Someone just asked me about this and I realized other people might find it useful. In your Makefile, CFLAGS_KERNEL = -g -gdwarf rw> load image zImage.treeboot <--- loads zImage onto target rw> load host vmlinux <--- loads debugging info into RISCWatch That's almost all it takes. Unfortunately RISCWatch will try to open unqualified filenames, e.g. "rd.c". So you have to add to your srchpath all the directories you're interested in: rw> srchpath add /home/hollis/src/linux/arch/ppc/platforms rw> srchpath add /home/hollis/src/linux/arch/ppc/kernel rw> srchpath add /home/hollis/src/linux/kernel ...... I did this in my startup.cmd file by starting with a `find -type d` and trimming from there. Current (5.0) versions of RISCWatch claim to support dwarf2 which is now the default debug format in gcc 3.x, but gcc 3.x added some extentions that RW doesn't understand, so the load fails. I tried dwarf1 with gcc 3.x, but that fails to compile due to gcc bugs. The recommendation was made to use gcc 2.95 with dwarf2, but that just caused RW to segfault. I'm using dwarf1 with gcc 2.95 and that's working. -Hollis ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
