- First Steps INTRODUCTION The Starter Kit eSOM/SK2 contains everything you need to get started with your embedded networking application. The Starter Kit includes an eSOM/9263 module with a pre-installed U-Boot boot loader and an embedded Linux, the Evaluation Board BB6/eSOM, power sup- ply, serial interface (null modem) cable, a CD-ROM with software and documentation and a printed user manual for the first steps with the Starter Kit.
- First Steps Features and Technical Data The eSOM/SK2 comes with a pre-installed U-Boot boot loader and an Embedded Linux op- erating system. The eSOM/9263 Linux consists of two main components: 1. the Linux ker- nel and 2. the root file system.
- First Steps GETTING STARTED Serial Link between BB6/eSOM and PC Setup the serial link between the Evaluation Board BB6/eSOM and your PC. Use a null mo- dem cable for this connection. Figure 1: Serial link between BB6/eSOM and PC Connect one end of the null modem cable with an unused COM port of your PC.
- First Steps Ethernet Link between BB6/eSOM and PC Setup the Ethernet LAN link between the Evaluation Board BB6/eSOM and your PC. Use an Ethernet cross-over cable or a switch-based infrastructure for the LAN connection. Figure 2: Ethernet link between BB6/eSOM and PC Please note: The eSOM/9263 comes with the default IP address 192.168.0.126.
- First Steps Connecting Power Supply and Power-up the Starter Kit Connect the 12 VDC power supply with the barrel plug with the Evaluation Board BB6/eSOM. Please note: Make sure that all cable connections are OK. Then power-up the Starter Kit.
- First Steps Using Serial Link with Terminal Program Run HyperTerminal on your Windows-PC, minicom or a similar simple terminal emulation program on your Linux-based PC. Figure 5: Direct connection setup with HyperTerminal Setup a direct connection with the parameters of table 2. Make sure, that the PC COM port supports 115.200 bps.
- First Steps Power-up eSOM/9263 with RCM disabled After power-up the eSOM/9263 starts an automatic boot process from the on-board flash memory chip. This process consists of two steps: 1. Directly after power-up, the eSOM/9263 runs the U-Boot boot loader program for some milliseconds.
- First Steps Power-up eSOM/9263 with RCM enabled The eSOM/9263 boot sequence with RCM enabled is similar to the boot procedure with RCM disabled. Only the first step is different: 1. The eSOM/9263 runs the U-Boot boot loader program. This software shows a wait message over the eSOM/9263 COM1 serial interface if RCM is enabled (please see the eSOM/9263 hardware reference manual for details).

- First Steps eSOM/9263 Linux File System After booting the eSOM/SK2 all directories in the root file system are read-only. There are only three exceptions, which are shown in the following table: Directory Remark /flash R/W directory, non-volatile memory within Flash...
- First Steps Checking IP Address of PC Make sure that your PC is using the right IP address for the Ethernet-based TCP/IP com- munication with the eSOM/9263. Please use 192.168.0.1 or 192.168.0.254 for your PC and 192.168.0.126 for the eSOM/9263.
- First Steps Checking Ethernet-based TCP/IP Communication Check the Ethernet-based TCP/IP communication between the eSOM/9263 and the PC with a simple ping command. Figure 13: Windows-PC TCP/IP communication check with ping First check the cable connections and then the IP addresses if your ping does not work.
- First Steps 2.10 Using a Telnet Connection Run a Telnet client program on your PC with the IP address of the eSOM/9263. You can use a Telnet session for remote entering Linux commands. Figure 14: Run the Windows Telnet client program Wait until the eSOM/9263 Linux requests a user name.
Checking FTP Server The eSOM/SK2 Linux comes with a pre-installed FTP server. This server allows the file transfer via Ethernet between a PC and the eSOM/SK2. Run an FTP client program like FileZilla on your PC for a test. Figure 16: FileZilla as FTP client to access the FTP server Use for the FTP login the IP address 192.168.0.126, the username root and the...
2.12 Checking TFTP Client The eSOM/SK2 Linux comes with a pre installed TFTP client. This client allows the file transfer via Ethernet between a PC and the eSOM/SK2. Run a TFTP server like TFTPD32 on your PC for a test.
The browser shows the file index.html which is stored in the directory /www of the eSOM/SK2. Into this directory you can load own files. Figure 18: Checking the Web server of the eSOM/SK2 with a browser...
2.14 Changing Ex Factory IP Address The default IP address of the eSOM/SK2 is 192.168.0.126. The IP address settings are stored in the file /etc/network/interfaces. Run a Telnet session and start the editor nano which is part of the Linux with the following command:...
