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 .

fsl-mc: Deploying data path layout ... WARNING: Firmware returned an error (GSR: 0x3f)

Can you please suggest how to solve.

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";
};
