Книга: Embedded Linux development using Eclipse

5.4.1 System Requirements

5.4.1 System Requirements

The following hardware and software components are required in order to work through the example in this section:

• Target embedded computer board with network and serial ports. The example here is based on a board available from Intellimetrix. See Appendix B, “The Embedded Linux Learning Kit,” for details on this board and how to obtain it. A nice feature of this board is that it includes a temperature sensor for the thermostat example.

• Serial and network ports on the host workstation.

• GCC cross tool chain for the target board.

• NFS server running on the host machine.

• minicom terminal emulator for communicating with the target board’s serial port.

• TFTP server is useful but not required.

All of the software components with the exception of the cross tool chain should be part of any decent Linux distribution. The tool chain should be available from the target board vendor.

The other approach to a target environment for the purpose of this chapter is to make use of an old 486 box that’s sitting in the closet or serving as a doorstop. Put a network card in the box and install Linux on it. Redirect stdin, stdout, and stderr to a serial port. In this case you don’t need a cross compiler. The one you’ve been using is quite sufficient.
