Hi everyone,
I am trying to program the FE310 target board through OpenOCD. Unfortunately I have only been able to do so two times (randomly). All my other attempts have resulted in errors. I am using the Chipwhisperer Lite with the CW308 UFO Target board and the FE310 victim board. I have followed the instructions from the following tutorial. Furthermore, I have tried supplying power to the victim from both the capture board and an external DC source. I have also tried multiple different OpenOCD versions.
An example of an error occuring when I run run_openocd.sh script with the “fe310.cfg” file:
Setting up MPSSE mode... Done

I get this output for both of my FE310 victims.
My target board is configured as follows:
I wish I could add more pictures, but I can’t since I am a new user of the forum. I hope that the JTAG wiring is clear from the picture.
The switches have been set to deliver 1.8V and 3.3V from the External DC source to the Victim Board.
Here is also a snippet of the output of OpenOCD with the debug flag enabled:

I am guessing that the issue is related to hardware and not software. Maybe I am doing something wrong with the wiring or the issue lies elsewhere. I hope that maybe one of you can aid me in figuring out what exactly is causing this issue.
Thanks in advance!
