Hi Sirs,

Sorry to bother you.

We need check how to Configure DP838xx for Ethernet Compliance Testing.

The document only show Giga/100 have test mode, but 10 didn't. only had loop back

We don't know how to start SI test on 10, could you help us to check?

Thanks!!

Hi,

App Note has given two commands.

10 Base Link Pulse:
Reg 0x001F = 0x8000 //reset PHY
Reg 0x0000 = 0x0100 //programs DUT to 10Base-T/Te Mode
Reg 0x0010 = 0x5008 //programs DUT to Forced MDI Mode
10 Base Standard:
Reg 0x001F = 0x8000 //reset PHY
Reg 0x0000 = 0x0100 //programs DUT to 10Base-T/Te Mode
Reg 0x0010 = 0x5008 //programs DUT to Forced MDI Mode
Reg 0x0016 = 0x0020 //programs DUT to Phy Loop-Back

First one can be used for Link Pulse Test.

Second one, Loopback is done to bypass the link-up check only. You can use internal PRBS generator to send the packet out and perform remaining test.

Geet

Hi Sirs,

Thanks for your reply

There have two command on App Note, one is Link Pulse and another is Loop back.

So, these are general test on base 10 compliance??

Thanks!!

For second, Loop Back is needed to enable Phy bypass the Link_up with link partner still transmit the packet out for Compliance test.
