The CPU can access the PRU resources, so you don't need to write PRU code if you don't want. But access has to go through the PRU interconnect fabric, and is likely to be slower than the more traditional SoC UARTs and timers. See section 3.2 'Global Memory Map' in the PRU Reference guide for addresses to use from the host (ARM) side. -- Charles Steinkuehler [email protected] -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
