Re: [Machinekit] Machinekit DE0_NANO why "Bus Error"

If you want to know how to access the existing GPIO using the pre-built image you have burned, that is a completely different question. It is a matter of asking the right one. I have 2 machines using DE0-NANO + 7i76 boards providing multiple axes and full GPIO from the 7i76, and one XYZ milling machine just using the DE0-NANO to provide 3 axis hardware stepping and encoder on one header and using the GPIO bank through a breakout board on another.

We use this Image: http://deb.machinekit.io/uploads/de0-nano/debian-8.5-console-armhf-2017-02-14/. Our main problem is that every time we try access to the GPIO's over a C-program we get the same Error “Bus Error“.Our question is, is there a Demon who don't let us access to the GPIO's or what kind of mistake we made. On the fpga is a .rbf file that we have generate with Quartus where we can access to the GPIO's over PIO's. We have test that with a C-Program on the from Altera provided Console Image: http://www.terasic.com/downloads/cd-rom/de0-nano-soc/linux_BSP/ -- 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.
