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

Posted by clarks on 2018-04-27 20:08

I am new to ARM developing....also new to ST....but so far I love it. I’ve been developing on an ESP32 for a year and think I may just switch to ST. I have semihosting working using the instructions under Output to debug console using GDB and it works great.

I don’t understand the other option (Output to ST Link Utility using ITM) at all. Can someone give me a high level understanding of what it does and why I might want to use it instead of GDB?
