Hey, I am using an OMAP L138 experimenter kit running embedded Linux (DaVinci PSP release 3.21.00.04), and I have been trying to figure out how to set up UART1 port. From looking at the kernel source code it seems as if UART1 is enabled by default in this release. I am wondering if there is a standard way to modify the registers on the L138 in order to set up some initializations/change pin mux settings. From the research I have done so far, it seems as if this can be done by either modifying the kernel source code and rebuilding it, or by creating and installing a kernel module which would allow me to access the registers from the user space, as if I was writing to a file. I have no experience doing either of these and not a lot of experience with Linux in general. I would really appreciate an explanation of how to do either of these methods, or at least someone to point me in the right direction so I don't waste my time with the wrong method.
Thanks,
Matt
