Versioning of CMSIS Core missmatch

[JavierReyes945]

The latest release announced in the repository is the version 5.9.0

Some notes on the previous release 5.8.0 show that there were issues with the version shown in the cmsis_version.h.

At this very moment, the version shown in cmsis_version.h for the release 5.9.0 and newer commits show:

/**************************************************************************//**
 * @file     cmsis_version.h
 * @brief    CMSIS Core(M) Version definitions
 * @version  V5.0.5
 * @date     02. February 2022
 ******************************************************************************/

/*  CMSIS Version definitions */
#define __CM_CMSIS_VERSION_MAIN  ( 5U)                                      /*!< [31:16] CMSIS Core(M) main version */
#define __CM_CMSIS_VERSION_SUB   ( 6U)                                      /*!< [15:0]  CMSIS Core(M) sub version */
#define __CM_CMSIS_VERSION       ((__CM_CMSIS_VERSION_MAIN << 16U) | \
                                   __CM_CMSIS_VERSION_SUB           )       /*!< CMSIS Core(M) version number */
#endif

Which version is supposed to be the CMSIS Core version? Is this an issue with outdated info in cmsis_version.h, or does CMSIS have some other versioning system and what the header shows is not exactly the version of the whole release?

Hi @JavierReyes945,

I appreciate this is a bit confusing. The CMSIS Release version 5.9.0 relates to the bundle while the cmsis_version.h from CMSIS-Core relates to the component version, which is 5.6.0.

Cheers,
Jonatan

Thank you for the clarification. It would be adviceable to document this somewhere, perhaps the main README.md.

Good catch. Perhaps we enhance this for CMSIS 6 here: https://github.com/ARM-software/CMSIS_6.
Would you add a section that reflects your understanding?
