Hi folks, right now I am trying to get the the PRU with the remoteproc-driver run. It ist working quite well, but there is one Problem which I dont now how to solve it.
I am trying to use the shared Memory between the ARM and PRU. 4a310000 startig adress. My Problem is that in my application I want to write data to the shared memory and afterward start the PRU-Core and read put the data. I am writing with a c-Programm with mmap. It works good and I can read out the data after I wrote it to the RAM. I am using the devmem2 -tool from DerickĀ“s Exploring Beaglebone Book. No my main problem. After I wrote my data to the shared RAM and start the PRU-Core (changing the state of the remoteproc-driver) all my data is gone and in the shared Memory just zeros exist. My question is, why is the driver writing just zeros to the shared memory when starting the PRU-Core. And is the any possibility to avoid this process of initilaizing all the shared memory? Do you have any ideas? Why and how this happens?
