DP83867IR: PHY Identifier Register value

Shunsuke Nagata

Part Number: DP83867IR

Hi,

A DP83867IRPARP doesn't estamblish connection. As I checked PHYIDR1 and PHYIDR2 register of the device.
- PHY ID Register#1(PHYIDR1) = 0xE29E (default 0x2000)
- PHY ID Register#2(PHYIDR2) = 0xE29E (default 0xA231)

What is the 0xE29E meaning? is it specific code?

Regards,
Nagata.

Hi Nagata,

Looks like the communication to the DP83867 is not correct. The wrong values don't mean anything. They should be 0x2000 and 0xA231.

Please confirm you have PU on the MDIO line.
