T2080 with XFI 10G without PHY

[tapyang]

Dear, all:

I am developing the 10GBase-kr network of T2080, and our board designed that the serdes XFI is connected with XFP optical module directly and without use 10G PHY.

I changed the DTS as follows：

fm1mac9: ethernet@e0000 {
phy-connection-type = "xgmii";
fixed-link = <1 1 10000 0 0>;
};

However, It doesn't work. What should I do now?

Looking forward for your reply and thanks!~

Hi, Dear bpe:

The FSL_10GBASE_KR on SDK2.0 has already enabled. And, I checked the MDIO_XFI_PCS_SR1[PCS_RX_LNK_STAT] is not up.

When start the kernel, it says as followed:

what should I do now?

By defining the "fixed-link" property you effectively disable any PHY
initialization. This is the simplest approach which relies on
out-of-reset settings. You can check the link status in
MDIO_XFI_PCS_SR1[PCS_RX_LNK_STAT] and in the similar bit on the far
end. If the link does not go up automatically, consider enabling
FSL_10GBASE_KR option for SDK 2.0 or FSL_BACKPLANE for later kernels
and declaring the PHY in the Device Tree.

Have a great day,
Platon

This project is very hurry, and I have tried a lot of methods what I can try.

Please give me some notice for this, thank you!

Hi, Dear:

I think the 10G XFI without PHY need modify the "dtsi" file, and without burn PHY microcode.

Then what about the driver? I have already fixed the SPEED, then what should I do?

Looking forward for your reply!

Thx!
