I have an application that is running on CMSIS RTOS V1 and i want to integrate a new application that is running on CMSIS RTOS V2 , Is there any way this can be done by using both the versions at the same time ?
yes, you can mix RTOS v1 and v2 in the same project. Follow the section "Level 2 Migration - Use API v2 and v1 alongside in RTX5" on arm-software.github.io/.../os2MigrationGuide.html
