LP-MSPM0L1306: bsl_spi_flash_interface example Attempting NONMAIN write without erasing

LP-MSPM0L1306: Can't load UART SBL example (Error -614)

Tool/software:

Hi M0 team, 

I'm attempting to use the secondary_bsl_uart example from the M0 SDK onto an MPSM0G3507 launchpad, but am encountering the following issue.

Using the following thread, I was able to change the Debugger to allow erasing of NONMAIN before writing.

https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1318281/lp-mspm0l1306-bsl_spi_flash_interface-example-attempting-nonmain-write-without-erasing

However, debugging now causes a new error: 

From this point i have to factory reset the board with the following tool, which allows me to at least connect to the target.

However, repeated attempts to load through the debugger continue to fail. Any thoughts?

    Hi, 

    1. Try to recover your device first, after factory reset, try to download a simple demo such as gpio toggle output to confirm that device is work normally.

    2. Please follow the following suggestions to do recovery.

    Hi Helic, 

    I was able to flash the device with a GPIO toggle command and everything worked fine. Attempting to re-flash with secondary_bsl_uart still results in the same error. I was able to note this time around that the first error I get is as follows: 

    CORTEX_M0P: Error: (Error -1001 @ 0x0) Requested operation is not supported on this device. (Emulation package 12.7.0.00105)

    Some more e2e searches reveal that this could be an issue with a support package (similar to this thread)

    However the recommended fix (updating CCS through the help > check for updates tab and rebooting) didn't update the Emulation package and did not solve this issue.

    Hi, 

    From my side, CCS Help - About Code composer Studio - Installation Details

    My TI Emulators version is 12.7.0.00130.

    You can try update this independently by clicking Update..

    I also try these two secondary BSL demo, there is no issue.

    By the way, which device are you using? I can see LP-MSPM0L1306 and LP-MSPM0G3507 on this thread's title and text.

    Please select the right device examples from SDK:

    C:\ti\mspm0_sdk_2_01_00_03\examples\nortos\LP_MSPM0G3507\bsl

    C:\ti\mspm0_sdk_2_01_00_03\examples\nortos\LP_MSPM0L1306\bsl

    Regards,

    Helic

    Hi Helic, 

    Sorry for the naming on the thread - I am using an MSPM0G3507 launchpad and using the example C:\ti\mspm0_sdk_2_01_00_03\examples\nortos\LP_MSPM0G3507\bsl\secondary_bsl_uart`.

    I just updated my CCS again, and my emulation package updated to 12.8.0.00189. I also re-imported the example from the SDK. However, I am still getting the same error when I attempt to flash the Secondary Bootloader example. 

    All the best, 

    Ethan Cope

    Hi, 

    This is normal phenomenon.

    Because secondary BSL code start from 0x1000, instead of 0x0000 (default).

    For secondary BSL test, please follow the readme file.

    Regards,
