CCS/LAUNCHXL-F280049C: Break at address "0x3fc7a5" with no debug information available

Part Number: LAUNCHXL-F280049C
Other Parts Discussed in Thread: C2000WARE

Tool/software: Code Composer Studio

Hello,

I recently purchased the LAUNCHXL-F280049C and have been having some significant trouble getting it to operate. Thus far, I have not been able to load any operational code to the device. I am attempting to upload a sample program (specifically "led_ex1_blinky") provided in the C2000Ware. Originally I was having trouble even connecting to the device debugger but was able to correct the problem following the instructions given here. Now I am able to connect to the device and I think I am uploading code, but as soon as the debugger begins it immediately jumps to address "0x3fc7a5" and displays the message "Break at address "0x3fc7a5" with no debug information available, or outside of program code." Allowing the program to resume drops the code at address "0x3fb02a" which contains an ESTOP0 opcode, halting the program. 

This same thing happens regardless of what program I run, and no changes to the source code produces a different result. Perhaps there is simply a hardware failure on the board, but I want to see if there is a potential solution before I seek out a replacement. 

Please let me know if you need any additional information or clarification.

    Hi Russel,

    The addresses you specified are somewhere in ROM code.  Either the program never loaded or the program reset for some reason or had an illegal ISR or was stuck running boot-ROM.  Here is a roughly step-by-step procedure to load your .out file:

    (precondition: code compiles and generates a .out file)

    When you click 'load program' you should be able to select your .out file via a file browser.  It should load the code and set the PC to the beginning of main.  From there you should be able to hit the green 'play' button to run the code or use the single-step buttons to step the code.     

    Note that you don't need to create a new target config each time.  Just launch the config, connect the core, load the .out, and then run the code.  

    Once everything is setup it'll also ask you if you want to automatically re-load the code each time you successfully compile a changed program.
