[U-Boot-Users] Jump location
Hi List, I have a confusion with Jump address. In case of MPC processor, I have reset vector at 0xffffffc which is mention is "board/<board_name>/u-boot.lds" script file. If we edit the binary file we used to get Jump instruction ..in my case its "4b ff f0 04" what exactly it means how it will jump to the location FFFFF000...I have seen this address in u-boot.lds script file. Can anyone put some commnet on this.
Thanks & Regards, Ricky

This is your second posting where you ask questions without giving any contect. Stop doing that. You MUST explain in detail which board and processor you ar eusing.
Without such context, the statement that for "MPC" processor the reset vector is 0xffffffc is plain wrong. It could be 0x0100 or 0xFFF00100.

No, nobody can help you with such unrelated questions.
Also I don't understand why you start with the binary image. The binary image is at teh very end of the chain. You start by reading the documentation, then reading and understanding the source code. Then you will probably port the code to your hardware. Only then binary files come into play.
