Other Parts Discussed in Thread: USB-2-MDIO
Dear hi-tech fellows,
We are using the DP83867ERGZ-R-EVM as an Instrument under testing (IUT) for 1000M ethernet conformance testing.
BUT ONLY get signal from A channel, NO signals from B,C,D channels. (no matter in mode 1, 2, 3, 4)
Referencing "How to Configure DP838XX for Ethernet Compliance testing",
with USB-2-MDIO (a TI tool),we put REGISTER 0025 = 0x0480 ,then read, it shows 0000!
read REGISTER 0025 = 0x0000
We are not sure if there is something wrong with this REGISTER.
Other REGISTER such as REGISTER 0009= 0x3B00 is OK!
We are looking forward to your reply!
Sincerely , Mu
