Other Parts Discussed in Thread: AM4378
I am trying to look at ways to share / transfer data between ARM and PRU (Or in between PRUs). I have looked at a few examples and it looks like I have to use a DRAM that is shared by PRU and the ARM. I had a look at the explanation on this page(http://processors.wiki.ti.com/index.php/PRU_Linux-based_Example_Code#PRU_mem1DTransfer) but I can't find a complete example anywhere. The page pointed to by the above wiki doesn't have any examples.
What I don't understand is how would the PRU and ARM know where to read or write the data? How do I convey that information between the two?
