There's two problems here:
1. You're running the code in a simulator -- the simulated or32 code has
no clue about the x86 OS/filesystem that the simulator operates in.
2. The or32-elf toolchain in the drp-0.6 tarball only implements a stub
for open() that returns ENOSYS (no filesystem!). read() and write()
route stdin/stdout/stderr to the UART and return an error if any other
descriptor is passed in. See
drp-0.6/toolchain/src/newlib-1.15.0/libgloss/or32/io.c.
Writing to a file is out of the question. Why not dump your data to stdout?
