First, you don't link your stuff at all, you're trying to feed a
relocatable object file into your MCU.  That doesn't work.

Second, your objcopy line misses the -j .data option, which is
repsonsible for copying over the initialization data for your
initialized variables -- exactly the problem you're seeing.

If you don't fully understand all implications, why are you rolling
your own set of commands, instead of resorting to a known-to-be-good
Makefile to produce your loadable hex file?
