Page 19: Dbug Boot Loader
Linux on the supported platform (MatchPort AR, XPort Pro, or EDS1100 / 2100) is loaded through two boot loader stages. The first stage is the Lantronix boot loader, which is present on both the Evolution OS and Linux based products. The Lantronix boot loader is marked as read-only, so it cannot be overwritten accidentally. -

Page 27: Supported File Systems Introduction
Introduction Linux supports a wide range of file systems. Most of them were created with certain characteristics in mind: high performance, reliability, compatibility with other operating systems, general purpose, etc. Raw flash devices have inherently different characteristics than block devices such as hard drives and USB flash drives: Flash areas have to get explicitly erased before they can be overwritten Erase blocks, the smallest entities that can be erased on a flash, are usually considerably... -
Page 28: Jffs2
4 Supported File Systems ROMFS being a read-only file system, makes it easy to guarantee its integrity during runtime. On the other hand, all variable data like configuration files that might need to be updated during runtime need to be stored on a separate file system. All applications in ROMFS can be run with XIP: eXecute In Place (set romfs_flash to on in dBug) –... -

If a BOOTP or DHCP server is available on your network you might want to enable CONFIG_IP_PNP_BOOTP or CONFIG_IP_PNP_DHCP as well.
- Page 31 Don't forget to execute “sudo exportfs –av” after modifying /etc/exports. If you do this the first time, make sure that you can mount the exported file system on your host or a different machine on the same network before trying to boot your MatchPort from it. Mounting NFS File Systems During Runtime...

Page 32: Flash Partitioning
Intro to Partitioning The idea of partitioning is to optimize the usage of the available flash space to meet your requirements. A Linux file system encompasses many files with different characteristics. There are binaries and data files. Some of them are crucial for the operation of the system all the time, while some need to be available in certain conditions only. -

It is also more prone to file system corruption of important files then ROMFS, since everything is stored on a single write-enabled partition. On a MatchPort AR it would look like this: 1. Download and flash the kernel image (you can use either linux.bin or the compressed version linuz.bin) -

The default size for the JFFS2 file system is 4MB. It is hard-coded in <install- dir>/linux/vendors/Lantronix/<platform>/config.arch. Since we have 6MB available, we want to make use of it.

µ µ Introduction µClinux supports a full TCP/IP networking stack. Several networking protocols are supported through the kernel and various shell utilities. Networking is initialized on the target through the /etc/netstart script. DHCP The target can obtain an IP address automatically through the DHCP protocol. Two DHCP clients are supported, udhcpc and dhcpcd. -

8 µClinux Networking inetd The inetd program listens for connections to network services such as telnet, ftp, and ssh. The /etc/inetd.conf configuration file specifies the ports to listen to, and their associated programs. The mapping of network port numbers to names is found in /etc/services. telnetd The telnet daemon allows for shell connections over the network. -
Page 51: Busybox
Intro to BusyBox The busybox command incorporates the functionality of several common Linux utilities into a single binary file. The utilities have been optimized for space by supporting fewer options. Flash and RAM space have also been saved by eliminating the overhead of having multiple binary files. Symbolic links to the busybox program are used in place of the utility binaries, as busybox uses the calling link to determine which command to invoke. -

Page 66: Profiling & Debugging Introduction
COMMON_CFLAGS_OPTIMIZE = -0s syslog The syslog daemon is responsible for recording log messages. The Lantronix SDK uses the syslogd functionality provided by busybox. By default the target will write syslog messages in the /var ramdisk partion to /var/log/messages. While syslog is useful for target development, it may be best to disable it on production units in order to reduce memory usage. -

12 Profiling & Debugging iperf The iperf program measures networking throughput between two systems. The program can be run on the target in either client or server mode. If client mode is chosen, iperf must first be run in server mode on the second system. With server mode, iperf must first be started on the target, and then run in client mode on the second system. -
