  -d ==> use image data from 'datafile'

You should create a binary file from you ELF file with objcopy:

$ arm-rtems4.9-objcopy   -R -S -O binary hello.exe hello.bin

then:

$ mkimage -A arm -O rtems -T kernel -C none -a 0x30000100 -e 0x30000100 
-n "RTEMS Application" -d hello.bin hello.img

Gzip is not necessary => -C none (no compression)

I would love to change the world, but they won't give me the source code
