ewp.py: Create Makefile from IAR project

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

STM32CubeH7 Demo

Fetch Source
Enter Demo

cd STM32CubeH7/Projects/STM32H745I-DISCO/Applications/FreeRTOS/FreeRTOS_AMP_RTOS_BareMetal/

List Projects

ewp.py . EWARM/Project.ewp STM32H745I_Discovery_CM4 STM32H745I_Discovery_CM7

Create Makefiles

ewp.py -p1 . EWARM/Project.ewp STM32H745I_Discovery_CM4 > Makefile.cm4 ewp.py -p1 . EWARM/Project.ewp STM32H745I_Discovery_CM7 > Makefile.cm7

Fix Makefiles

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.

Patch Source (optional)

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

Notes

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.
