I don't think there's a specific NOP, but since the PRU doesn't have flag bits (except for carry) to worry about, you can alias any of a number of instructions to be a NOP: AND r1, r1, r1 OR r1, r1, r1 XOR r1, r1, 0 MOV r1, r1 ...and so on. -- Charles Steinkuehler char...@steinkuehler.net -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
