This is the first time i use bdi for kernel debugging. ELDK 3.0 is my toolchain (Target 8270). My bdi2000 can sync with the gdb (ddd) debugger. I let the kernel run until "start_here", at example. Then i try to step through the source. I see the source and i can step in it. Sometimes it happens that i spend a lot of time in linux/kernel/timer.c. Then the output of gdb is " (gdb) next Single stepping until exit from function __cli, which has no line number information. Program received signal SIGSTOP, Stopped (signal). 0xc0007dec in __cli ()" The same output with "step". "Cont" ends also there, although i had set a breakpoint later in the source. Are there some options in the kernel or in the gdb to set ?
