    OpenOCD Debug Issue

      I have the EZ-USB FX3 DVK. I am trying to debug it using the Cypress EZ USB Suite, and an Olimex ARM-USB-OCD-H.


      I followed the instructions in the EZ-USB Suite Users Guide for using OpenOCD to debug. When ever I try to debug in the IDE I recieve the following error:


      Open On-Chip Debugger 0.8.0 (2014-12-03-15:43)

      I've tried using a different config file, which I found on this site, and using the Olimex supplied openocd.exe, but nothing seems to work.


      Can anyone help me out with this? I'm running out of ideas.

          OK, I mostly have it working. I switched over to using the Olimex openocd.exe. I'm not sure if that matters. I also specify a different config file, and olimex-arm-ocd-h.cfg in the config options:


          And I had to alter the config file I found. There was a -variant switch in the file that wasn't valid. I'm not sure what the original author was trying to do, but I just removed the switch, and it seems to work.


          Now I have one more issue.


          I have "Start OpenOCD locally" checked, but it doesn't start it locally. I have to use the command line to start openocd.exe with the proper options, and leave it running in the command window. Then I can go back to the IDE, and debug.


          Does anyone know how I can get the IDE to start openocd.exe for me when I begin a debug session?
