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:

System Workbench for STM32


using openocd read

Hello everbody,

i try to get a clear with the openocd.
For the openocd i use the System workbench Configurations and Scripts.

To open the Debugger i use:
~/Ac6/SystemWorkbech/plugins/fr.ac6.mcu.externaltools.openocd.linux64_1.23.0.201904120827/tools/openocd/bin/openocd -f Program.cfg -s ~/Ac6/SystemWorkbech/plugins/fr.ac6.mcu.debug_2.5.0.201904120827/resources/openocd/st_scripts

  • {On-Chip Debuger 0.10.0+dev-0021-g524e8c8 (2019-04-12-08:33)}
  • {STLINK v2 JTAG v29 API v2 SWIM v7 VID 0x0483 PID 0x3748}
  • {target voltage: 3.188976}
  • {Unable to match requested speed 8000 kHz, using 4000 kHz}


Then i log on with telnet:
“telnet localhost 4444”

then i make the init
“reset init”

So far so good. Now i want to read a address. When i read the “openocd User’s guide” there is a command to read: “flash mdw addressNbr”
http://openocd.org/doc/html/Flash-Commands.htmlQuestion

but when i try to use this command(“flash mdw 134217744”) openocd tell me “invalid subcommand mdw”

Somebody know a way to read a address from the MCU with openocd?
Or does somebody know a why this command is not available with my openocd
