THe interrupt numbers are configured in the IVPRs( Interrupt Vector Proiority Registers). Those registers configure a particular interrupt ( sense, level,enable,vector,priority) The purpose of the vector is to map a physical register to a logical interrupt "channel". Keep those settings, there are good.
> I noticed. And few people use the internal ones :( This doesn'tmatter normally since these UART are fully 16C550 compliant, you can use and I think the code use the standard driver for the 16C550 UART. The only thing that changes is the address of the UART given in the table. The whole description is in the documentation of Motorola Chapter 12 (MPC8245SUM.pdf) You will heve to do some research yourself because the standard driver assume an external UART, so there is also the PCI bus stuff to access it. But normally this should not be a problem with the patch and some experience in driver writing. Try the Montavista patch. It is based on a 2.4.17 kernel and should work since the Hardhat distribution is merely a standard distribution with a custom toolchain.
