Hi, I'm a beginner in BeagleBoard-X15. I'm using the beagleboard PRU and i want to debug the PRU gpio which using the CCS and the JTAG. I learned that PRU can directly control GPIO through __R30. I found out from the schematic diagram that the pin GPIO3_7 of P19 on Beagleboard-X15 is PR1_PRU0_GPO0. I want to output Toggle level directly through __R30 and then observe it through oscilloscope but it is doesn't work.I don't know what to do next. Here is my code : [image: PRU.png]
