AartiG, thanks for the help! I reinstalled as you suggested, and I don't see the XDIAS errors.
I later ran the "Check For Updates" function, and it allowed me to get the updates for Spectrum Digital Emulators (5.2.0.08) and TI C2000 Device Support (4.1.0.4), but it also reported that "Some sites could not be found," and to get more info from an error log, but I have no idea where to look for that error log.
Importing the Example_2806xCpuTimer.out sample project, the linker reports an issue:
warning: entry-point symbol other than "_c_int00" specified: "code_start"
but I assume that I can ignore it because the processor does get to main().
I'll now find that other forum regarding the PWM problem. I've already found one issue in the sample code.
Thanks -- Mark
