I am wondering if anyone knows how to get rid of programming error messages?
Example, I hit the download button to do my erase, program, verify, and if my target JTAG device is not connected an error will pop up that says, 'No JTAG Devices Found'. I'd rather not see that error window pop up. Can this be disabled?
You didn't mention the key fact that you're trying to do this from the command line! That makes all the difference.
In most cases, uVision is only calling an external utility to do downloading/programming. If that's so in your case, then could you just use the utility directly - thus avoiding uVision completely?
