UC-7110 Series User’s Manual Getting Started Telnet If you know at least one of the two IP addresses and netmasks, then you can use Telnet to connect to UC-7110’s console. Default IP Address Default Netmask LAN 1 192.168.3.127 255.255.255.0 LAN 2 192.168.4.127 255.255.255.0 Telnet can be used locally by using a cross-over Ethernet cable to connect your computer to UC-7110, or over a LAN or the Internet. The default IP addresses and netmasks are shown above.
UC-7110 Series User’s Manual Getting Started Configuring the Ethernet Interface In this section we use the serial console to explain how to modify UC-7110’s network settings. 1. Change directories by issuing the command cd /mnt/etc. 2. Type the command vi rc to use VI Editor to edit the configuration file. The IP addresses for UC-7110’s LAN1 and LAN2 are given as ifconfig eth0 192.168.3.127 ifconfig eth1 192.168.4.127 as shown in the following figure.
UC-7110 Series User’s Manual Getting Started 3. You may also configure UC-7110 to request IP addresses from a DHCP server. In this case, use the sharp sign (#) to comment out one or both “ifconfig” lines, and then delete the sharp sign in front of the “dhcpcd” lines, as shown below. Note that UC-7110 will send out DHCP broadcast packets, and then get the IP addresses from the first DHCP server that responds. 4. Issue the vi “write” command to save the file, and then reboot.
UC-7110 Series User’s Manual Getting Started Developing Your Applications Step 1: Connect UC-7110 to a Linux PC. Step 2: Install Tool Chain (GNU Cross Compiler & uClibc). Step 3: Configure cross compiler and uClibc environment variables. Step 4: Code & compile your program. Step 5: Download program to UC-7110 via FTP or NFS. Step 6: Debug the program. If the program is OK, proceed to Step 7. If the program needs to be modified, go back to Step 4.
UC-7110 Series User’s Manual Getting Started Compiling Hello.c The Tool Chain path is: PATH=/usr/local/arm-elf/bin:$PATH The UC-7110 CD includes several example programs. We use Hello.c to illustrate how to compile and run applications. Issue the following commands from your PC to compile Hello.c: # cd /tmp/ # mkdir example # cp –r /mnt/cdrom/example/* /tmp/example Go to the Hello subdirectory, and then issue the command #make to compile Hello.c. Finally, execute the program to generate hello and hello.
UC-7110 Series User’s Manual Getting Started Uploading “Hello” to UC-7110 To use FTP to upload hello to UC-7110, issue the following commands from the PC side: #ftp 192.168.3.127 ftp> cd /home ftp> bin ftp> put ./hello ftp> quit #telnet 192.168.3.
UC-7110 Series User’s Manual Getting Started Running “Hello” on UC-7110 To run the “Hello” program issue the following commands from the UC-7110 side: # chmod 755 hello #./hello The words “Hello World” will be printed on the screen. ATTENTION Be sure to calculate the amount of Flash Memory used by the User File System in the Flash ROM.
UC-7110 Series User’s Manual Getting Started Make File Example Code The following Makefile file example codes are copied from the Hello example from UC-7110’s CD-ROM. # Generated automatically from Makefile.in by configure. # $Id: Makefile.in,v 1.59 2002/03/24 22:20:19 jnelson Exp $ .SUFFIXES: .SUFFIXES: .o .c .
UC-7110 Series User’s Manual Getting Started ATTENTION There is another example that involves modifying the Makefile. If the target source code file is tcps1.c, then users should modify at least 4 places to replace hello with tcps1. Copy the Hello example’s Makefile to your source code target directory, and then modify it to work with your program. After that, follow the procedures outlined in the previous sections: Compiling Hello.c, Uploading “Hello” to UC-7110, and Running “Hello” on UC-7110.

UC-7110 Series User’s Manual Software Package UC-7110 Software Architecture The pre-installed µClinux Operating System used by UC-7110 follows the standard µClinux architecture, making programs that follow the POSIX standard easily ported to UC-7110 by using the GNU Tool Chain provided by www.uClinux.org. In addition to the Standard POSIX API, device drivers for the buzzer, and UART for the serial ports are also included.
UC-7110 Series User’s Manual Software Package and uses JFFS2 for the User Directory. The partition sizes are hard coded into the kernel binary. You must rebuild the kernel to change the partition sizes. The flash memory map is shown in the following table.
UC-7110 Series User’s Manual Software Package Although JFFS2 is a journaling file system, this does not preclude the loss of data. The file system will remain in a consistent state across power failures, and will always be mountable. However, if the board is powered down during a write, then the incomplete write will be rolled back on the next boot. Any writes that were already completed will not be affected. Additional information about JFFS2 is available at: http://sources.redhat.com/jffs2/jffs2.

C FAQ for UC-7110 Appendix C FAQ 1 Why can I only use vfork( ),and am unable to use fork( )? Answer 1 uClinux only supports vfork( ). It does not support fork( ). Note that when using vfork( ), the parent process will hang until the son process calls an exec group API, or exits.
UC-7110 Series User’s Manual FAQ for UC-7110 FAQ 5 How do I compress an application program? Answer 5 UC7110’s kernel supports ZFLAT format files. This means that when you compile the program, you can add the compress option to reduce the size of the binary file. Doing so will reduce the required flash space on the user disk. The disadvantage of using the compress option is that it takes about 5% to 10% more time when loading the program from Flash to RAM.
