I just installed VisualGDB and I’m following the tutorial for the EK-TM4C123GXL LaunchPad. Everything works fine when I use a EK-TM4C123GXL and that’s great but my project needs to have Ethernet so I’m trying to follow the same steps to get the EK-TM4C1294XL LaunchPad working. I’ve selected the correct part in the device selection page but when I get to the debug method page I’m unable to proceed any further because no matter what settings I try OpenOCD fails to initialize debugging. I was concerned that there might be something wrong with my dev board so I downloaded the Energia IDE and that worked fine. I was able to successfully flash a program to the board using that software.
This is the output from the “Testing Settings” window of VisualGDB.

Does anyone have a recommendation on where to go from here?
