I see up to 5.8 microseconds of latency when the PRU is reading from DDR memory. Is it possible to reduce this? I tried changing registers that looked promising for giving the PRU priority but they didn't have a noticeable effect. This is running on a Beaglebone black using a PRU timer to measure the maximum time a LBBO from DDR takes.while the ARM is busy.
The examples I found for doing DMA from the PRU were all for older kernels and wouldn't work with Linux 3.8.13. Is there an example I missed that works with this kernel? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
