MSPM0L1306: Hardware reset issue

Can you ask customer to measure the Rst pin signal and VCC signal, then post it to this thread.

What do you mean with "not running properly". Not run at all or the code performance is not right?

Hi Eason, 

The code runs but stopped as shown in the following picture.

Seems like customer found that after forcing to fix  BSL_invoke level to LOW, the MCU running properly now.

So I proposed them to set the setting of BSL invoke logic to LOW by using sysconfig, but by doing that it is said on the debugger tools IAR that "Failed to connect to CPU. " 

Do you have any suggestions on these? 

Best regards,

Kenley

I would suggest you disable the BSL and make a try:https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1435856/mspm0l1306-wdt-operation-is-different-between-launchpad-and-prototype-board

If you want to set the BSL invoke pin level to be low. Please make sure normally the PA0 voltage level is high.

Hi Eason,

Customer is considering to disable the BSL and due to the BSL configuration is changing the NON-MAIN memory region.

Does the output file (hex/mot file) also include the NonMain region setting? 

Best regards,

Kenley

Yes. It will contain NonMain region
