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:

Hi thanks for Your help!

During my investigations in the code I found following code lines:

  • #ifdef GNUC
  • /* With GCC/RAISONANCE, small printf (option LD Linker->Libraries->Small printf
  • set to ‘Yes’) calls __io_putchar() */
  • #define PUTCHAR_PROTOTYPE int __io_putchar(int ch)
  • #else
  • #define PUTCHAR_PROTOTYPE int fputc(int ch, FILE *f)
  • #endif /* GNUC */


Can You help how to set this option “LD Linker->Libraries->Small printf
set to ‘Yes”?

Maybe this will solve my problem?

PS: “GNUC” where should be defined - there where other symbols?
Project -> properties -> C/C++ General -> Paths and Symbols -> Symbols?
