Which toolkit version is it? If you type "mips64vr4300-elf-gcc -v" what
does it output?

If you've bought the product, did it include support? If so, it may be

Have you programmed the board with a new boot ROM? I believe the boards
from NEC come with PMON as the boot ROM, but if you want to have debugging
support you will need to program a GDB stub boot ROM. You may want to read
