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:

stm32L4-Discovery and cubemx ?

Posted by skovholm on 2016-03-09 22:52

Hi

Monday i did get a stm32L4-discovery
into cubeMX just make a project and import to openstm
HAL_GPIO_WritePin(GPIOB, GPIO_PIN_2, GPIO_PIN_SET);
HAL_Delay(500);
HAL_GPIO_WritePin(GPIOB, GPIO_PIN_2, GPIO_PIN_RESET);
HAL_Delay(500);
into the while
in openstm nothing happen ...no failure no flashing leds..

in IAR everything went smooth

Why ?

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.
