Difference in addresses

Hi Team,

I am using NXP's T2080 RDB board, codewarrior v10.5 for uboot debugging.

currently i have few queries as follows:

1. the address in objdump of u-boot and the address in codewarrior disassembly are different.

Note: i have loaded the u-boot at 0xEBF40000 address on the alternate bank and giving a breakpoint at _start and it is hitting that breakpoint. but the addresses are different as shown in the image attached.

2. Are there any settings to be done to get the same address as present in the objdump or the load address of Flash.

That said,

Do you have the steps for performing the debugging. i have already followed the documents but it has not worked for me.

Thanks in advance,

Irfan

Please understand that U-Boot memory map (including the alternate Flash bank) does not exist during the processor power-up, when first fetch is a burst read of boot code from effective address 0x0_FFFF_FFC0 - refer to the QorIQ T2080 Reference Manual, 4.3.3 Boot Space Translation.
