PA_EMAC example , Packets are getting dropped at Packet accelerator.

Hi Manjunath jayram,

From our side, we were able to run the "PA_emacExample_K2KArmBiosExampleProject", example on K2H EVM and below are the output logs.

The following are the steps followed to run this example.

1. Set the K2H EVM in no-boot emulation mode.
2. Launch *.cxml of k2H EVM, connect the ARMcore 0.
3. Load the program, "PA_emacExample_K2KArmBiosExampleProject"
4. Run.
5. Will observe the ouput messages like below on the console.

Output logs:-
