Ethernet on OSD3358-SM-RED

[tahmedx92]

Hi,
I am using OSD3358-SM-RED as reference design to build a custom board. I want to replace the Ethernet Transceiver IC (AR8035-AL1A ) with ( LAN8710 ) . Because ” AR8035-AL1A ” is not available.
Will it make any problem ? Will ” Custom Embedded Linux image for OSD3358-SM-RED platform” recognize IC ” LAN8710 “.
As I can see from schematic ” MII1_RXERR ” & ” MII1_CRS_DV ” signal are used in OSD3358-SM-RED for different purpose.

Please help me with issue.

Regards,
Tanvir

Tanvir,

You should be able to replace AR8035-AL1A with LAN8710. LAN8710 is used in Beaglebone Black. See https://github.com/beagleboard/beaglebone-black/blob/master/BBB_SCH.pdf for reference. Pin mapping between the AM335x used in Beaglebone Black and OSD335x family is shown here: https://octavosystems.com/app_notes/osd335x-family-pin-assignments/. Device tree for Beaglebone Black Ethernet can be accessed here: https://github.com/RobertCNelson/dtb-rebuilder/blob/4.14-ti/src/arm/am335x-bone-common.dtsi#L421.

Best,

Neeraj
