Why are you doing this? Keeping the Linux kernel image separated is much more flexible.
But when I give the address from where my kernel is starting (in the appended .bin file), I can just see the message
starting application at 0xa000ebc4.... (which is the address of the kernel )
You must be doing something seriously wrong here. To boot a Linux kernel you have to use the "bootm" command, which never prints such a message.
How can I check whether the bootloader and kernel are copied to the ram from the flash, as I'm not using the network features to download the image.
If you Linux kernel image is aligned to a flash sector then the "imls" command will find and verify it. If it is not aligned you should reconsider why you are doing this (differently than the rest of the world).
