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

file stm32f4xx_hal_def.h is disabled

I am working my project, but I meet this issue as followed:

in my include folder, I have stm32f4xx_hal_def.h, but all contents are in grey mode, so my stm32 library files can’t use it. Does anybody know how to fix it?
