NicheStack for LM3S9B90

The NicheStack for LM3S9B90 product includes the InterNiche NicheStack TCP/IP Stack, HTTP Server, FTP Server, Telnet Server, and DHCP Client. The target platform is the EK-LM3S9B90 Stellaris Evaluation board.

Loading the Software

To download the NicheStack software to the Evaluation Board, please follow these steps. The Evaluation Kit Quickstart documentation provides additional information on the board's setup and operation.

  1. Unzip the NicheStack software onto the Host PC.
  2. Connect a USB cable between the Host PC and the Evaluation board. Connect a ethernet cable between the Host network and the Evaluation Board.
  3. Download the nichestack.bin file to the Evaluation Board using the LM Flash Programmer utility program available from the TI / Luminary Micro website (
  4. Configure a terminal emulator program, such as HyperTerminal, to communicate with the virtual COM port of the Evaluation Board. The COM port should be set to: 115200 baud, no parity, 1 stop bit, and no flow control.
  5. Press the Reset button on the Evaluation Board to reset the board and start the NicheStack software. The output from the NicheStack software initialization will appear in the Terminal emulator window, followed by the NicheTool "INET>" prompt.

Notes about the NicheStack software:

  1. The software attempts to obtain an IP address via DHCP. If there is no DHCP server available, the default is:
    IP address:
    Subnet mask:
    MAC address:  
  2. The web server can be accessed by setting a web browser, such as Internet Explorer or Mozilla's Firefox, to the URL: (or the IP address obtained from the DHCP server).
  3. The FTP server can be accessed by a FTP client running on the Host PC. The NicheStack Virtual File System contains several large files for use in evaluating data transfer performance. A typical FTP sequence might be:
    $$ ftp
    User: guest
    Password: guest
    ftp> dir
    ftp> binary
    ftp> get mem2M mem2M
    ftp> put mem2M null
    ftp> quit
  4. A Telnet client running on the Host PC can access the Telnet Server using the login name 'guest' and password 'guest'.
  5. The NicheStack software has a one-hour time limit. After one hour, the software will stop and the Evaluation Board will need to be rebooted.
