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


Debugger just stopped working.

I’ve been using the debugger for months without a single problem.

I’m working on two cards that are communicating tegether via CAN. I swtich between the two making changes and debugging, no problem.

Today I had to go to a meeting with my computer so (carefully) unplugged the STLink and serial port.
Came back from the meeting plugged everything back in and it “times out” after bulk erase.

I checked to make sure that there aren’t any unclosed exe’s running, Reset Eclipse, re-double checked debug connections. Nothing works. I shouldn’t have to change timeout values as these worked “as is” before.

It does the same thing on both boards. I loaded the program with the serial port and it worked fine, no problem with the boards.

WTH?
