How to generate a error free code with FreeRTOS for STM32G030 with STM32CubeMX for MDK-ARM

[kaushikbm]

I'm using the latest 6.7.0 version of STM32CubeMX for generating the code. I'm selecting just the serial wire and the a different timer for tick generation and nothing else. The code generation is completed without any errors.

But when I try to compile I get about a zillion errors regarding FreeRTOS. Did a lot of search and tried different solutions provided. Like this one here. But nothing worked so far. :weary_face:

Has anybody tried similar config ?

Thanks in advance for your help :smiling_face_with_smiling_eyes:

Here is the starting and ending lines of the build output. Had to snip off a bit as the post was getting too long. :grinning_face_with_sweat:

[Pavel A.]

It looks that the FreeRTOS is compiled with a wrong style of inline assembly, not intended for Keil V.6 compiler (Clang). It could work perhaps with Keil V.5 compiler (armcc).

Hey Pavel,

Thank you for the pointer. I tried changing to V5 compiler. Now I'm getting the following error :pensive_face:

It stops after generating 95 errors !
