Hello Guys,
            I have one clarification related to PXA255 code in U-boot.
If in board/pxa255_idp/config.mk        TEXT_BASE = 0xa3080000 (this is RAM address in my board)

                        then because of -Ttext option (in u-boot/config.mk file), in U-boot.map file .text section starts from 0xa3080000 address.
                        So all the symbols like _start, _armboot_start get addresses with respect to 0xa3080000 address only.
                        I am using JFLASH to download the code in FLASH and running the code from FLASH. I am disabling that part of code which relocates the binary from FLASH to RAM.
                        What I don't understand is when in MAP file all the symbols have addresses of RAM then after downloading in FLASH, how code is executing?

Regards
Amit Kumar
