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:

How to output SWO trace?


Hello Nevets,

Thank you for the tip biggrin

I have tried this using an STM32F429I-DISC1 (after soldering the SB9).
My program print status a message every 1 second (visualized using ST-Link Utility > Printf via SWO Viewer)

but even after adding the tpiu config nothing apprears
tpiu config external uart off 180000000 1800000
# cpu frequency is 180MHz and the adapter speed is 1.8MHz

Any Idea ?

I have added (itm port 0 on) before the tpiu config, and modified the tpiu config as following:
tpiu config internal swo.log uart off 180000000 1800000
=> Now I have some output in swo.log file
But I cannot display the SWO data in eclipse.
