ASPEED Ethernet PHY Evaluation Module
Description
The ASPEED Ethernet PHY EVM is a daughter card
intended to connect to ASPEED's AST2600 EVB
to show how the DP83867 and DP83869 Ethernet
PHYs can be used in a Board Management Controller
(BMC) system. The EVM contains four PHYs each
capable of 10/100/1000Mbps data rate.

    1 Evaluation Module Overview 1.1 Introduction The ASPEED Ethernet PHY EVM helps the user evaluate the features of Texas Instruments’ DP83867 and DP83869 in a Board Management Controller (BMC) context. This User’s Guide details how to properly operate and configure the EVM. The guide also includes hardware and software setup instructions for the ASPEED AST2600 EVB which the EVM is intended to connect to.
  • Page 3 First, open the following file: [BUILD_DIR]/openbmc/build/evb-ast2600/tmp/work/evb_ast2600-openbmc-linux- gnueabi/u-boot-aspeed-sdk/v2019.04+git/git/drivers/phy/Kconfig c. Then, edit the Kconfig file by adding the lines circled below. d. Second, add the DP83867 and DP83869 driver files to the proper directory. Open this TI-maintained repository and copy the DP83867.c and DP83869.c files.

  • Page 5 To change the IPv4 address of a specific PHY, run the following command in Tera Term: 1. ifconfig eth0 [IPv4_ADDRESS] 2. Note: the above command affects eth0 (the name assigned to the DP83867 PHY with VDDIO = 1.8 V). To configure other PHYs, use the names eth1, eth2, eth3. The block diagram in...

  • Page 8: Status Leds

    LEDs are active when there is any receive or transmit activity. The link status and link activity LEDs for the DP83867 with VDDIO = 1.8V is shown below (the silkscreen designators are D302 and D303).
  • Page 9 EVM using the J701 jumper header as described here. Once the board is powered on this rail, the user can connect jumper wires from a microcontroller like Texas Instruments's LaunchPad here. Connect the LaunchPad's MDC/MDIO jumpers to the EVM's MDC/MDIO jumpers of the desired PHY. Please reference the silkscreen below for jumper selection.
  • Page 10: Manual Reset

    This is achieved by driving the active-low pins of each PHY to LOW. The reset circuitry also has an automatic reset that is triggered when VCC (OVDD_3V3) falls below 2.93V. Figure 3-6.
