ewp.py: Create Makefile from IAR project
ewp.py converts as best it can IAR project files into GNU Makefiles.
Install
hg clone https://hg.kewl.org/pub/ewp.py cd ewp.py sudo make install
STM32CubeH7 Demo
Fetch Source
git clone --recursive https://github.com/STMicroelectronics/STM32CubeH7
Enter Demo
cd STM32CubeH7/Projects/STM32H745I-DISCO/Applications/FreeRTOS/FreeRTOS_AMP_RTOS_BareMetal/
List Targets
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.

Build
make -f Makefile.cm4 make -f Makefile.cm7
Combine HEX

Program
Program `Project.hex' with STM32CubeProgrammer (attempt using OpenOCD failed and need investigation).
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.
A work-in-progress port using this script can be found here.
