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:

Re: STM32F446V support

Yes, SW4STM32 supports STM32F446 mcus and STM32446E-EVAL board. Are you using this board ? It looks like there is an issue with power supply. Did you change the default position of the jumpers ?

Best Regards,


Thanks for hint, anyhow it is not STM32446EVAL!

I was using 3pin SWO connection and the problem was lack of MCU power on STLINKV2. Connecting pin1 to pin19 of 20 pin JTAG fixed it.
