Connect using a terminal emulator to check you can see the correct stub
output coming from the board when it is switched on. It should be something
like
++$T
In GDB make sure you have the correct endianness, using "set endian big".
Also use "set mips saved-gpreg-size 32" as the documentation says.

Nope.

Nope sorry.
