When not using tickless idle, this works fine. When I turn tickless idle on however, the timer is not properly reset, even after using SDK 12.1. Is this still a bug in the Freertos port or am I doing something wrong here?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Freertos tick issue on nRF52.

&lt;p&gt;I have implemented the fixes you included in this post and our FreeRTOS implementation and we are still missing ticks which is causing our system to lose time.  Any ideas on how to correct this?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
