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 two short videos (registration required) highlighting:

System Workbench for STM32

Syntax error: Unterminated quoted string



The syntax error here is neither in main.c or in main.o but in the command line itself; the problem is that parentheses are someway special when using the external builder. Can you try reverting to the Internal builder?

BTW I just hecked and, on Windows, I can build successfully with the project as generated by CubeMX (that is with quotes around the value of the packed symbol) both with the internal and external builder. Looking at your traces (and especially the %CD% thing) it seems you are running on Linux; could you confirm that?

In fact here we seem to fall into one difference between the internal builder and external builder on Linux:

  • The internal builder strips one level of quotes in arguments, wherever they are located
    • -Dfoobar=”FooBar” is seen as -Dfoobar=FooBar and expanded as FooBar (an identifier) by the C compiler
    • “-Dfoobar=FooBar” is (also) seen as -Dfoobar=FooBar and expanded the same
  • The external builder will strip one level of quotes, but only if they enclose the whole parameter:
    • -Dfoobar=”FooBar” is seen as -Dfoobar=”FooBar” and expanded as “FooBar” (a character string) by the C compiler
    • “-Dfoobar=FooBar” is seen as -Dfoobar=FooBar and expanded as FoBar (an identifier) by the C compiler

The problem is that, currently, it is not possible to generate the second form in a project; thus CubeMX will probably only work using the internal builder; I will look at the problem on Linux to confirm and look for a solution there.
