The amit company made some modifications to Busybox-1.0-rc2. The purpose of this modifications were:

• Set the hardware clock with the proprietary amit lib
• Include libamit in the build script
• Let the leds flash on shutdown
• Print CPU-usage for every process in ps

It seems that the other utilities on the initrd do not depend on CPU-usage feature. Because of that and because it was the biggest part of the patch, this was not included. The other changes, including and a bugfix, which prevents a write to a random memory address, are included in the patch below.

To create a flash-image with Busybox-1.7.2 replace the contents of busybox_src in the MGB100_\GPL folder with the sources of Busybox-1.7.2. After that cd into that directory and apply the patch. Now you have to configure busybox. After that you can build the flash-image from the MGB100_\GPL folder with make linuxall

If you want to test busybox before you flash the new image have a look at Temporary modifications to the initrd
