FreeRTOS with configUSE_TICKLESS_IDLE activated causes a bad behaviour in the RX of UARTEhttps://devzone.nordicsemi.com/f/nordic-q-a/17516/freertos-with-configuse_tickless_idle-activated-causes-a-bad-behaviour-in-the-rx-of-uarteHi to everybody, I am working with nrf52 and SDK11. In my project I am using freertos and an UARTE with this configuration: 9600bps TX/RX (no CTS; no RTS) HW flow control disabled. No parity. DMA. DMA TX buffer of 16 bytes.en-USTelligent Community 13Thu, 10 Aug 2017 08:08:51 GMTRE: FreeRTOS with configUSE_TICKLESS_IDLE activated causes a bad behaviour in the RX of UARTEhttps://devzone.nordicsemi.com/thread/67348?ContentTypeID=1Thu, 10 Aug 2017 08:08:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c557bf9e-4b9e-484d-8760-7bdcc8d9434aSusheel Nuguru<p>sorry i forgot to update this thread and don&#39;t remember the conclusion. @dpa, do you remember the conclusion? or can you please give me the case number so that i can find it?</p><div style="clear:both;"></div>RE: FreeRTOS with configUSE_TICKLESS_IDLE activated causes a bad behaviour in the RX of UARTEhttps://devzone.nordicsemi.com/thread/67347?ContentTypeID=1Wed, 09 Aug 2017 23:40:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9463f910-23c2-49f7-a15d-1ff6668aaac0Mariano<p>Hi! any news about this post?</p><div style="clear:both;"></div>RE: FreeRTOS with configUSE_TICKLESS_IDLE activated causes a bad behaviour in the RX of UARTEhttps://devzone.nordicsemi.com/thread/67346?ContentTypeID=1Fri, 04 Nov 2016 12:57:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9f60a21d-2b50-4b4c-96ae-0cfa4f765adddpa<p>Ok!

This is much secure and we will be bound to NDA if you upload your code here. Please also attach your project, tell me steps to reproduce the error.</p><div style="clear:both;"></div>RE: FreeRTOS with configUSE_TICKLESS_IDLE activated causes a bad behaviour in the RX of UARTEhttps://devzone.nordicsemi.com/thread/67344?ContentTypeID=1Fri, 04 Nov 2016 12:23:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7c7b8303-6cb7-4348-a717-878125b1c117dpa<p>If configUSE_TICKLESS_IDLE is not set the UART receives ok!</p> <p>The project is for a propietary platform not for a DK.

The interrupt handlers called are not FreeRTOS related at all for UART. So any events triggering the UART interrupt must have correct bytes received in the hardware irrespective of any irregularities in FreeRTOS port. Probably there is some incompatibility with the SDK drivers and FreeRTOS interrupt handling!!?? Not sure. For me to be able to debug, i request you to upload your project so that i can see the problem and attempt to debug it.</p><div style="clear:both;"></div>
