These are the startup options for beginning your GDB session with a Nindy-960 board attached:
-r
port
-r /dev/ttya
), a
device name in /dev
(e.g. -r ttya
), or simply the unique
suffix for a specific tty
(e.g. -r a
).
-O
Warning: if you specify -O
, but are actually trying to
connect to a target system that expects the newer protocol, the connection
fails, appearing to be a speed mismatch. GDB repeatedly
attempts to reconnect at several different line speeds. You can abort
this process with an interrupt.
-brk
BREAK
signal to the target
system, in an attempt to reset it, before connecting to a Nindy target.
Warning: Many target systems do not have the hardware that this requires; it only works with a few boards.
The standard -b
option controls the line speed used on the serial
port.
