nios2-elf-objcopy BUG??

Hi m_fox,

Because it is the correct format for intel-hex. The address is specified

as CS:IP (code segment register value:instruction pointer register value).

Together they form a 20-bit segmented address.

No, this would generate the linear address 000_01e8. The first two bytes "2000"

represent bits [19:4], the second two are bits [16:0] ... the two values are

added together in the proper bit positions. Basically, the correct values

are added like this:

20000 (CS)

001c8 (IP)

--------------

201c8 (20-bit linear)

No, it is not a bug.
