Hi,

my first idea would be that the file format does not match the
expectations of your bootloader.

If I recall my hex code table right, then the bytes interpreted as the
first opcode:

00005000 7F454C46  WORD        $7F454C46

might be the string "~ELF" of the elf file header. so I assume that
"hello.exe" is an elf file, but your boot loader doesn't interpret it
right.

maybe you should feed it with a binary format? Or S-records? Have a
look into the BSP documentation (README etc), maybe you find some
hints there.

by the way: A proper email subject would help idetnify the postings
;-) No offense meant.

wkr,

Thomas.
