While setting up a JTAG target in CCS V5.1.1.00033, clicking on the "Test Connection" button gives a "file not found" error. It's looking for a file named "dbgjtag.exe", which is the wrong name for a Linux system. There exists an executable file named "dbgjtag" in the same directory it's searching.
Creating a symlink from "dbgjtag.exe" to the "dbgjtag" file gives satisfactory results, so this appears to be a file name issue rather than a missing file.
