Objectives

• To enable the students to write real test programs in SVF and to execute online

• To provide a tool for test program validation

• To facilitate hands-on sessions with real 1149.X hardware

Outline

• The test setup– The micro web server board– IP address and connections

• The MWS-TAP application– Set IP address and connect– The SVF test program– Example

Setup: The MWS board

• The micro web server TAP controller application uses a DSTINIm400 networked microcontroller evaluation board (Maxim-Dallas)

• The current prototype controls one BS chain

Setup: IP and connections

• Use the MWS RS232C connector and the MTK tool to program a valid IP address into the micro web server board

• Use FTP to load the server application into the MWS board and Telnet to launch theserver process

Set up (cont.)

• If the current IP of the MWS is known, a quicker set up procedure is possible:– Connect the card directly to a computer using a

regular LAN cable and telnet to its IP address– Set up the new IP address (cuts the current

connection if in different subnets), e.g. ipconfig -a 158.36.164.12 -m 255.255.254.0 -g 158.36.164.1

– Set the current IP of the computer to the same subnet and reconnect (or use the LAN)
