I have the same question. I'm using the PRU's 200 MHz cycle counter to timestamp sensor measurements. At 200 MHz, this 32-bit counter overflows in 20 seconds. I would like to notify a C program running on the 1GHz host ARM processor as soon as it overflows.
*Is it possible to configure the PRU cycle counter to trigger an interrupt in the host ARM when it overflows?* I know how to write PRU code to make the PRU trigger an interrupt in the host, but that's not quite what I want, since my PRU will be busy doing other things. I would like the cycle counter to trigger an interrupt automatically, without the PRU having to check if it has overflowed. Many thanks! -Justin On Saturday, December 17, 2016 at 3:06:08 PM UTC-8, Amr Alanwar wrote: > > HI All > > Is there a way to get an interrupt when there is PRU cycle counter > overflow ? > > Thanks > -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
