Hi.
I have found the solutions.
1. Link down problem with VT864 chassis.
-> Let the TMDSEVM6670 RBL Etherboot with "force link" boot configuration.
and Turn off the auto nego of ethernet switch port in MCH.
2. little endian -> big endian
Follow the direction in "MCSDK_2_01_02_06/tools/writer/eeprom/docs/README.txt
