Debug user space application with MMU

I am trying to use the gdbserver as described here: http://nioswiki.com/linux/debug_user_space At some point, this was working, but sometimes it wouldn't work and now I haven't had it working...

Hi,

--- Quote Start ---

I am trying to use a core file now. I am running `nios2-linux-gnu-gdb mynios2program`, with set solib-absolute-prefix /data/nios/nios2-linux/uClinux-dist/romfs/ in .gdbinit. Then core-file mycorefile, but all I can get is: 

warning: Couldn't find general-purpose registers in core file.# 0  0x00000000 in ?? ()

Do you have enough space for the core dump file? For example,

ulimit -c unlimiled
