Add SGMII Ethernet on LS1028A

pjw — Thu, 13 May 2021 02:04:12 GMT

Hi, I'm using LS1028A for development custom board.

Currently, one port of SGMII Ethernet and four ports of QSGMII Ethernet are available on ls1028 bsp.

The figure below is SGMII Ethernet what I found in LS1028A Reference Design Board Reference Manual.

In addition, SGMII confirmed that it was using QUALCOMM AR8033 48-PIN QFN and QSGMII using NXP F104S8A 138-PIN QFN.

What I want to do is change the existing QSGMII to SGMII.

There are currently four Ethernet ports available for QSGMII, which, if changed to SGMII, will use one.

In other words, the result is two SGMIIs.

I wonder if it's possible.

And if I can, can I get the data or guide related to this?

It would be good to have data related to hardware or data related to s/w.

I'd appreciate it if you could give me some information.

Thank you.
