<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Could you return ‘\0’ for “qTStatus”?
It seems gdb asks gdbserver trace point status on break-in. qTStatus is one of
them. I believe kgdb stub returns ‘E’ for “qTStatus”. I
am asking you to return ‘\0’ instead of ‘E’. If kgdb
stub returns ‘\0’, gdb works fine with Linux kgdb without
modification on gdb at least break-in, continue and quit.<o:p></o:p></span></font></p>

<br>
Is it the case that the kgdb stub should be responding with some sort of<br>
message?<br>
<br>
Certainly we are always open to improving the kgdb side too.<br>
