  • Hello Liviu,

    I really cannot see why this should be a real mess. Up until now, CMSIS was released by ARM and there was no public repo at all (however most of the source code was available within the Pack itself).

    Now, the development work is done on CMSIS_5 and all upcoming releases will be done from this repo.
