated with the use of boundary scan. Those pins are used for JTAG communication. SWD is a more modern version of JTAG and only requires 2 pins instead of 4[+1].

Re: please help to get JTAG working on esp wrover kit Post by ESP_Sprite » Thu Mar 16, 2017 4:25 am The esp-wrover kit needs jumpers on all but the outer two positions of the header closest to the reset button for jtag to work.

If you are using OpenOCD, please read this additional information. Another point to note is that in some circumstances the OpenOCD executable is not stopped and retains control of the JTAG device preventing you from downloading a new image or starting a debug session.
