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.

"builtin-declaration-mismatch" warnings after update to V2.5.0


Hi Guy,

There are two solutions:

  1. Add -Wno-builtin-declaration-mismatch in the Other flags setting of the MCU GCC Compiler Miscellaneous tab
  2. Correct the eCos declarations to match the standard confused

The first solution is simple, but may mask real errors. The second is longer but safer; however you will have to correct eCos code after each eCos update (unless you are able to submit the correction to eCos...), something that would be simpler if you manage the eCos code under SVN or GIT as updates will retain your corrections.

Hope this helps,

Bernard (Ac6)
