I If you have a Linux Ethernet driver working, then most people boot and mount with an NFS root disk. Then you just cross-compile additional apps and tools and adding to your NFS disk. Presumably including gdb (not tried it). Then just debug "normally" -- with the CLI. The JTAG hardware debugger is not used (or maybe just to initially bootstrap the kernel and trap certain exceptions). RH7.1 fs at: ftp://ftp.linux.sgi.com/pub/linux/mips/mipsel-linux/root/ And see: http://www.linux.sgi.com/downloads.html Once your basic apps are complete, then you can think about creating a JFFS2 partition (after the MTD flash driver's debuggged) and using that for standalone bootup. Actually, my first approach was to flash the linux kernel with just a cramfs'd busybox and then NFS mount my home directory from a startup script. To save (a lot of) space in applications checkout uclibc.org. Shared libs support with uclibc is real close for MIPS, but for now use static linking. Geoff -- Geoffrey Espin espin@idiom.com --
