https://community.nxp.com/t5/i-MX-Processors/Iperf-server-crash-on-FEC/m-p/1341544#M180237 <P>We have a custom Hardware where in i.MX6SoloX processor is being used. A microchip KSZ9477 ethernet switch IC is interfaced with processor using RGMII interface to FEC1 controller of i.MX6SoloX processor. The Linux kernel version 4.14.200 is being used. We have enabled CONFIG_1588_PTP.</P><P>The KSZ9477 ethernet switch driver is available at following location:</P><P><A href="https://github.com/Microchip-Ethernet/EVB-KSZ9477/tree/master/KSZ/linux-drivers/ksz9897/linux-4.14/drivers" target="_blank">https://github.com/Microchip-Ethernet/EVB-KSZ9477/tree/master/KSZ/linux-drivers/ksz9897/linux-4.14/drivers</A></P><P>We are connecting 2 such customer hardware and making them client and server.&nbsp;</P><P>To check the network performance, we are using iperf3. But we see a crash on iperf3 server. Please find attached logs.</P><P>We suspect that this crash is because of PTP is enabled in both FEC controller and KSZ9477 Switch driver.</P><P>Any suggestion is highly appreciated.</P> Thu, 16 Sep 2021 11:24:13 GMT parth_shah 2021-09-16T11:24:13Z https://community.nxp.com/t5/i-MX-Processors/Iperf-server-crash-on-FEC/m-p/1341544#M180237 <P>We have a custom Hardware where in i.MX6SoloX processor is being used.
