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:

Reinstalling STM32F745G-DISCO Demo


Hello ViveBob,

As I know STM32F746G-DISCO demonstration graphic content is stored within N25Q128A external flash memory.
I think that your problem is that openocd cannot program this external flash memory.

To do this you have to convert your elf file to hex, and program it using ST-Link Utility (at least v3.7.0) available in http://www.st.com/web/en/catalog/tools/PF258168Question

before you load the hex file you should select “N25Q128A_STM32F746G-DISCO” Nor Flash from Menu > External Loader > Add External Loader

Best Regards,
