Hi,
Today I just have gone through the code, for some reference and this is what
I understood.

the address you have to use is physical address only. because, it
bootloaders normally works in physical address only, not virtual address.

as you said, you are able to download atleast 300 packets, that is proved.
now, why it is failing after that, you have to find out!
one possible option is that, the kernel is overwriting the bootloader area.
check your boot.bib and config.bib. check your ROMOFFSET where it tries to
load the NK.BIN.

possibly this could be the problem.

> Which address I need to specify in boot.bib? Physical / Virtual?
physical.
> boot.bib I need to give Flash address OR SDRAM Address?
it depends on the type of build. if you are building for Flash it should be
flash or else RAM
> Is nk.bin configuration in config.bib should follow eboot configuration in
> boot.bib? for SDRAM Image?
certainly not. because, the configuration files in config.bib all should be
virtual and boot.bib is physical ! :-)

Best of Luck
