Part Number: TMS320F28P550SJ
Other Parts Discussed in Thread: C2000WARE

Tool/software:

Hello,

I am facing an issue where in my program builds succesfully however, when I try to flash it/ launch a debug session, I get the following error. 

After flashing the device, the MCU becomes completely unresponsive and locked. It stops responding to any debug or communication attempts. Once locked, I cannot flash any other code to the device, including the recovery firmware.

Please help out with this issue.

Thank you!

    Hello, please follow the below steps to get the device out of the locked state.

    • Enter into Wait Boot Mode 

      Put the device in Wait Boot mode ( S3 = 0 ) by changing the switch position on the board. 

                

    • Find Target configurations

      In your CCS Window, go to View -> Target Configurations  

                

    • Enter Debug Mode

                1. In Target Configurations, navigate to "Projects" and locate your project (for example mine is called empty_driverlib_project)

                2. Expand the folder and right-click the LaunchPad target configuration (.ccxml file) . Select “Launch Selected Configuration”

                

                 3. Right click the first option in the debug window that pops up and select “Connect Target” 

                 

    • Go to On-Chip Flash Plugin

      Navigate to Tools > On-Chip Flash. If the “Tools” dropdown doesn’t show up, ensure that you’re in the CCS Debug editor 

                

    • Erase settings

      Scroll down in the On-Chip Flash tool and confirm the “Erase Settings” are the same as below

                 

    • Erase Flash

      Click on Erase Flash

                

    After you have done this, try importing a generic example from C2000Ware (for example C2000Ware_5_05_00_00\driverlib\f28p55x\examples\empty_projects). Flash the program to the device and see if you're able to launch a debug session. The device should not be locked anymore and the program should be able to run as normal. 

    Thank You!
