The old UIO drivers had access to the prussdrv_map_extmem function which could be used to expose DDR3 memory to the pru, and prussdrv_get_phys_addr which could be used to communicate where the PRU should access data. This is useful when you want to transfer large amounts of data between the PRU and the ARM core. This can be seen in action here <https://github.com/google/prudaq/blob/8ef53f45aab16a095edc50d1e144e191d13303c1/src/prudaq_capture.c#L147> .
Is the same functionality available in the newer pru_rproc drivers? If not, what's the best way to do about doing large transfers between the PRU and the ARM core? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
