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.

uses VFP register arguments

Posted by Dennis Yeung on 2015-02-14 12:39

Hi All,

When I compile the STM32f429 emwin libary, I got the error message of use VFP register arguments,
I search from internet that states it can be solved by mfloat = abi-hard inside c code,

Can anyone let me know how to set mfloat parameter inside the workbench?

Hi Dennis,

There is currently a limitation in the FPU support in the IDE; you should, in the library and application project, add “-mfpu=fpv4-sp-d16 -mfloat-abi=hard” in the Miscellaneous Settings of the C and C++ compilers.

In the next release, that should be available before the end of February, the proper FPU mode will be automatically selected whenever the targetted MCU has an FPU.

Hi Bernard,

Many Thanks for your support!

Now, I can use emwin in the System Workbench for STM32.
Your Suggestion help me save a lot of time.
