I just tested your update script on the BeagleBone with a freshly compiled UB3+JA4 branch. It seems to have worked pretty well, but after the initial conversion, LinuxCNC refused to start. Both the AXIS_X and AXIS_Y had the value "None" for both the MIN_LIMIT and the MAX_LIMIT. These values are in the original ini file, but commented out. I'm not sure if it's OK to launch w/o limits in place, but it seemed to work previously...and by "work" I mean I was able to launch LinuxCNC and jog the three axis motors manually which is all I've ever done to date with the K9 board. I manually put in some reasonable limits, and all is well (LinuxCNC launches again, and I can move motors). It seems to me that either the "limit doesn't exist" condition needs to be handled properly (if it's really legal), or it might be good to do a sanity check and make sure all required data (limits and anything else needed) is actually present prior to conversion. The configuration I am starting with is the GPIO-Driven.ini file, which can be found (along with it's corresponding HAL files and other setup requirements) here: https://github.com/mhaberler/linuxcnc/tree/unified-build-candidate-3-joints_axes4/configs/ARM/BeagleBone/K9/Standard-Configs ...and thanks for the update script, btw! :) -- Charles Steinkuehler [email protected]
