Hello,
I'm having trouble to understand the parallel port test (3.1). When we tried a shared access to the LEDs, we got the following error:
Are we supposed to test this access for each processor individually? Or can we simply assign a number of LEDs to one processor and the remaining ones to the other? Or do we need to build a system architecture such that the seperate paraPorts communicate with the shared paraPort, which in turn accesses the LEDs? The latter makes the most sense to me, as it is described in the next step (hardware mutex), but maybe this isn't the idea for the LEDs?
Here is a section of our .qsys implementation with PIO being the shared parallel Port. Thank you for your help.
