E7000 in-circuit emulators

You can use the E7000 in-circuit emulator to develop code for either the Hitachi H8/300 or the H8/300H. Use one of the following forms of the target e7000 command to connect gdb to your E7000.

target e7000 port speed
Use this command if your E7000 is connected to a serial port. The port argument identifies what serial port to use (for example, com2). The third argument, speed, is the line speed in bits per second (for example, 9600).

target e7000 hostname
If your E7000 is installed as a host on a TCP/IP network, you can just specify its hostname; gdb uses telnet to connect.

The monitor command set makes it difficult to load large amounts of data over the network without using ftp. We recommend you try not to issue load commands when communicating over Ethernet; instead, use the ftpload command.
