Introduction[edit | edit source]

Petalinux 2024.2 allows to support dual Gigabit Ethernet configuration on BoraEVB and BoraXEVB. This application note describes how to implement such configuration, providing a reference design for Vivado 2024.2 and Petalinux configuration instructions.

Block diagram[edit | edit source]

Simplified block diagram of dual Ethernet configuration is shown in the following picture.

First Ethernet port refers to J8 connector of BoraEVB and BoraXEVB carrier board and is based on Zynq's Gigabit Ethernet Controller 0 (Gem0). This controller is mapped at physical address 0xE000B000.

Second Ethernet port refers to J9 connector of BoraEVB and BoraXEVB carrier board and is based on Zynq's Gigabit Ethernet Controller 1 (Gem1). This controller is mapped at physical address 0xE000C000.

The fundamental difference between the two interfaces is the PHY interfacing. In case of Gem0, PHY is mounted on Bora and BoraX SoM and it is interfaced directly to Processor Subsystem (PS) via MIO pads. In case of Gem1 instead, PHY is populated on BoraEVB and BoraXEVB (U9) and it is interfaced to Programmable Logic (PL). Thus it is necessary to enable EMIO routing and to instantiate a GMII to RGMII bridge in PL as per PHY's interface requirement. About MII bus (MDIO, MDC), two different busses are used:

Bora PHY is connected to the signals ETH_MDC and ETH_MDIO (available on BoraEVB at JP18.7 and JP18.9 respectively)
- this MII bus is associated to gem0
BoraEVB PHY is connected to PL's IO_L9N_T1_DQS_34 (ETH1_MDC) and IO_L9P_T1_DQS_34 (ETH1_MDIO); these signals are available on BoraEVB at JP18.8 and JP18.10 respectively
- this MII bus is associated to gem1
- it is worth to remember that a virtual PHY (whose address is 8) is connected to this bus as well; this PHY is implemented in the GMII/RGMII bridge and it is used to configure the bridge at runtime, depending on operating parameters such as the Ethernet physical link speed.

Vivado design[edit | edit source]

The following picture shows the block diagram of the Vivado project:

Bora + BoraEVB[edit | edit source]

On BoraEVB PHY1 is interfaced to Programmable Logic (PL) pads that belong to bank #34.

WARNING: due to a restraint introduced, from Vivado version 2017.1 onwards, the signal ETH1_TXCK can be routed only to a pad that is MRCC or SRCC input. As result from BELK 4.0.0 an hardware rework is needed on the BoraEVB board:

Remove R183
Remove R232
Connect R183.2 with R232.1

This rework prevents the use of the PL SDRAM onboard of the BoraEVB (by default this ram is not mounted).

Here is the pinout assignment for the PHY1 on BoraEVB:

PHY1 Signal	BORA SOM Signal
ETH1_TXD0	IO_L24P_T3_34
ETH1_TXD1	IO_L24N_T3_34
ETH1_TXD2	IO_L23P_T3_34
ETH1_TXD3	IO_L23N_T3_34
ETH1_TXCK	IO_L20P_T3_34
ETH1_TXCTL	IO_L20N_T3_34
ETH1_RXD0	IO_L5N_T0_34
ETH1_RXD1	IO_L5P_T0_34
ETH1_RXD2	IO_L7N_T1_34
ETH1_RXD3	IO_L7P_T1_34
ETH1_RXCK	IO_L4N_T0_34 IO_L13P_T1_MRCC_34
ETH1_RXCTL	IO_L4P_T0_34
ETH1_MDC	IO_L9N_T1_DQS_34
ETH1_MDIO	IO_L9P_T1_DQS_34

Since bank #34 is powered at 3.3V (High Range I/O mode), RGMII duty cycle distortion specification is not matched. In case of carrier board designed for production environments, it is recommended to use a lower voltage levels and thus a different PL bank. For more details please see section I/O Standard and Placement of PG160 GMII to RGMII LogiCORE IP Product Guide and this page.

The Vivado project can also be build with the procedure explained here.

Borax + BoraXEVB[edit | edit source]

On BoraXEVB PHY1 is interfaced to Programmable Logic (PL) pads that belong to bank #13.

WARNING: due to a restraint introduced, from Vivado version 2017.1 onwards, the signal ETH1_TXCK can be routed only to a pad that is MRCC or SRCC input. As result from BXELK 2.0.0 an hardware rework is needed on the BoraXEVB board:

Remove RP84
Remove R232
Connect RP84.2 with R232.1

This rework prevents the use of the LVDS connector on BoraXEVB (J26).

Here is the pinout assignment for the PHY1 on BoraXEVB:

PHY1 Signal	BORAX SOM Signal
ETH1_TXD0	IO_L19P_T3_13
ETH1_TXD1	IO_L19N_T3_VREF_13
ETH1_TXD2	IO_L20P_T3_13
ETH1_TXD3	IO_L20N_T3_13
ETH1_TXCK	IO_L16P_T2_13
ETH1_TXCTL	IO_L16N_T2_13
ETH1_RXD0	IO_L17P_T2_13
ETH1_RXD1	IO_L17N_T2_13
ETH1_RXD2	IO_L18P_T2_13
ETH1_RXD3	IO_L18N_T2_13
ETH1_RXCK	IO_L15P_T2_DQS_13 IO_L12P_T1_MRCC_13
ETH1_RXCTL	IO_L15N_T2_DQS_13
ETH1_MDC	IO_L21N_T3_DQS_13
ETH1_MDIO	IO_L21P_T3_DQS_13

I/O voltage of bank 13 must be set to 2.5V by configuring JP25 as shown in the following table.

Pins	Setting
1-2	closed
3-4	open
5-6	closed
7-8	open
9-10	open
11-12	open

The Vivado project can also be build with the procedure explained here.

Enabling dual Ethernet configuration in Petalinux[edit | edit source]

To use dual Ethernet user needs to get the pre-built binaries:

Alternatively user can built image with dual Ethernet configuration on Petalinux by following this guide and build artifact for config_bora_ETH1 or config_borax_ETH1 configuration files. In this case user need to update project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi file as shown below.

diff --git a/project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi b/project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi

(END)

In case of manual build with Petalinux, when user load xsa file, Petalinux make a series of device-tree in components/plnx_workspace/device-tree/device-tree, please check that this file are correct since this can have some error. This is an example

Performance tests[edit | edit source]

To test the performances of the second Ethernet interface iperf3 based tests have been executed.

After boot your board, user need to update network configuration file, for more info see dedicate page, below there is an example

On the linux host machine user need to apply a new ethernet connection with correct subnet, for example sudo ifconfig ethX:0 192.168.11.99 and perform iperf3 application in server mode:

bash# iperf3 -s

Here are the results of the test on the two Ethernet interfaces:
