PQ2FADS-ZU u-boot serial issue

Hi,

I am having a problem while trying to communicate with u-boot using serial RS232.

I am using putty to communicate with Freescale PQ2FADS-ZU on which i successfully flashed u-boot.

When the board boots up and u-boot shows its intial configuration and then the command line prompts appear, however before i am able to type any u-boot commandline commands the letter 's' is automatically sent a number of times , and perhaps thats what hangs up u-boot and it refuses to take any further commands. I am attaching a picture. Require your help. Stuck on this for days.

 

Regards,

David
