You have jtag and CCS supports direct register examinations Set a breakpoint in main get out the TRM for bit settings of mux and config registers Let us know what you expect them to be and what they are and what OS is running on ARM

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 : JTAG and a source level debugger -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
