I attached the .ini file I am loading, where I added the HALUI = halui statement in [HAL] section and my custom .hal file HALFILE = remote_sps.hal, which is also attached. Furthermore, I attached the .bbio file. I changed the values for the pins 43, 44, 45, 46 of port 8. OK, that should help Whilst we are waiting for the BBB gurus, I notice that parallel-cape2.bbio still includes the hdmi cape overlay you say is disabled I assume that cape uses the pin you chose, are you actually sure it is disabled? Try commenting out the overlay line? In file 'base_bbb.hal' I added 846 to the input_pins. Have you tried NOT exporting the pin and writing to it via fd  calls in /sys/class/gpio ? The driver undoubtedly uses memory mapping to address the pin, but don't know how exporting it and writing to it using fd interface as the system is booted might affect that The other suggestion is to set DEBUG = to a high number ( at least 5) run and then look at /var/log/linuxcnc.log The hal_bb_gpio driver has numerous debug error prints  - you may catch something there regards The startup script (/etc/rc.local) looks like this (it already contains some more pins I want to use in future) echo 70 > /sys/class/gpio/export echo 71 > /sys/class/gpio/export echo 72 > /sys/class/gpio/export echo 73 > /sys/class/gpio/export echo in > /sys/class/gpio/gpio70/direction echo in > /sys/class/gpio/gpio71/direction echo high > /sys/class/gpio/gpio72/direction echo high > /sys/class/gpio/gpio73/direction echo 0 > /sys/class/gpio/gpio72/value echo 0 > /sys/class/gpio/gpio73/value I also attached the uEnv.txt -- 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.
