 Device ID : 0xcc
 Manufacture ID : 0x2c
 Page Size : 2048 Bytes
 Spare Size : 64 Bytes
 Pages_Per_Block : 64
 Number_of_Blocks : 4096

    Thanks, HappyNewYear, I think the address cycle and command table are the same with the one come with the EVM board, I am already test it on the EVM board, it works good so far, what I concerned is on the software side, like NAND partitions in Linux kernel, cause the size is doubled, Do I need modify some place there?
