Hi, I'm new to this list. Excuse me if my questions sound too trivial.
I'm getting the following error messages. ---------------------------------------------------------- Test Machine(MIPS) --> RedBoot> fis load -d vmlinux Image loaded from 0x80060000-0x80291085 RedBoot> exec -c "kgdb8250=0,115200 root=31:02 rootfstype=jffs2 init=/sbin/init" Now booting linux kernel: Base address 0x80050000 Entry 0x80256000 Cmdline : kgdb8250=0,115200 root=31:02 rootfstype=jffs2 init=/sbin/init Development Machine(x86) --> # gdb ./vmlinux GNU gdb Red Hat Linux (6.1post-1.20040607.43.0.1rh) Copyright 2004 Free Software Foundation, Inc.

Test machine runs "mips-linux-2.6.15" cross-compiled on my development machine. I couldn't find KGDB patch for mips-linux-2.6.15 :( so I used linux-2.6.15.5-kgdb-2.4.tar.bz2 KGDB patch for test machine. ---------------------------------------------------------- Questions: 1. Is my setup correct? Do i have to use development and test machines of same architecture? MIPS platform is still supported or not? 2. I'm using a Serial to USB converter, is it fine or I have to use a null modem cable only? 3. I believe I'm not using a right KGDB patch, is it so? ---------------------------------------------------------- .config files I tried --> 1. # Kernel hacking # CONFIG_DEBUG_KERNEL=y ....... CONFIG_DEBUG_INFO=y CONFIG_WANT_EXTRA_DEBUG_INFORMATION=y CONFIG_KGDB=y CONFIG_KGDB_CONSOLE=y CONFIG_KGDB_8250_NOMODULE=y CONFIG_CROSSCOMPILE=y CONFIG_CMDLINE="" ---------------------------------------------------------- 2. # Kernel hacking # CONFIG_DEBUG_KERNEL=y ....... CONFIG_DEBUG_INFO=y CONFIG_WANT_EXTRA_DEBUG_INFORMATION=y CONFIG_KGDB=y CONFIG_KGDB_CONSOLE=y CONFIG_KGDB_ONLY_MODULES=y CONFIG_CROSSCOMPILE=y CONFIG_CMDLINE="" ---------------------------------------------------------- Command line options I used during kernel booting at test machine: 1. Cmdline : kgdb8250=0,115200 root=31:02 rootfstype=jffs2 init=/sbin/init 2. Cmdline : kgdb8250=0,115200 kgdbwait root=31:02 rootfstype=jffs2 init=/sbin/init 3. Cmdline : console=ttyS0,115200 root=31:02 rootfstype=jffs2 init=/sbin/init 4. Cmdline : console=ttyS0,115200 kgdbwait root=31:02 rootfstype=jffs2 init=/sbin/init None of the above solved my problem. ---------------------------------------------------------- I also tried using different BAUDRATES but no success there too. Any help or pointers on this would be great. Thanks Amit Pundir ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
