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.

System Workbench for STM32

System workbench not compiling .asm files


OK, now I understand.

In the ARM world there is two different syntaxes for ASM code: the ARM (UAL) syntax (used by Keil and IAR) and the GCC syntax.

As your comment start by semicolons, obviously your file use the ARM syntax, while System Workbench fr STM32 uses the GCC syntax.

There is a few differences between both:

  • Comments are introduced by sharp # characters in GCC
  • labels must be followed by a colon : and instructions do not have (but may be) indented
  • Immediate values may be introduced by ‘#’ or ‘$’ characters
  • ...

There is a good quick-reference paper at this addressQuestion; I suggest you look at it to convert your ASM files.

Sorry to not have a quick solution for your problem,
