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.
