I have a custom Zynq-7000 platform with GEM0 connected to a Marvell Link Street 88e6176 switch over MDIO running the Xilinx 2022. 3) RGMII is intended to be alternative to GMII, TBI and MII with the advantage of reduced number of pins with only 12 pins. dtsi (65. ><p></p> Problem is with 100/10 mode. > and i need to have the ability to configure both swithces via MDIO bus. 6. I used pinmux spreadsheet as below: image 757×229 11. Almost a the end of the log file you will find the messages below . Hello nv team： We need to use the XFI and RGMII interface on our custom carrier boad。But the RGMII not work. lee1 Jetson AGX Orin RGMII to use - #6 by WayneWWW I’m trying to setup RGMII for my 1Gb Ethernet on custom board. This is possible in RMII, SGMII, and RGMII. RTL8211F-CG uses RGMII interface. If I want to use 100Mbps,I should change speed = <100>. 2 KB) WayneWWW April 28, 2023, 9:03am 24. Hi all, I use the QSGMII core (in MAC mode) on Artix 7 with a custom pseudo GMII <-> RGMII Core which connects to a PHY. I know the zynq-7000 ps has RGMII drivers and MDIO drivers, That said, just about every RGMII board will use the feature in the PHY to adjust the phase of the clock to avoid the long PCB trace. 1 Experiment Objective Understand what Ethernet is and how it works Familiar with the relationship between different interface types (MII, GMII, RGMII) and their advantages and disadvantages (the development board uses RGMII) Combine the development board to complete the transmission and reception of data and verify Enclustra uses RGMII to make the connection between Gigabit Ethernet and the PHY chip in use, which is the Microchip KSZ9031RNX. If you have concern, then try You signed in with another tab or window. Currently this I have a customer board the MCU is TDA2PX , The RGMII connected a switch(sja1105p) directly, as shown as below: * Any redistribution and use of any object code compiled from the source code and any resulting derivative works, are licensed by TI for use only with TI Devices. 1 Experiment Objective Understand what Ethernet and how it works Familiar with the relationship between different interface types (MII, GMII, RGMII) and their advantages and disadvantages (here uses RGMII) Combine the development board to complete the transmission and reception of data and verify it 13. > You are correct, two MAC's cannot be connected together in MII mode. In order to achieve its goals RGMII uses both the clock edges (commonly called as DDR) and also uses multiplexed data and control signaling. 3V, but I would double check it if possible. Our custom board doesn’t use MDIO, MDC, reset GPIO and interrupt GPIO of RGMII. skew rate is controllable both at RGMII PHY and FPGA IC. IMX8MPXEC Rev. board-design, ethernet. F, Best Regards, Peter. dtsi”? And So, I tried to be up the eth0, It doesn’t work. Is there away to enable both to work simultaneously? Thanks. The data has to be 1/4 cycle offset from the clock IIRC, additionally most MACs and PHYs these days can compensate for that 1/4 cycle offset, but they have to be configured to do so, look carefully at your PHY datasheet to figure this stuff out. 0 using internal i/f and then on the PHY side have used the GMII to RGMII IP version is 2. c file. We were unable to get the DP83869 to work in Autonegotation mode. Find more, search Will RGMII work with a small constant delay in the range of 10~20ns on all signals? Related to this question. (i. 8 bits/9 signals. AM62x family of SoCs supports loading SPL and U-Boot over the network using DHCP/BOOTP protocol. I think the RGMII between the MAC and the switch is connected normally without errors in software, but the communication is not working. Reduced Gigabit Media Independent Interface (version 1. Our carrier board with L4T 35. It make sense because when the macro sgmii_fixed_link is enabled it changes the xAdapter. Like Liked Unlike Reply. The project is configured to take advantage of Vivado TCL scripting. 5, 3. ) Experiment 14 Ethernet Experiment 14. Let “CONFIG_MICREL_PHY=y”, Because I use ksz9031. The switch is connected to the Zync via RGMII with the GEM0 MII interface routed through the PL. The SGMII works fine from both u-boot and linux (SDK). Product Forums 23. RGMII, Reduced Gigabit Media-Independent Interface, is an interface standard between a FPGA and an Ethernet PHY supporting gigabit Ethernet. I found the device-tree code as below: Could I input this code to “tegra234-ethernet-3737-0000. 