BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts. BusyBox provides a fairly complete environment for any small or embedded system.
 
BusyBox has been written with size-optimization and limited resources in mind. It is also extremely modular so you can easily include or exclude commands (or features) at compile time. This makes it easy to customize your embedded systems. To create a working system, just add some device nodes in /dev, a few configuration files in /etc, and a Linux kernel.

Gateway 6 application

Preparations

Connecting to gateway through serial console

  1. Connect Gateway to your computer
  2. Open up a terminal: gnome-terminal / ssherminator / xterm / any other
  3. Start minicom
    • Settings: 38400 8N1 flow control: none
  4. Connect external power to gateway
  5. Press any key when asked
    • You will only have a second

You will see(With DIMM module 27M-DMM-144):

Hit any key to stop autoboot:  0 
u-boot>

Voila, you're in console

Setting up U-Boot

To see current environment variables type

  • printenv

It returns something like this:

u-boot> printenv
bootdelay=3
baudrate=38400
bootcmd=one read a1000000 40000 160000;wtags;go
ethaddr=00:0d:15:00:72:31

netmask=255.255.255.0
serverip=10.0.0.16
ipaddr=192.168.1.200
bootargs=console=ttyS0,38400 tftproot=10.0.0.16:rootfs.tar.gz
gatewayip=10.0.0.42

Environment size: 279/2044 bytes
u-boot> 

Now:

  • set gatewayip 10.0.0.42
  • set ipaddr 10.0.0.23
    • this needs to be unused, ping it if unsure
      • ping 10.0.0.23
  • save

Flashing filesystem

  • Set up tftp server on your computer
  • Connect gateway to network
  • Paste to u-boot
u-boot> erase 1:12-;set bootargs console=ttyS0,38400 tftproot=10.0.0.16:rootfs.tar.gz;tftp zImage-144u.bin;wtags;go
  • Restart device when asked

When it doesn't work

Warning: gatewayip needed but not set

While in U-Boot type:

  • Set gatewayip 10.0.0.42
  • Save
