7/11/08 Problems Found

I generated a device tree and found the following problems with it.

1. I had to add "console=…." to the boot args
2. I had to manually add this to the device tree, linux,stdout-path = "/plb@0/serial@83e00000";
3. timebase-frequency = <0>;

• This should not be 0, but should be the frequency the processor is running at, typically 300000000 for 405 processor or 400000000 for 440, depending on your hardware design.
