Hi all,
i have some problems with debugging my kernel. 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 ?
Thanks in advance
Marco

Marco,
Please look online at the Ultimate Solutions website, I documented this
issue a little while ago, http://www.ultsol.com/faq-P305.htm. Wolfgang made
the right suggestion, using BDI_CONFIG_SWITCH will cure this problem.

But my kernel has this option.
