I have 3 UARTS -0,1,2 -- Boot the kdb enabled kernel.. but not able to get the --- gdb wait message -- I am setting up an environment for kernel debugging on my MIPS based processor. In whatever document I read there I could get deatails of debugging a PC but not the embedded board. Still i tried to start session which was unsuccessful. Configs enabled: CONFIG_KGDB=y CONFIG_KGDB_CONSOLE=y CONFIG_KGDB_8250_NOMODULE=y CONFIG_SYS_SUPPORTS_KGDB=y and I can see the change in size of the vmlinux. while booting I have given command parameters : boot -z -elf "kgdb8250=1 115200" kgdbwait ------ but my kernel is not waiting for remote gdb to wait for the connection. Am I missing anything ? Help me to set it up ... I had put pritnks I am getting KGDB : kgdb_late_entry .. KGDB: kgdb_arch_init ..... KDGB: kgdb_internal_init .... KGDB: Setting kgdb_initialized .. but normally going to login prompt ... when I press ^C -- Breakpoint is catched -- then everyting come to halt .. Thanks prabhu
