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 two short videos (registration required) highlighting:

System Workbench for STM32


Migration of code : libc problem.

I found this bug...
It seems the flag fpv4-sp-d16 was defined... and must not be defined in my project.

I am now on a new problem...

the generated file : “objects.list” contains some absolute path (windows form... M:/.........)
the compilation seems to be ok, but the code fall into WWDOG IRQ (without any reason)... some functions appears to be missed?

Manually : (in CMD.exe)

This works :
arm-none-eabi-gcc -T”“../QS/stm32f4xx_flash.ld”” -nostartfiles -L”../stm32f4xx” -Wl,-Map,Strategie.map -mcpu=cortex-m4 -mthumb -g3 -gdwarf-2 -o “my.elf” ./my_object1.o ./my_object2.o and all the objects ...

This does not work :
arm-none-eabi-gcc -g3 -gdwarf-2 -mcpu=cortex-m4 -mthumb -nostartfiles -L”../stm32f4xx” -T”../QS/stm32f4xx_flash.ld” -Wl,-Map=output.map -lm -o “my.elf” @”objects.list” -lstm32f4xx

objects.list contain the same list, but some objects are in this format :
“M:/R.../Debug/queue.o”
“M:/R.../Debug/state_machine_helper.o”
“M:/R.../Debug/zone_mutex.o”

My previous version of eclipse do not use this objects.list to build this linker command...
