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:

System Workbench for STM32

Unable to install Cube HAL in firmware configuration.

Firmware installer just keeps restarting. I’ve waited 3 hours or so for it to finish and it has not done so. This is unbelievably annoying that Eclipse sucks so much.

It gets about halfway through 256mb and restarts.

Not sure what to do now. About to give up on this terrible software system and move on to something else.
