OK, great! So exactly which firmware are you using? In my docs, for set-up purposes I suggest the PRUmsg Echo Lab 5.
So this example does not intentionally toggle any GPIO. The idea is that if you can get this lab to work, the PRU RemoteProc kernel drivers are completely functional. The final thing to do with this example is to compile the user-space C program and run it. I think the Makefile handles this, but compiling any C program for user-space is easy: gcc main.c -o pru_msg_test or something like that. Running the user-space test program does a simple exercise of the RemoteProc messaging character devices. Lab 6 toggles an LED using the PRU and uses the same character device mechanism to control the PRU. Let me know if you have any more questions. I think you have gained a lot of capability to experiment with the PRUs.
