I am using the AM5729 (Beaglebone AI) for some real time programming on the PRU cores. Communication and data sharing between PRU cores in the same PRU-ICSS is possible - using shared memory, interrupts etc. - but is there any similar method for communicating with PRU cores in the other PRU-ICSS without having to go via the CPU? My application would ideally use all 4 PRU cores with direct communication and memory sharing between all 4.
