Dear All ,

I have been programming nand flashes via Jtag for a while. My M.P is TI's DM355, yesterday I builded the U-boot but when I turn on my pcb , I read some warning messages. I have added below the messages and I added the old U-Boot messages, they are different. I couldnt get the difference.

OLD ONE:

U-Boot 1.2.0 (Feb 2 2008 - 23:52:10)

NAND: NAND device: Manufacturer ID: 0x2c, Chip ID: 0xd3 (Micron NAND 1GiB 3,3V

8-bit)
