- Subject: [ECOS] Debugging using serial port
Hi All,
We tried to debug an application thru the serial cable. We connected our
i386-pc target's COM1 to our Linux host's COM1(/dev/ttyS0).
We have used i386-elf-gdb. We ran the commands:
(gdb) set remotebaud 38400
(gdb) target remote /dev/ttyS0
Remote debugging using /dev/ttyS0

When we use -
set remote debug 1, I get the following output...
Sending packet: $Hc-1#09...Sending packet: $Hc-1#09...Sending packet:
$Hc-1#09.. Sending packet: $Hc-1#09...Timed out. Timed out. Timed out.
Ignoring packet error, continuing... Sending packet: $qC#b4...Sending packet:

Please help us out to enable serial debugging using redboot.
Thanx,
Nikhil
