STM32MP1 support available in SW4STM32

   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 download a short video showcasing this on the ac6-tools website (registration required).

CubeMX F4 projec with freertos will not build cos of asm instruction

Hi ST world,

I have the current issue when compiling freertos port.c file given in STM32F4 cube which seems the same than the previous one:

Compiler command:
arm-none-eabi-gcc -mcpu=cortex-m4 -mthumb -mfloat-abi=soft .... Lot of includes .... “../src/Middlewares/Third_Party/FreeRTOS/Source/portable/GCC/ARM_CM4F/port.c”

Output:
Error: selected processor does not support Thumb mode `vstmdbeq r0!,{s16-s31}’
Error: instruction not allowed in IT block — `stmdb r0!,{r4-r11,r14}’


I tried to remove -mthumb from the compiling command for this file only but I couldn’t find the way to do this in eclipse framework.

Any ideas ?
Thanks,
Sylvain

This build error is caused by an incorrect fpu specification in the build options, not by the -mthumb option (you must use -mthumb as the Cortex-M only supports THUMB 2 instructions).

Richard (http://www.freertos.org)
