I have tried changing the kernel command line argumnets. I get the same error saying: (All from init/main.c) ---- unable to open an initial console No init found. Try passing init= option to kernel. ----- I am able to debug the kernel on x86 systems. Thanks for all the support. Now I am working with kgdb on mpc8540 board. target kernel version - linux-2.6.13 KGDB version - linux-2.6.13-kgdb-2.3 I am getting the following error: root@localhost sudheer]# /opt/eldk-3.1.1/usr/bin/ppc_85xx-gdb vmlinux GNU gdb Red Hat Linux (6.3.0.0-1.21_1rh) ... This GDB was configured as "--host=i386-redhat-linux --target=ppc-linux"... (gdb) set remotebaud 115200 (gdb) target remote /dev/ttyS0 Remote debugging using /dev/ttyS0 Ignoring packet error, continuing... On the target side, i could see that the target kernel kgdb waiting for host communication. On the target board with kernel version - linux-2.6.13 , I could boot it only after applying the patches: 1. Gain_Phy_update 2.patch-2.6.14-rc5 3.Phy_Platform_Update The patch-2.6.14-rc5 when applied , deleted the file arch/ppc/platforms/pcore.c and pcore.h but the kernel boots well. In the KGDB version - linux-2.6.13-kgdb-2.3 The ppc-lite.patch tries to modify the pcore.c which is not available. I am not sure wether this affects the serial communication establishment. Please help me to solve this.
