Ah, I see.  I also do not know why that is not working.  You said that
readelf shows that the section is at the correct address.  You could use
objdump -s -j SECTIONNAME to check that the section has the right
contents.  If those all look correct, then you will need to look at your
loader to see what it is doing and why it is not working as expected.
