objcopy is copying sections .entry, .exceptions and .text ... and filling

the hole between .entry and .exceptions:

0081_8000 ... 0081_801F : .entry

0081_8020 ... 0100_001F : fill (about 8 MB)

0100_0020 ... 0100_0267: .exceptions

0100_0268 ... 0100_0357: .text

You need to locate your .entry code to SDRAM -- then things should

work ok.
