These are the startup options for beginning your GDB session with a Nindy-960 board attached:
-r
porttty
(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.
