A Hitachi SH, H8/300, or H8/500 board, attached via serial line to your host.
Use special commands device and speed to control the serial
line and the communications speed used.
target e7000 dev
E7000 emulator for Hitachi H8 and SH.
target sh3 dev
target sh3e dev
Hitachi SH-3 and SH-3E target systems.
When you select remote debugging to a Hitachi SH, H8/300, or H8/500
board, the load command downloads your program to the Hitachi
board and also opens it as the current executable target for
GDB on your host (like the file command).
GDB needs to know these things to talk to your
Hitachi SH, H8/300, or H8/500:
that you want to use `target hms', the remote debugging interface
for Hitachi microprocessors, or `target e7000', the in-circuit
emulator for the Hitachi SH and the Hitachi 300H. (`target hms' is
the default when GDB is configured specifically for the Hitachi SH,
H8/300, or H8/500.)
what serial device connects your host to your Hitachi board (the first
serial device available on your host is the default).
