STM32MP1 support available in SW4STM32

   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 download a short video showcasing this on the ac6-tools website (registration required).

System Workbench for STM32

Measure execution time with clock cycle counter on STM32

Add the contents of the attached System View Description to the svd for the processor you are using. Enable the CYCCNTENA in the CTRL register. Assuming the cycle count register is implemented in the MCU you are using, you are good to go :-)