5 KB. 5. We understand that PHY should be power-up and out of reset before the ROMBoot execution. Dear NVidia Team In the topic JetPack 5. It kernel panic on r36. Automate any workflow Codespaces. In addition to the data signal reduction, the RGMII model time-multiplexes the TXEN signal with the TXER signal in TXCTL, and the RXDV with the RXER signal in RXCTL while eliminating the COL and CRS signals. 1 GMII2RGMII v3 in default configuration Zynq 7020 PS Ethernet #1 routed to GMII2RGMII v3 in PL to external Marvell PHY 88E1510 Standalone-Software based on XAPP1026 v51 (RAW_TCP only) BSP with default cofiguration of xapp1026 (incl lwip 141) this works: 1. my equipment: two LS1046ARDB boards with QorIQ SDK v2. 1 use rtl8211 can not work. v to use lattice ECP5 primitives for IODDR style and Clock input style?I have looked up the Lattice FPGA Libraries Reference Guide 3. Hello, I'll definitely look into that, thanks This is kinda a side project for me at work, and I'm heavily constrained by security on what I can and can't do so testing has been a bitch, but hopefully I can get somewhere with this. line SEL_RGMII should be set to 1 by MMC; pin CRS should be 1 for 1000Mbps RGMII-1000, is set by MMC via PHY_CFG_DDR !!BUT!! oddly is pulled low over 10k (R363) pin GPO2 should be 0 for DCE mode (parallel interface is to the MAC on FPGA), !!BUT!! is pulled high Let's say I am talking to a PHY chip via RGMII. Strictly speaking, this method is not compliant with the RGMII standard. 2 IP-core: GMII-to-RGMII 4. In this For all the zynq-7000 boards I've used, the lwip/tcp echo server example code just kind of magically works. 3 + 2 x RGMII/MII/RMI) and I am using only the 5 ports, I just wonder what to do with the remaining RGMII/MII/RMII unused interfaces (pins). The speed of the link is determined via the RGMII interface using counters. You signed out in another tab or window. The external ports are MAC ports supporting Media Independent Interface (MII) like MII, Gigabit Media Independent Interface (GMII), Reduced Media Independent Interface (RMII), Reduced Gigabit Media Independent Interface (RGMII), Serial Gigabit Media Independent Interface (SGMII) and Quad Serial Gigabit Media Independent Interface (QSGMII). The block diagram is shown in the figure. Use RTL8211 rgmii interface. Awesome, Thanks! FYI RE RM520 vs RM521: In my area, there are exactly 3x 5G channels available from my tower. (maybe it is the problem?) Could you please tell me how to solve these problems. Part Number: TMDS243EVM Other Parts Discussed in Thread: AM2434, , SYSCONFIG hi, I am trying to use the L1 FIFO of the MII_G_RT module on PRU1 on ICSSG0 of the AM2434 on the TMDS243EVM board. MX Forums. dtsi”? And case of AGX Xavier, It has device tree code for “ethernet@2490000” in “tegra194-power-tree-p2888-0001-p2822-1000. A clock skew can be integrated into the PHY for both RX_CLK and TX_CLK. A total For RGMII, the clock flows along with the data signals in each of the two separate groups, so matching will tend to make everything work. Plan and track work Code Review. I am having trouble RGMII was born the same way the original Ethernet was. 4. The following is the relevant information, how to locate the problem point, thank you! RX dropped continues to increase. 3, 5V Parallel SGMII 10/100/1000 Mbit/s 1 Lane 4 625 MHz Not well defined Serial (SerDes req. TEMAC generated with internal i/f works with a gmii2rgmii IP as the PHY interface. For 1Gbps the design is working fine. ) Speed Data Width Pin Count Clock Frequency Voltage level Interface type Speed Data Width Pin Count Clock Frequency Parameters Cost Interface type Standard xMII variants for When I check the RGMII line that receives a packet from the Ethernet SWITCH and sends it to AGX ORIN with an oscilloscope, the RGMII signal is output as (RGMII_RXC, RGMII_RD[0:3], RGMII_RX_CTL), but when I check ifconfig in the terminal, the RX packet does not increase as shown below. 0-1703 firmware. "Work" shall mean the work of authorship, whether in Source GEM0 -> is ETH0 (PS-EMIO-SGMII design) - Do not work but says link up at 100 FULL (it is attached to 1Gbits switch) GEM1 -> is ETH1 (PS-RGMII) - Work with the 1Gbits switch. sh -k A_kernel-dtb jetson-agx-orin-devkit mmcblk0p1 An update: we confirmed that the remote device RGMII interface that will connect to Zynq is actually LVCMOS18 compliant. Many of Quectel's modems support directly connecting to a PCIe Ethernet chipset. → Linux_for_ Experiment 14 Ethernet Experiment 14. 5. But it work fine on r35. 16: 591: December 19, 2023 ORIN uses RGMII to connect phy 88E1512, the network link is unavailable.
