SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world.
And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download two short videos (registration required) highlighting:

System Workbench for STM32

MP1 cannot set production mode breakpoints...

on MP1 using Production mode, we cannot reliably set breakpoint in interrupt handlers.

for example, once image is loaded, we try to set a breakpoint in the SysTick handler but it never gets hit. Same behavior for other ISRs.

We’ve tried different combinations:

  • set breakpoints before launching debug
  • add an infinite loop to force firmware to wait after launch then click on Suspend and add breakpoints
  • step through init they set breakpoints
  • etc...

We sometimes get it to work, like 1/20. But if breakpoint works in interrupt, then we cannot set a breakpoint in main()

is there any limitations to Production mode breakpoints?
