[U-Boot-Users] How to add new /board specific command to uboot ?

Hi Friends,

I tried to add a new command for my nmdk8810b6 board following README ./commands file.

Uboot just hangs at the initial stage even i doesn't boot , i don't see the uboot-1.1.4 text even.

I see some junk characters then it stops there.

I did following things

1, created a file for my command "cmd_dvt.c"

which has UBOOT_CMD( ) and parameters a function for my command

2,I included common.h command.h and dvt.h from where my command function reads the data.

3,I placed my cmd_dvt.c file in theTOPLEVEL /common directory.

4, I have included cmd_dvt.o in THE SAME Makefilewhere most common commands are compiled.

Did i miss something ? or i am placing it in a wrong directory ?

Do i need to place this command in the /include/configs/nmdk8810.h file ?

or anything else ?

I would appreciate your pointers on this
