Why is my Nios® II Simple Socket Server (RGMII) design example Ethernet link down when running on Intel FPGA Development Kits with MARVELL PHY?
Description Due to a problem in the Nios® II Software Build Tool, the default settings for the Nios® II Simple Socket Server (RMII) template are not targeted to MARVELL PHY. This resulted in wrong PHY...76Views0likes0CommentsWhy does the Arria® 10 Multi-Rate Ethernet PHY IP in USXGMII Auto-Negotiation mode fail in simulation?
Description The Arria® 10 Multi-Rate Ethernet PHY IP default value of usxgmii_link_timer at register address 0x412 is 0x7c000. This default reset value sets the link timer to 1.6ms, which is too l...68Views0likes0CommentsWhy is the timestamp accuracy error of the 1G/2.5G/5G/10G Multi-rate Ethernet PHY Stratix® 10 FPGA IP with MGBASE-T Ethernet design higher than the expected value?
Description Due to a problem in the Quartus® Prime Pro Edition Software Version 22.3, Stratix® 10 PTP designs using the 1G/2.5G/5G/10G Multirate Ethernet PHY FPGA IP MGBASE-T variant may o...69Views0likes0CommentsWhy does my Intel® Arria® 10, 10G Multi-Rate Ethernet PHY - Lineside IP fail timing between the MAC and PHY on the TX datapath?
Description When using the Intel® Arria® 10, 10G Multi-rate Ethernet PHY - Lineside IP core, you may see hold timing violations for the data transfer from alt_mge16_phy_xcvr_term module to&n...74Views0likes0CommentsWhy does the Ethernet link fail to come up during the U‑Boot stage after reboot on the Agilex® 5 FPGA 013B Dev Kit GSRD HPS?
...uring the initial power‑on boot, the problem does not occur because the operating system uses a generic Ethernet driver. The issue arises because the Micrel PHY driver is not enabled by default in t...30Views0likes0CommentsIs PHY Loopback supported using the Triple Speed Ethernet IP in Cyclone® V or Arria® V devices?
Description Serial Loopback is not supported in Arria® V or Cyclone® V devices with GX transceivers. The Triple Speed Ethernet (TSE) user guide states that "The serial loopback option is not s...64Views0likes0Comments
