gdbserver on mips

["Rahul Pande" <rahul.pande@wipro.com>]

Hi,

 

 I am working on a AMD Au1500 based board and want some information. I am using the Linux 2.4.21pre. The problem happens when i run an application under "gdbserver" on the board, it does not allow me to single step into functions/code. The following 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. I would like to know why single stepping support is not there for mips architecture under linux, whereas it is there for others like i386, alpha, arm etc ?

 

Thanks and Regards,

          rahul
