DP83848C: What power on/boot tests are required for DP83848C

Marshall Lee

Part Number: DP83848C

Tool/software:

I am working on some ancient fw code and I am finding that the power on/boot loopback code. And I am wondering how important(required?) is it to execute loopback test at every power on/boot cycle?

thanks for your input.

Hi Marshall,

You do not need to perform a loopback test at every power on. Loopback tests are primarily for validating the MII/MAC interface before the design goes into mass production.

If the loopback test works, you do not need to keep doing it.

Best,

Shane
