Re-oppening since issue is only partially solved. When I created the issue, I could have been more specific about the places where it needed to be fixed. The comment was fixed in default_cfe_sb_internal_cfg.h, but it also needs to be fixed in example_platform_config.h It still says CFE_PLATFORM_SB_HIGHEST_VALID_MSGID lower limit is 1, up to CFE_SB_INVALID_MSG_ID - 1. and CFE_SB_INVALID_MSG_ID seems to be set to 0. https://github.com/nasa/cFE/blob/d0e9564b09ead61c60a8af235431a69b9aef85c0/cmake/sample_defs/example_platform_cfg.h#L1149C10-L1149C96
