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 (registration required) various documents highlighting:

System Workbench for STM32


Hi,

Can you verify the project optimization and debugging settings ?

Go to the project properties > C/C++ Build > Settings > Tool Settings

In Optimization : set the optimization level to “None (-O0)”
In Debugging : set the debug level to “Maximum (-g3)”

Hope it is where the problem comes from.
Kevin.


Hi Kevin,

thank you for your answer. I’ve just checked and they are exactly the same. So this is not the problem. Any other suggestions?


Hi,

I think it’s working now. It doesn’t jump to the interrupt handler, but at least it doesn’t jump to the wrong line either. So it’s looking good. I just need to find out why the interrupt is not working, though it’s working for Keil uVision, but that’s another topic. The problem was that in the optimization the tags Place the function in their own section and place the data in their own section was checked. Unchecking seems to fixed. Thanks for the support.


Something is wrong with the previous answers.

The optimization option (-O) has a number (0-3). As the number increases, the optimization that the compiler does increases.

When debugging, you want to turn the optimization off (-O0).

When you release your code you want to test and release with higher levels of optimization (-O3).

If your toolchain is set with debug set to 3 and release set to 0, that’s just wrong.
