You can use the E7000 in-circuit emulator to develop code for either the Hitachi H8/300 or the H8/300H. Use one of these forms of the `target e7000' command to connect GDB to your E7000:
target e7000 port speed
target e7000 hostname
telnet
to connect.
The monitor command set makes it difficult to load large ammounts of
data over the network without using FTP. We recommend you try not
to issue load
commands when communicating over Ethernet; use the
ftpload
command instead.
