Hi,
Thanks for the help. I've actually tried using the function you
suggest, but gotten the following error:
sparc-elf-gcc -O1 -W -Wall -DPROLBASE=0xffd00000 -DPROLDATA=0xffd0b000
-DPROLRODATA=0xffd08000 -D__ANSI__=1 -I../src -mcpu=hypersparc

sparc-elf-ld: proll.elf: section .rodata lma 0xffd08000 overlaps

make: *** [proll.elf] Error 1
However when I tried your code snippet it works fine. It seems that it
only works if I call that function from an infinite loop (big loop or
loops with a break statement don't compile either), which is driving me
nuts. Do you know why this is?
Also, some additional background info. I am actually using the
-nographic option. This project is for a grad class on computer
architecture. The prof. says he has a sparc processor implemented on an
fpga and wants to load linux on it, but it doesn't have a hard drive or
network connection, so that is why I'm writing a serial loader.
