...also do an "objump -h" on your elf file to see where everything is being located. Someone wants to locate a section in the wrong place or a section is way too large, but that is usually a symptom of locating a section in the wrong place or someone putting data in the wrong place.
Track down where that section location is defined and everybody that sticks stuff in that section looking for oddball locations (like 0x040000xx). Quite often someone puts in a hardcoded address in the code, causing a section to get really, really large.
I did a quick search and it looks like the common TEXT_BASE is 0x40000000 (not 0x04000000) so I may be wrong on that one.

This is the point, My flash is located at 0x02000000 and I erased this location before programming. But prog command for elf format file is trying to write to 0x04000000 and bin format writes to 0x02000000 ok.
The difference b/w bin & elf is that obviouly elf is much bigger. The elf image is about 1mb.

Did you erase 0x04000000 (and following) before loading?
Read those locations before and after programming and tell us what they have in them.

doing fine.
Try loading the ELF file instead - then GDB will automatically load all required information about source files.
