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:

Depending on how you declare your variable in the C file, it may be placed in RAM or Flash. You could check in the output.map file that is created in the Debug folder.

To place the image in flash, you should declare it as const; then it should be placed in the .rodata section that is loaded in flash instead of SRAM; there you should have ample space to save quite big images.
