Hi Calvin,
Thanks for the information, but correct me if I'm wrong but these resources seem more concerned with something being wrong with the physical board? I haven't done the online course though yet. However, When using another project I can program and run the board fine. And I tried running the current project on a different board and it still fails. I'm not sure why but after attempting to program the board. The SOCVHPS disappears from the device chain. And only the 5CSEMA4U23 remains. So when it tries to access the JTAG chain it expects two devices but only finds one.
