I created this user from the original debian image. I followed the steps located in this tutorial. https://machinekoder.com/machinekit-debian-stretch-beaglebone-black/ looking at the udev rules it appears that they apply to users in the "gpio" group. My machinekit user is not in the "gpio" group. I tried to add this user to the "gpio" group using sudo su usermod -aG gpio machinekit exit When i list groups the machinekit user is still not in the "gpio" group. I read the group change is not immediately changed so a reboot is required. logout and login would also work. After reboot machinekit is in the "gpio" group After this machinekit runs with the CRAMPS.ini configuration. I commented out the eMMC pins that were set up for "servo" use. Robert, thanks for the nudge in the right direction. ; ) Jim -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.

[Machinekit] Machinekit issue with config-pin on BBB
I am trying out Machinekit on the BBB. I am wanting to keep the HDMI output on the board. I have the uEnv enable_uboot_cape_universal = 1 I do not have an actual cape on the BBB at this time. I am trying to run the CRAMPS sample configuration. I am getting the following error. sudo: no askpass program specified, try setting SUDO_ASKPASS Cannot write gpio direction file: /sys/class/gpio/gpio66/direction. CRAMPS.hal:12: program 'config-pin' failed, returned 1 In the CRAMPS.bbio file the first pin it tries to configure is P8_07 which equates to gpio66. If I comment out that line it gives the error for the next pin gpio67 or P8_08. These pins should not be conflicting with the HDMI cape. What is the issue with this set of errors. I do see something in the CRAMPS.hal file that concerns me after this. it says the following. loadrt hal_bb_gpio output_pins=816,822,823,824,825,826,914,923,925 input_pins=807,808,809,810,817,911,913 I don't understand why it is trying to set pins 822,823,824,825 as gpio. What are the "servo" signals used for that are connected to these pins. I don't see a purpose. Then you would not have to disable the eMMC. Mainly looking for help on the SUDO_ASKPASS issue and not being able to write to the gpio pins using config-pin.
