Sometimes, after a time operating normally, the ping reply time suddenly gets higher.

I saw already (debugging the system) that when ping response times gets higher, the RX Consume index is different from the RX Produce index, unlike the normal operation, where the 2 indexes (Produce and Consume) are always equal.&nbsp;I'm using CMSIS driver for the Ethernet peripheral.&nbsp;</P><P></P><P>Has anyone ever experienced this?

However, these examples don't use the CMSIS libraries.</P><P></P><P>If you would like more information do let me know.</P><P>Have a great day!</P><P>Sabina</P></BODY></HTML> Wed, 22 May 2019 16:42:07 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC1788-Ethernet/m-p/901532#M36199 Sabina_Bruce 2019-05-22T16:42:07Z
