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.

Unable to change compiler version

Posted by Lucian Pop on 2020-01-06 14:59

Dear STM32 community,

I have installed Eclipse System Workbench for STM32 which defaultly camed with GCC 5.2.1 compiler revision.
It is mandatory for me to change the compiler version from 5.2.1 20151202 (release) ARM/embedded-5-branch revision 231848 to 4.5.3 in order to have traceability among other tools that are using same version.

I have tried downloading the compiler manually and changing “Project >> Properties >> C/C++ Build >> Settings >> MCU Settings >> Path” with 4.5.3 new compiler path.
Changing “${openstm32_compiler_path}” to “C:\arm-none-eabi-gcc-4.5.3\bin”.

I have attached the print screens taken before and after compiler change.

Looking forward for your reply!

I have an update!

While updating the compiler I was getting next error: “arm-none-eabi-gcc: nosys.specs: No such file or directory”.
I see that the problem was that I was using default 4.5.3 GCC compiler and not the ToolChain one for STM32.
The source code for this special compilers can be found ((https://launchpad.net/gcc-arm-embedded/+download|here)).

With this compilers and updating only the first parameter of the variable PATH, I was able to build with success my project. cool

Problem facing now is that GCC 4.5.3 compiler (which includes nosys.specs) is not supported by this website !

Can someone help me please ?! rolleyes
