I have a Beaglebone Black and installed the stretch image from https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#BBW.2FBBB_.28All_Revs.29_Machinekit_2
I figured I'll use halrun to confirm the basic setup and the major IO pin assignments but run into a basic problem - which is entirely rooted in my ignorance of how this is supposed to work. I am looking at the CRAMPS configuration for inspiration and guidance but obviously I'm missing something basic. I'm using something like this for testing an output pin: newthread servo nofp 1000000000 loadrt hal_bb_gpio output_pins=912 addf bb_gpio.write servo start setp bb_gpio.p9.out-12 1 setp bb_gpio.p9.out-12 0 which works fine - until I start using different pins. CRAMPS uses pins 807,808,809 and the moment I try to use one of them I get an error message about some dangling ROUTER. Checking /var/log/linuxcnc.log I find the following message: May 8 00:25:31 machinekit rtapi:0: 1:rtapi_app:1053:user hal_bb_gpio: ERROR: GPIO Port 2 is not enabled in device tree This is the output from /opt/scripts/tools/version.sh: markus@machinekit:~$ sudo /opt/scripts/tools/version.sh git:/opt/scripts/:[9df8deb6b2ae7570c9102ab58f795d3bed592194] eeprom:[A335BNLT00C03818BBBK09B3] model:[TI_AM335x_BeagleBone_Black] dogtag:[Machinekit Debian Image 2019-04-14] bootloader:[microSD-(push-button)]:[/dev/mmcblk0]:[U-Boot 2019.01-00002-g6de8c74429]:[location: dd MBR] bootloader:[eMMC-(default)]:[/dev/mmcblk1]:[U-Boot 2016.01-00001-g4eb802e]:[location: dd MBR] kernel:[4.19.31-bone-rt-r31] uboot_overlay_options:[enable_uboot_overlays=1] uboot_overlay_options:[disable_uboot_overlay_video=1] uboot_overlay_options:[disable_uboot_overlay_audio=1] uboot_overlay_options:[disable_uboot_overlay_wireless=1] uboot_overlay_options:[uboot_overlay_pru=/lib/firmware/AM335X-PRU-UIO-00A0.dtbo] uboot_overlay_options:[enable_uboot_cape_universal=1] pkg check: to individually upgrade run: [sudo apt install --only-upgrade <pkg>] pkg:[bb-cape-overlays]:[4.4.20190429.0-0rcnee0~stretch+20190429] pkg:[bb-wl18xx-firmware]:[1.20190227.1-0rcnee0~stretch+20190227] pkg:[kmod]:[23-2rcnee1~stretch+20171005] WARNING:pkg:[librobotcontrol]:[NOT_INSTALLED] pkg:[firmware-ti-connectivity]:[20180825+dfsg-1rcnee1~stretch+20181217] groups:[machinekit : machinekit adm kmem dialout cdrom floppy audio dip video plugdev users systemd-journal i2c bluetooth netdev gpio pwm eqep admin spi tisdk weston-launch xenomai cloud9ide] cmdline:[console=ttyO0,115200n8 root=/dev/mmcblk0p1 ro rootfstype=ext4 rootwait coherent_pool=1M net.ifnames=0 quiet cape_universal=enable] dmesg | grep remote [ 0.870377] remoteproc remoteproc0: wkup_m3 is available [ 1.219779] remoteproc remoteproc0: powering up wkup_m3 [ 1.219802] remoteproc remoteproc0: Booting fw image am335x-pm-firmware.elf, size 217168 [ 1.221865] remoteproc remoteproc0: remote processor wkup_m3 is now up dmesg | grep pru dmesg | grep pinctrl-single [ 0.690466] pinctrl-single 44e10800.pinmux: 142 pins, size 568 dmesg | grep gpio-of-helper lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub END 'been banging my head against this for a while and can't figure it out.
