Hi Shankari G,

These are error details along with the EVM.

I don't know why the load program failed every time.

please give us a resolution on it.

Krishn Singh Chauhan,

Before you load the sample c code program, you have to load and run the gel file which does all the initialization sequence.

--

Steps:-

1. create and do Test Target Configuration - Test connection should be successful before moving to next step.

2.  Load and Run GEL File - Observe the out put messages of initialization sequence in the CCS console 

3. Load the sample .out such as Platform_test, uart code etc.

After the Step 1 & 2 are performed.

Another error generated When We debugged the program this error displayed in the console.

Krishn Singh Chauhan,

Glad to hear that your problem is resolved.

Post your resolution, so that other forum members also can use it if they step into the same problem.

Did you miss  any step in the Quick start Guide? or missed any memory map file like .cmd?  while loading the .out file....
