Hi all, I am trying to run the PRU example under /var/lib/cloud9/BeagleBone/AI/pru/blinkExternalLED.pru1_1.c and it is not working. It compiles with the Makefile and after placing the firmware under pru1_1 core (cp blinkExternalLED.pru1_1.out /lib/firmware/am57xx-pru1_1-fw), the pru start correctly (according to dmesg -Hw) with (echo 'start' > /sys/class/remoteproc/remoteproc5/state). However, I do not see any LED blink on P9_25 of my beaglebone AI. I have checked:
- the GPIO6_17 DATAOUT register is changing every 0.5s according to devmem2 (sudo devmem2 0x4805D13C) but the LED is still not blinking. - pinmuxing is such that /opt/scripts/device/bone/show-pins.pl gives "P9.25 165 D18 e fast down gpio6_17" so it's seem to be configured correctly. Can anyone help me? Best Pierrick -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
