According to http://e2e.ti.com/support/arm/sitara_arm/f/791/p/384515/1356079.aspx the latency is much higer. For PRU-mapped GPOs there are two cycles (of 200 MHz of PRU), for GPOs accessed via global address space it is even more higher. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
