Hi Steve

Thanks very much for your reply.

I do not fully understand the roles of the boot loader and the BSP. In the normal case, would the UPM be programmed by u-boot, or must the kernel also be aware of it?

Specifically, when we talk about Linux BSP, are we talking about the boot loader or the device drivers or both?

Where would I find the UPM table values in the VxWorks BSP?

Sorry, if these are ignorant questions. I am more of an application programmer than a BSP programmer.

Finally, which Linux disctribution and hardware bring-up tools are you using?

Thanks

David
