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.

I’m not sure if I have the same root cause of the problem as others in this thread, but I had the exact issue as the OP and solved mine by temporarily pausing my antivirus software. They are apparently on a hair trigger these days. I had a similar problem recently with a device driver installation and found that the AV software was deleting files as soon as they were unzipped without even giving any kind of message about that. YMMV.
