@fzlee: nRF51 is still supported in FreeRTOS version in SDK 13/14, you can copy the following file into SDK 12.3 directory:

nRF5_SDK_14.0.0_3bcc1f7\external\freertos\portable\CMSIS\nrf51\port_cmsis_systick.c

This should add the latest fixes, as well as some small power optimization.

@dave_couling: We did not implement applicationIdleHook. If you are using tickless idle mode, you do not need to call application idle hook. If not using this mode, then they need to implement it yourself.

Hi Jorgen, For nRF51, the SDK after V12.3 is not supported. How to deal with it if I need to use freeRTOS on nrf51822

Thanks Jorgen, I updated to the SDK13 freertos code and everything works. Just as a curiousity, is the freertos example power optimized? Do I need to manually add Task Suspending and the ApplicationIdleHook( void ) for event resuming to optimize?

There are som issues with FreeRTOS in SDK versions below 13. Could you try upgrading to FreeRTOS files found in SDK 13 or 14?

do you mean what you wrote? "tasks are suspending properly" .. it sounds more like tasks are NOT suspending properly else why are you assking xTaskSuspend.
