I haven't worked with the Green. All of the cape and I/O configuration is handled before machinekit really starts by launching the "setup.sh" script at the top of the HAL file. You can edit this script to work with the new kernel and/or just comment it from the HAL file and setup things manually. To run the example CRAMPS setup, you need the uio PRU driver loaded, the ADC driver loaded, and the I/O pins setup to the appropriate mode (typically GPIO input or output). Potential problems are with the PRU driver (some kernels have the uio driver and some have the remoteproc version) and maybe the ADC (the sysfs files for the ADC might have moved around in newer kernels, I'm not sure). The I/O setup should be straight-forward, as the universal overlay I use for the CRAMPS board is now included in all the BeagleBone kernels. You may need to tweak something to get the overlay loaded, but the same config-pin commands should work to setup the I/O. -- Charles Steinkuehler [email protected] -- 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.
