Dear DP83849C experts,
I am working with a solution that uses a DP83849C phy. I have configured the phy, and have a BIST test in internal loopback mode, and the BIST test passes.
I have made an ethernet loopback plug, and have re-run the test, albeit with internal loopback mode disabled. It fails. Am I correct in thinking that if the BIST test passes with the internal loopback, it should also pass with the external loopback, and that if any failure in the test points to the section of the solution between the phy and the RJ45 pins ?
Kind regards,
Rocco
