Start IDE New Project, PowerBrick_LV makefile and output at: C:\Documents and Settings\user\Desktop\scratch\PowerBrick_LVUserServoLoop\PowerBrick_LVUserServoLoop\C Language\Realtime Routines
Update Firmware
we are using: 2.0.2.14, IDE wants newer, probably 2.1.1.3 (http://forums.deltatau.com/filedepot/) With IDE the new firmware can be installed (tools->...->download firmware)

The sources are from C:\Documents and Settings\user\Desktop\scratch\PowerBrick_LVUserServoLoop\PowerBrick_LVUserServoLoop\C Language\Realtime Routines The Makefile was build with informations from the .../Realtime Routines/.usralgo.o.cmd etc. files
rootfs files are on the powerbrick or in C:\DeltaTau\Power PMAC IDE\compilers\opt -> powerpc-465-rootfs.tar.gz On the powerbrick the kernel sources are not installed -> therefore the rootfs from the IDE is needed
Make usralgo.ko
Sample Kernel Module
