 ====ewp.py: Create Makefile from IAR project==== ====ewp.py: Create Makefile from IAR project====
 +
 +ewp.py converts as best it can IAR project files into GNU Makefiles.
 +
 +===Install===
 +
 +<code>
 +hg clone https://hg.kewl.org/pub/ewp.py
 +cd ewp.py
 +sudo make install
 +</code>
 +
 +===STM32CubeH7 Demo===
 +
 +==Fetch Source==
 +
 +<code>
 +git clone --recursive https://github.com/STMicroelectronics/STM32CubeH7
 +</code>
 +
 +==Enter Demo==
 +
 +<code>
 +cd STM32CubeH7/Projects/STM32H745I-DISCO/Applications/FreeRTOS/FreeRTOS_AMP_RTOS_BareMetal/
 +</code>
 +
 +==List Targets==
 +
 +<code>
 +ewp.py . EWARM/Project.ewp
 +STM32H745I_Discovery_CM4
 +STM32H745I_Discovery_CM7
 +</code>
 +
 +==Create Makefiles==
 +
 +<code>
 +ewp.py -p1 . EWARM/Project.ewp STM32H745I_Discovery_CM4 > Makefile.cm4
 +ewp.py -p1 . EWARM/Project.ewp STM32H745I_Discovery_CM7 > Makefile.cm7
 +</code>
 +
 +==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.

 +</code>
 +
 +==Program==
 +
 +Program `Project.hex' with STM32CubeProgrammer (attempt using OpenOCD failed and needs investigation).
 +
 +==Notes==
 +
 +The demo FreeRTOS_AMP_Dual_RTOS initially runs ok and then stalls. This is due
 +to newlib memcpy causing an MPU unaligned memory hard fault.
 +
 +The FreeRTOS_AMP_RTOS_BareMetal demo works fine.
