Part Number: MSPM0C1104
Tool/software:
Hello,
I am currently working on a project using the MSPM0C1104 (16-pin SOT) microcontroller and facing an issue during execution. I have configured and enabled the following peripherals in my project:
GPIOs: PA0, PA2, PA6 (Configured as outputs)
ADC: Configured and used in the application
UART: Configured for communication
I have attached my syscfg file for reference.
Issue Description
When executing my code, the program unexpectedly jumps to the function copy_zero_init. Through debugging, I have identified that this occurs immediately after the GPIO enable function inside SYSCFG_DL_init() is called. However, when I configure GPIO in a separate new project, it functions correctly, indicating that the issue is specific to my current setup.
Observations on copy_zero_init
After analyzing the copy_zero_init.c file, it seems responsible for initializing global/uninitialized variables to zero during startup. This suggests that my program might be encountering an issue that triggers this initialization unexpectedly.
Request for Assistance
Could you please provide guidance on:
Why the program execution jumps to copy_zero_init after enabling GPIOs in SYSCFG_DL_init()?
Any potential misconfigurations in the syscfg file that might be causing this?
Debugging steps to further isolate the root cause?
