STM32MP1 support available in SW4STM32

   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 download a short video showcasing this on the ac6-tools website (registration required).

stm32L4-Discovery and cubemx ?


Monday i did get a stm32L4-discovery
into cubeMX just make a project and import to openstm
into the while
in openstm nothing happen ...no failure no flashing leds..

in IAR everything went smooth

Why ?



i think the problem is in line 6 but not sure what it means ....and last in the screendump you can see that the target halted ...dont now how to start ..

Can no one help ??

My other boards stm32F4 and Stm32F429 and Stm32F/ are working with cubeMX and open stm but the STM32L4 do not ...The code i generate in cubeMX for either ewarm or stm work on IAR but not on OPENSTM ...

Where to look after the problem ?


Run the ST-Link Utility and verify that the target communication mode is set to “Connect Under Reset”. My understanding is that if this option is not set for a L family device then the ST-Link can’t communicate with the target device.

hi ...i already did that......i was on the stm32l4 seminar and there they told me to do.....

other suggestions ?
