SFP not working on LS1046A RDB

Hello,

Does anyone have made an SFP working in Linux with the LS1046A-RDB? Do we have to change something in the DTS?

In the DTS, the fm1-mac10, which is used for the SFP cage, is configured as a simple fixed link at 1Gbps. When I plug the SFP, nothing seems to go out of it. In front of this port, I have a Marvell MV88E6290 Evaluation card in 1 or 2.5 Gbps SFP, and I use a Finisar FCBG110SD1C01 (https://www.finisar.com/sites/default/files/downloads/fcbg110sd1cxx_10gbs_sfpwire_sfp-plus_acitve_op... ) for the connection.

All I could find on the SFP and Linux is this article of Russel King (Phylink & SFP support [LWN.net] ).

Thank you in advance for the help.

Marc

Hi,

Thank you for your confirmation. I had doubts that someone uses this card.

I didn't know that there was a hardware modification on the SFP link, no retimer. I needed only to change the rcw from RR_FFSSPPPH_1133_5559 to RR_FFSSPPPH_2233_5559.

Sorry for the inconvenience.

I will check this thread as answered.

By the way, I use a 4.12 kernel that is working on this platform.

Regards,

Marc

Hi, Marc,

I have the same situation as your.

Could you let me know where I can get the rcw file in RR_FFSSPPPH_2233_5559?

I just found the files in RR_FFSSPPPH_1133_5559 from SDK.

Hi, Marc,

Thanks for your reply.

I changed the serdes protocol in rcw_1800_qspiboot.rcw like following

SRDS_PRTCL_S1= 8755

 : 4403 (0x1133) --> 8755(0x2233)

Do I have to change any other value to set?

Hi,

I made this file. It is not in the SDK. You can modify the RR_FFSSPPPH_1133_5559 file and compile it.

Hello Marc,

I confirmed with Linux SDK testing team, SDK 1703 prebuilt image for LS1046ARDB supports 10G SFP+ fiber by default, Ethernet port fm1-mac10 should work normally with a 10G SFP optical transceiver module.

Would you please provide your u-boot and Linux booting up console log to let me do more investigation?


Have a great day,
TIC
