Hi Muthukumar,

My understanding of the issue is that SGMII link is not achieved, is it correct?

Is MDI link able to be achieved? Are you able to read/write registers? If so, please share a register dump from 0x0-0x1E.

Thanks,

David

Hi Muthukumar,

Thanks for sharing the register dump. Can you please also read register 0x45D, 0x608, and 0x60A, 0x60D, and share the value both in good case and bad case.

Please also share the schematic for review.

Thanks,

David

Hello David Creger,

Please find the 0x45D, 0x608, and 0x60A, 0x60D register value of the good case

/ # phytool read eth0/0/0
0x2100
/ # phytool read eth0/0/0x45D
0000
/ # phytool read eth0/0/0x608
0000
/ # phytool read eth0/0/0x60A
0x0100
/ #
/ # phytool read eth0/0/0x60D
0x401f
/ #

bad case

/ # phytool read eth0/0/0x45D
0000
/ #
/ # phytool read eth0/0/0x608
0x0001
/ #
/ # phytool read eth0/0/0x60A
0x0100
/ #
/ # phytool read eth0/0/0x60D
0x401f
/ #

As per our analysis, In Bad case - sgmii_autoneg_en(0x608) got disabled.

Any configuration / driver change needs to update for this?

Kindly check and update.

Hi Muthukumar,

I am not sure the register reads are completed successfully. Note that the requested registers are extended registers, hence the extended register access procedure is required. Can you please read the same registers as above using the following sequence for each one?

Thanks,

David
