Why does my Nios® II Simple Socket Server design example fail to auto-negotiate at 1G speed? - Why does my Nios® II Simple Socket Server design example fail to auto-negotiate at 1G speed? Description Due to the default timeout period in the Simple Socket Server template, there is a possibility that auto-negotiation at 1G speed may fail in Cyclone® V, Cyclone® 10, and Max® 10 devices. Resolution To work around this problem, the user is required to modify the BSP source code to increase auto-negotiation timeout delay and recompile to generate the new ELF file using the instructions below. Open the following file in the project directory: ../software/<project_name_bsp>/drivers/src/altera_avalon_tse.c Change the timeout delay from " usleep(1000)" to " usleep(5000)" as shown in the next portion of code: alt_32 alt_tse_phy_restart_an(alt_tse_phy_info *pphy, alt_u32 timeout_threshold) { …………………………………. while(alt_tse_phy_rd_mdio_reg(pphy, TSE_PHY_MDIO_STATUS, TSE_PHY_MDIO_STATUS_AN_COMPLETE, 1) == 0 ){ if(timeout > timeout_threshold) { tse_dprintf(4, "WARNING : PHY[%d.%d] - Auto-Negotiation FAILED\n", mac_group_index, mac_info_index); /* Restore previous MDIO address */ alt_tse_phy_wr_mdio_addr(pphy, mdioadd_prev); return TSE_PHY_AN_NOT_COMPLETE; } usleep(5000); //updated from usleep(1000) } Custom Fields values: ['novalue'] Troubleshooting 14010342674 False ['novalue'] ['FPGA Dev Tools Quartus® Prime Software Pro'] No plan to fix 18.1 ['Cyclone® Bare Die', 'MAX® CPLDs'] ['Nios® II Embedded Design Suite (EDS)'] ['novalue'] ['novalue']
