Hello,

I've successfully ported U-Boot to the Motorola PrPMC800. Support for FLASH, PCI, IDE and networking have bee successfully enabled. It has been in use now for several weeks in a stable form. I do have one lingering problem of not being able to turn on the L1 and L2 data caches. Doing so apparently causes the system to hang. Unfortunately I don't have a BDI2000 setup for this board to better debug the problem. I used just a good ol' console and plenty of printf statements to do the port.

I can't give a specific time for when I will have the port submitted for a future release of U-Boot. But I will do it. I'd like to fix my cache problem first and I have to finish the rest of the project for which U-Boot is just one part. And that may be awhile.

Regards, Mark.

Hello,

My name is Mark Lightfoot and I'm a software engineer with SITA INC. I'm investing the possibility of porting U-Boot to the Motorola PrPMC800 and possibly the Force Computer PowerPMC-260.

As anyone already done the port to these boards?

See URL: http://mcg.motorola.com/cfm/templates/product.cfm?PageID=925&ProductID=1... And URL: http://www.forcecomputers.com/products/viewDetail.cfm?productTypeID=2&pr...

The goal is to boot Linux from and IDE drive which the boot firmware of these boards do not support. I don't have the Motorola hardware yet ( delivery is six to eight weeks! ) but it is the intended hardware for the project I'm working on. I do have the Force Computer hardware right now. So, I may proceeded to port U-Boot to it first and do my the remainder of the Linux development work with it in the mean time.

Brgds, Mark.
