Hi,
I am practicing PRU_ADC_onChip example from TI software support package.
I came across this problem.
root@beaglebone:/var/lib/cloud9/pru-software-support-package-5.7.0/examples/am335x/PRU_ADC_onChip# ./pru_adc_userspace -c 5
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
So I ran /opt/scripts/tools/version.sh and it is attached below. It seems firmware is not loaded properly? Can anyone explain why this happens?
BTW, I ran the same code on Beaglebone Black, and it runs smoothly.
Thanks in advance.
Regards,
Cheng
