- Subject: [ECOS] GDB question.
Hello,
I am very new at implementing GDB stuff. I have
simulator which can a talk to a GDB host software
throught a serial port. I loaded GDB stubs in my
simulator and called "breakpoint()".
I start my gdb host program, and type the following
(gdb) target extended-remote /dev/ttyS0
Remote debugging using /dev/ttyS0
Couldn't establish connection to remote target
Malformed response to offset query,
T0544:00000000;0e:00000000;
(gdb)
I found the GDB host was sending "+$Hc-1#09" to my
target.
It seems my GDB stub program keep on sending
"T0544:00000000;0e:00000000" string I have no idea
why.
Can someone let me know what are the sequence of
events suppose to happen at the target when the GDB
host request for a connection. By that I mean when the
GDB host type "target extended-remote /dev/ttyS0" what
should be the sequence of response expected from the
target.
Thank you in advance.
Ottawa
