RTX RTOS for Cortex-R and -A series

techguyz

Hi experts,

Is the Keil provided RTX RTOS seems to have only code for Cortex-M series.

Is it portable to Cortex-A and -R series as well ?

    Yes, a version of RTX that has been ported to the Cortex-A9 is available as part of the ARM DS-5 Development Studio.

    Note that there are significant differences between the Cortex-M and Cortex-A9 ports of RTX due to the significant differences in the two Architectures, for example, in the areas of timers, caches, execution modes, etc.  Sorry, I'm not aware of any port to the R-class family. 

    The latest version of ARM® DS-5 Development Studio is 5.18.1. You can download a free 30-day trial from http://ds.arm.com/downloads/.  After installing DS-5, look for CMSIS_RTOS_RTX.zip in the Examples directory.
