It seems that there is problem with your dpl file, please modify LSDK 21.08 original DPL file dpl-eth.19.dts as the following.

/* ------------ DPNIs --------------*/
obj_set@dpni {
type = "dpni";
ids = <0x0 0x1>;
};

Modify to:

obj_set@dpni {
type = "dpni";
ids = <0x0 0x1 0x2 0x3>;
};

Then adding the following section in "Connections" section.

connection@3 {
endpoint1 = "dpni@2";
endpoint2 = "dpmac@3";
};

connection@4 {
endpoint1 = "dpni@3";
endpoint2 = "dpmac@4";
};

thanks for Quick Reply and help .

After installing the dtb file getting the same error, Attached boot logs.

As per LSDK guide I will use the below command and try to load dpl file.

dtc -I dts -O dtb dpl-eth.19.dts -o dpl-eth.19.dtb

followed the below steps .

Hello,
We are facing a similar issue but we are able to detect dpmac3 and dpmac4 but when we try to test the link the link shows down. We are not able to bring 10G link up.
