These are a few of the configurations that is possible on the Embedded Artists EA 2478 board.
Microwin
ssh daemon
dropbear is a drop-in lightweight alternative to the full shh-daemon.
In make menuconfig Network Applications check the dropbear choice.
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 upChange 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.
