I am using U-boot loader 1.1.4 with ARM Integrator/CP. I ported my u-boot loaders and kernel in Flash and while running i didnt get any warning information for default environment. I could ensure that board has not been loaded with default settings. However while displaying __bdinfo__ i am getting bad instructions. I could see my settings are crashed. I could see the value of ARCH only has crashed.

I don't understand. What exactly is happening? Does "getting bad instructions" mean that U-Boot crashed with an illegal instruction exception?

What does "the value of ARCH only has crashed" mean? Do you want to tell us that the content of bi_arch_number is wrong? In which way is it wrong? What does "crashed" mean? Do yoiu have reasons to assume that there was a correct value stored in this variable, and it suddenly changed the content?

Is bdinfo using Hex value for Arch and Params?

Oops? Please look up the structure definition. These are plain binary data (unsigned long).

How to change the ARCH and params in Run Time?

You don't. The code is supposed to set up the values correctly.

While I am trying to copy my flash data into __0x7fc0__ entry always I

Please define what "my flash data" means, and how exactly you are trying to copy it, and why you think that 0x7fc0 would be a good address to copy to.

am getting bad magic number and when I came to display my entry using __md__ no data has been copied into memory in __0x7fc0__. Where will be the problem?

The main problem is with your way to report the problem - you don't provide any clear information (like logs of the actual error messages), and your description is a bit vague.
