the sequence of boot in NIos II based HAL

I should copy everything -- but all of my applications run completely in RAM (I do not locate

rodata in flash for example) -- so I'm not sure how it behaves if you locate rodata in

non-volatile memory.

Regardless, as I recall, the "data" that the boot loader operates on is formatted as

a sequence of records (length, destination address, data). The loader just fetches

the length, and destination, then transfers the following bytes. When the length

is zero, the copy process is complete.

If you need more details, you should probably "use the force" ;-) and review the

source code -- You might also want to get some details on how elf2flash works,

since this is where the bootloader is married to your application code.
