Zephyr project on STM32

   Zephyr Workbench, a VSCode extension to manage Zephyr on STM32.
It enables users to easily create, develop, and debug Zephyr applications.
Main features:
  • Install host dependencies.
  • Import toolchain and SDK.
  • Create, configure, build and manage apps.
  • Debug STM32.
You can directly download it from the VSCode marketplace

SysTick_Handler doesn't trig under Debug mode

Hi,

In this case it seems that this is a bug in STM32-MAT/TARGET code generator. I can’t really give more advise on this (not knowing the code where this variable is used) but if volatile is needed there, that probably means the variable is tested (in a loop?) while it is modified in another piece of code (probably some kind of interrupt).

I presume that when you said SysTick_Handler is not invoked you mean that your SysTick-dependent code is not executed but the handler is correctly invoked, writing this variable that is checked in the main loop.

I can’t check as I don’t own Matlab/Simulink Software, but you should probably notify the STM32-MAT/TARGET development team of this problem; I think the System Workbench for STM32 toolchain is more aggressively optimizing the code, so the need for the volatile declaration, but there may be other places where the code generated by STM32-MAT/TARGET may need to be corrected.
