These are a few of the configurations that is possible on the Embedded Artists EA 2478 board.

Microwin

See MicroWin on EA board

Set your network address at boot

In uClinux-dist/vendors/EmbeddedArtists/rc you can near the bottom set your preferred network address. Find a line looking like this:

ifconfig eth0 192.168.5.233 up

Change the IP address to suit your need and rebuild.

Configuring u-boot

Originally the bootcmd is set to

bootcmd=echo "Booting from NAND FLASH (may take a few secs)." ;run

In order to change this, or other environment variables containing long strings it is recommended to enclose the string in single-quotes (')

setenv bootcmd 'echo "Booting from TFTP (may take a few secs)." ;run tftp_boot'

The usage of single-quotes ensures that the setenv command uses the whole string and not the part up to the semicolon - in the example the bootcmd is set to the first part (the echo string) and the last part is executed immediately.

ssh daemon

NOTE: This description is not complete yet.

dropbear is a drop-in lightweight alternative to the full shh-daemon.

In make menuconfig Network Applications check the dropbear choice.

Unfortunately the version of dropbear supplied with the EA uClinux distribution is not compatible with new ssh-clients. Hence a new version of dropbear must be downloaded and merged into the uClinux source code tree.
