Hi all, I am new learner of Beaglebone Black and I was trying to follow the examples of Programmable Real-time Unit software support package from TI. I think there was a tutorial website previously but now it's obsolete. I wonder if anybody knows where those materials is available? The reason I asked is I am not able to successfully run any examples except PRU_gpioToggle. In particular I am interested in RPMsg transfer between ARM and PRU. For example, PRU_ADC_onChip <https://git.ti.com/cgit/pru-software-support-package/pru-software-support-package/tree/examples/am335x/PRU_ADC_onChip?h=master>, after I built the firmware and userspace code, and run ./pru_adc_userspace -c 5. It just shows error messages.
Reading voltage at ADC Channel: 5 /dev/rpmsg_pru30 could not be opened. Trying to initialize PRU using sysfs interface. ERROR: Could not open /dev/rpmsg_pru30 I think it should be just some minor issues like driver missing and such. But I don't know where to start debugging. It would be nice that if anybody knows where the tutorial is. I feel like I'm just trying in the dark. Thanks.
