I think it's those initial dots that are causing the problem. Why have you put them there?

Its the part of command .

and if i did not followed . then it giving me as below.

test06:/home/balijepalli/pandaboard/toolchain# arm-2011.03-42-arm-none-eabi.bin -i console
arm-2011.03-42-arm-none-eabi.bin: Command not found

Right. This looks like the standard way of indicating that a command is in the current working directory by using the period as a shorthand. But because it's a shorthand for the name of the current directory, it needs to be integrated into the pathname just as that name would be. Remember, all components of a path must be separated by slashes, not spaces.

Your first command is chmod which is on the normal command path so you definitely don't need a period in front of that. What that command does, by the way, is to make the arm file executable so that you can subsequently use it as a command in its own right.

Then use the period as the first element in the path of the second command:

chmod 777 arm-2011.03-41-arm-none-linux-gnueabi.bin
./arm-2011.03-41-arm-none-linux-gnueabi.bin -i console

Don't put any spaces in the pathname. The period followed by a space was misinterpreted as a command in its own right and that's what caused the problem.
