ewp.py converts as best it can IAR project files into GNU Makefiles.

hg clone https://hg.kewl.org/pub/ewp.py
cd ewp.py
sudo make install

git clone –recursive https://github.com/STMicroelectronics/STM32CubeH7

For each Makefile alter FIXME_CPU and FIXME_ABI for the CPU platform.

In these cases it is cortex-m4, cortex-m7 and hard.

Locate FIXME_LDS and ensure the correct linker script is selected and then remove the FIXME_LDS text.

Change paths to GCC from IAR in the FreeRTOS source and includes entries.

Apply this patch if you want the backlight to be disabled when running the demo.

Program with STM32CubeProgrammer

The demo FreeRTOS_AMP_Dual_RTOS initially runs ok and then stalls so it would appear to be buggy. FreeRTOS_AMP_RTOS_BareMetal works fine.
