Keil mdk arm 5.23 download3/15/2024 ![]() I would like to get the FreeRTOS sources building with clang but I will have to look into that more later there were problems with compiler intrinsics and other port-specific things. I will be testing more so I’ll post updates if I come across anything strange. Right now I’m just happy it works so far. I have not tried attribute ((naked)) or looked at the generated assembly to see if it can be slimmed down. Then using the GCC syntax for assembly, for example, in ulPortRaiseBASEPRI: _asm( "mrs %, basepri msr basepri, % dsb isb" : "=r" (ulReturn) : "r" (ulNewBASEPRI) ) #define portFORCE_INLINE _attribute_((always_inline)) So far the only thing tricky I did was to make changes in portmacro.h. I have not been able to test everything yet but the basic tasks seem to be running with their expected timing, including interrupt handling with yielding from ISRs. That required setting “Enum Containers always int” and adding the compiler flag “–wchar32” in order to make a library that would link with the armclag-built code. File Downloads Download example projects and various utilities which enable you to extend the capabilities of your Keil development tools. I did have trouble building the FreeRTOS source itself, so I built that as a library with the old compiler. Download current and previous versions of the Keil development tools. I have good news – my whole project is up and running using armclang! Maybe not, as that won’t help with functions that are really macros. One possibility that occurred to me: could I build FreeRTOS as a static library, with the old compiler, and drop it into a project built with ARMCLANG? Is anyone else using this new compiler? Anyone else attempting a port? FreeRTOS is working great for me with the older ARMCC compiler. My target is a SAM4E16E (Cortex-M4) chip. I’m willing to try, but if it is going to be extremely hairy I’ll probably have to give up and use the old compiler. I’m not sure I’m up to the task of porting FreeRTOS myself. However, it supports a different syntax for inline assembly, and Keil’s docs don’t describe it well. I would love to use this compiler for my project as it has support for a much more modern version of C++, a lot better static analysis, more warnings, compiles faster, does the dishes and mops the floor, etc. Network Component 7.2.
