Compiler/CC2640: Exception occurred at debugging

Part Number: CC2640
Other Parts Discussed in Thread: CC2650

Tool/software: TI C/C++ Compiler

Hello,

I'm using cc2650 launchpad as a debugger for a cc2640, when running my project it will stuck in an exception:

Initially this project works on cc2650. CC2640 is connected to launchpad via jtag connectors to xds110.  (as in this image) 

Thank you!

    Hi Matei,

    Could you give us more details on how to reproduce this set up? Is this a custom board, are you using 2.2.1? Does this problem occur flashing a simple project? (Simple Peripheral for example)

    Hi,

    I'm using a custom board and trying to flash project zero, with some modifications, nothing changed in the stack project. SDK version is 2.2.1

    Hi Matei,

    This sounds like it is likely a configuration issue with running your firmware image on custom hardware. These are usually related to board configuration and pin config.

    A couple of questions to help us debug:

    1. Does your custom project work without issue on a CC2650LP?

    2. Did you modify the board file?

    3. Have you changed anything related to RF front end?

    A few suggestions:

    1. Limit all GPIO acces in your application, comment out any calls to drivers or pins. Terminate all GPIOs

    const PIN_Config BoardGpioInitTable[] = {

    PIN_TERMINATE
};

    2. Attempt to boot your custom board using the limited configuration described above. it should work successfully. The BLE stack requires no GPIOs.

    Problem solved. It seems that in my custom board I had SCL on DIO_5 and SDA on DIO_4, which is wrong.
