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:

Not displaying variables in the Expressions

Not displaying variables in the Expressions.
When you add a variable (eg, “period”) appears in the Expressions error - Error: Multiple errors reported \ Failed to execute MI command: -var-create - * period Error message from debugger back end:. -var-Create: unable to create variable object \ Unable to create variable object
How to see the value of a variable(“period”)?

Hi,
No way to reproduce this issue.
Are you using Windows7?
What is the SW4STM32 version?
Are you using a custom/ST board?
Are you using debug/compiler optimizations?

Hi,
Right-click on the project >> Properties >> C/C++ Build >> Settings >> Tools Settings tab >> MCU GCC Compiler >> Optimization or Debugging
Anyway, I faced the same issue.
To get the variable displayed in the Expression tab, I must remove the variable that is failing and then I add it again with the following procedure :
- Double-click on the variable in the C code to get it highlighted;
- Right-click on this highlighted variable and select “Add to Watch Expression ...”
How did you add the period variable?
