Linux: DP83867IRRGZ

Other Parts Discussed in Thread: DP83867IR

Tool/software: Linux

Gents!

I am looking to implement a solution for:

- Built-in Self Test (BIST) circuit to accommodate in-circuit testing or diagnostics.

- Active Link Cable Diagnostic (ALCD) to provide a passive method to estimate the cable length during active link.

- Time Domain Reflectometry (TDR) to determine the quality of the cables, connectors, and terminations in addition to estimating the cable length.

on an embedded linux device where the DP83867IR is used. I am planning to use e.g. "phytool" for register read/write.

Instead of re-inventing the wheel; if perhaps someone out there have already done this and have bash shell script(s) (or C/C++) to share that would be highly appreciated.

Thanks.

    Hi,

    You can use register configuration provided in datasheet to implement BIST and TDR. We are not aware of readily available Linux implementation.

    Thanks.

    I made a simple test running Digital Loopback Mode as follows (the register write/read are all shown, together with some decoded info.).

    The following test run 7-8 loops doing the same:

    If I then run similar test, but then using Analog Loopback Mode I can rarely seem to get a "PRBS Lock" during the test.

    Am I missing something?
