Getting BusyBox
downloading
Get the busybox sources from the busybox site
host$ git clone git://busybox.net/busybox.git host$ cd busybox
compiling
host$ source ~/crossCompileEnv.sh host$ make help host$ make defconfig host$ make -j9 # use -jX for X-1 cores
configuring
You can now configure BusyBox (In the event that none of the graphical tools work you can use "make config" to use the text based tool as a method of last resort). First be sure you have the graphics libraries loaded.
host$ sudo apt-get install libglade2-dev host$ make gconfig
After saving the configuration changes to update the .config file, it is a simple matter of running make.
host$ make -j4
My make took about 1.5 minutes to compile (25 seconds with make -j8!).
installing
Copy it to your Beagle and test it out. Just typing busybox will tell you what commands it knows. Try some of them.
host$ scp busybox root@beagle:. beagle$ busybox beagle$ ./busybox beagle$ ./busybox ls
What's the difference between running busybox and ./busybox? Try some other commands...
