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


Run/Debug problem in SW4STM32 using ST-Link/V2 SWD

I am developing a very important application using System workbench.

I can not tell you the number of times the debugger fails to load, it is constant. Why? Who knows. Why does it start working? Who knows. It just does.

This is a HUGE problem and from what I can tell no one seems to care in the least.

When I switched to Linux I thought perhaps it would work better, nope. Still just as bad.

My release was yesterday, and I can’t fix the problem because the debugger just says “Error erasing flash with vFlashErase packet”.

What does this mean? No one knows. How do I fix it? No one knows.

I have found that to get more information click the down-arrow next to the console icon, then select the gdb traces console, or the openocd console.

The openocd console says “Error: timed out while waiting for target halted”.

What does that mean? Dunno.

This is why it is free.
