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:

ST-link printf to console with GDB and semihosting or ITM and ST Link Utility

Hi, please can you explaine how to activate the SWO without passing by CubeMX, by adding the code responsible for this manually.
EDIT:
So i stalled with the semihosting and i get it to work in SWSTM32 on stm32f407biggrinbiggrinbiggrin:
-First you dont need to add the serial wire from cubemx if you need a cubemx project (for me a default project just activate the semihosting without more confugiration).
-If you dont need to use a cubemx project you just need to do the steps as described above(1-5) then delete all the function in syscalls.c which make errors then delete the “int _write(int file, char *ptr, int len)” and then the semihosting is working.
