DM355 boot problem,nothing is shown in the hyper terminal

Hi,

I build a dm355 board depending on DM355_ipnc.RAM is K4T1G164QD-ZCD5.NAND FLASH is K9F5608U0D,and it is listed in the table of supported Device IDs .

First,i have loaded ublDM355-nand-216.bin and u-boot.bin successfully by CCS3.3.Also,i set BTSEL[0:1]=00 and AECFG[3..0] = [ 1,1,0,1].

Then,I set up hyper terminal, connected and powered up the board,but nothing is shown in the terminal window.

I have verified that the serial port to hyperterm link works by running test program.

 

Any ideas?

 

Thank you very much.
