LS1043A-RGW-B 10G optical

Hi, I have a LS1043A-RGW-B. We are trying to turn up the 10G optical interface (SFP+ optical transceiver).

1) I read the linux sdk documentation for 10G optical, i modified the hwconfig as in section

37.7.6 Environment variable hwconfig and optical 10G (page 886&887)

editenv hwconfig



2) Next, I modify the fsl-ls1043a-rdb.dts (and compile)

linux/fsl-ls1043a-rdb.dts at master · torvalds/linux · GitHub 

on the following section:-


ethernet@f0000 { /* 10GEC1 */
    phy-handle = <&aqr105_phy>;
    phy-connection-type = "xgmii";

to a fixed-link as below

ethernet@f0000 { /* 10GEC1 */
    fixed-link = <1 1 10000 0 0>;
    phy-connection-type = "xgmii";


When I connect to a windows based SFP+, I don't see SFP+ link up.

Next, on LS1043a-RGW-B uboot terminal, i do a ping to the windows SFP+, it cannot ping from TGEC1 to the windows. Could you please guide us on how to enable the SFP+ optical link?


many thanks in advance...
