Julian, We are doing a project here at work with that board. Are you using the NEC Osprey? The board is a POS. Watch out for the voltage buffers on the extern ISA ports not being able to handle the speed of the ISA bus if the board isn't warmed up. Get your heat gun if you're plugging in any hardware to it. For building your cross compiler (you will want to use mipsel, which is 32. Don't do 64 bit stuff on the 4181. You'll never need it) please see http://www.ltc.com/~brad/mips/mips-cross-toolchain/ which is a great guide. Take care not to overwrite your PC's libs with mips ones. Ouch. :) I'm happy with this processor although it is a bit slow. I managed to get worst case interrupt latency at 46 microseconds with linux going full blast on network and compact flash stuff with our external board. (using RTAI and kernel 2.4.18) Steve >-----Original Message----- >From: linux-mips-bounce@linux-mips.org >[mailto:linux-mips-bounce@linux-mips.org]On Behalf Of Julian Scheel >Sent: Wednesday, February 12, 2003 9:23 AM >To: linux-mips@linux-mips.org >Subject: NEC VR4181A > > >Hello all, > >I need a bit help.
