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:

STM32L476G-EVAL and ST-LINK/V2 Connection Problem

Hello,

I can’t see anything on your pdf screenshot (too small) but anyway, check the board configuration script cfg produced, it should have:

  1. This is an L476_test board with a single STM32L476ZGTx chip.
  2. Generated by System Workbench for STM32


source find interface/stlink-v2.cfg

set WORKAREASIZE 0x18000
transport select “hla_swd”


source find target/stm32l4.cfg

  1. use hardware reset, connect under reset

reset_config srst_only srst_nogate


Then, maybe the jumpers on the eval board are at the wrong place.
Check that pwr_ext jumper is on.
That the jumper is on PSU for power supply and that the board has the external 5V supplied connected.
Check that no debug session are still running or openocd.exe task running.
And quit the stlink utility (or at least disconnect the session).

If this is still not working, what you can try also is to right click on the project name and do a Target->Erase chip before debug.


And why don’t you use the STLink V2-1 on the eval board to debug ?

Rgds,
Laurent
