Hi

I have connected my mini2440 to a Com device using serial port.

when I try to boot, uboot always drops into the shell. If I remove the serial port connector, it boots happily.

Looks like the Com device is responding to the boot messages from uboot and uboot is dropping into the shell.

1. Can I prevent messages from uboot  into serial port

2. Can I continue to boot even if I drop into a shell (like automatically

typing "boot" in the shell) with a script like .bashrc equivalent

3. can I totally shutoff the serial port for uboot only

RTFM

see the main README, doc/README.silent, doc/README.modem, doc/README.autoboot in u-boot. There are lots of ways to handle this.
