hi,
       i am working on i386 based board and want some information. i am using mips-linux 2.6.6 kernel on target board and linux 2.6.9 on intel board. I am running an application under "gdbserver" on the target mips board, but am not able to do a single step inside the function. Foll. error is displayed
          "ptrace : Input/Output error",

   the  "ptrace.c" file under arch/mips/kernel/ does not have support for PTRACE_SINGLESTEP because of which the above error is occuring. Though i386,alpha,arm etc. architecture has this support, but why mips doesnt have this ?
 
   I am not a member of this group, so kindly reply me on my personal id.

Regards,
Mehul.

Because the hardware doesn't.  GDB doesn't need it, either.  It sounds
like your GDB is not correctly configured for mips-linux.
