Frequently Asked Questions - EVB-KSZ9131RNX Microchip
How do I power the EVB-KSZ9131RNX?
The board can be powered via USB (5V) or through a 3.3V/1.2V supply on the header. Connect USB for easiest setup.
Which host interfaces are supported?
The board supports RMII, RGMII, and MII interfaces. Select the mode via DIP switches SW1 and SW2.
What software is needed to test the PHY?
Microchip provides the LANCheck tool and Linux drivers. You can also use third-party Ethernet testers.
Is the board compatible with Arduino or Raspberry Pi?
Yes, you can connect it via GPIO headers with appropriate level shifting (3.3V logic). Refer to the user manual for pin mapping.
What is the maximum Ethernet speed?
The KSZ9131RNX supports 10/100/1000 Mbps (Gigabit Ethernet) over twisted pair.
How do I reset the board?
Press the reset button (SW3) or toggle the power supply. For hardware reset, pull the RST pin low for at least 1 ms.
Can I use this board for automotive applications?
Yes, the KSZ9131RNX is designed for automotive Ethernet (100BASE-T1 not native, but 1000BASE-T supported). Check the datasheet for temperature ratings.
What are the LED indicators?
Three LEDs show Link (green), Activity (yellow), and Speed (off=10M, green=100M, yellow=1G).
Where can I find the user manual?
The PDF manual is available on the Microchip website or via notice-facile.com. It includes schematics and layout files.
How do I update the PHY firmware?
The KSZ9131RNX uses configuration pins and registers; no user firmware update is needed. For advanced tuning, use the EEPROM interface.
