CC2340R5: cc2340 oad example not running

Part Number: CC2340R5

Tool/software:

Hi,

I am using the CC2340R5 with the basic BLE OAD example from SDK 8.10. I followed the instructions provided in the README.html on ti.com to debug the code. However, the program does not stop at any breakpoints after completing all the steps.

I set the values of SP to 0x20009000, PC to 0x2C66D, and VTOR to 0x6100.

I also tried to direct write to memory address, but it is preventing to write

Thank you.

    Hello,

    Thank you for your interest in the CC2340Rxx devices.

    I am sorry you are experiencing such issue.

    Based on the screenshot you have shared, it looks like the Flash memory expected to contain the application code (i.e. 0x6100) is blank (i.e. filled with 0xFF).

    May I kindly ask if you have changed the addresses used by default?

    Any chance the device got its flash unintentionally erased? 

    Best regards,

    Hello , 

    Thank you for your response. I am using custom board

     

    I observed that I am getting data of reset vector at memory address 0x32100. I think it will resolve my issue 

    Thank you
