Re: [Machinekit] Will DE0-Nano image work on a DE10-Nano board?

2017-07-31 Thread Condit Alan 
Charles,

The DE10 won’t boot from the DE0-Nano-SOC MachineKit image. I need to get an 
adapter for USB female to Micro male (or USB OTG) so I can plug in my powered 
USB hub or at the very least a USB keyboard with built in touch pad.  

I guess I will try to set up so I can compile on the DE10-nano. The only linux 
box I have in the house is an i386 and the current cross compiler only runs 
64bit mode.

I may be able to use the 386 box to run linuxcnc in the shop and bring the 
D525MW inside to set up a cross compile environment but the D525MW only has a 
32gb SSD at the moment.
