Where did you get your toolchain source from? I think the GDB on
OpenCores checks the UPR register incorrectly (i.e., checks the wrong
bit), reporting that the debug unit isn't present even though it is.
You could give my toolchain a try
(http://www.eecg.utoronto.ca/~jarvin/or32/) -- the or32-elf-gdb and jp2
in there work for me. Or, check your GDB source against the OR1200
architecture manual.
