Thank you, Rich. The Numato Mimas v2 is just now working for me. It
explains the "connected to /dev/ttyS0" message from microcom, which I
thought was odd, but I assumed /dev/ttyACM0 aliased /dev/ttyS0
somehow. Solution was that this line from the http://j-core.org
stty -F /dev/ttyACM0 -crtscts && ~/busybox-x86_64 microcom -s 115200 /dev/ttyACM0
Which I simplified to using microcom from Ubuntu 14.04:
stty -F /dev/ttyACM0 -crtscts && microcom -s 115200 /dev/ttyACM0
Needed a -p flag added before the port:
stty -F /dev/ttyACM0 -crtscts && microcom -s 115200 -p /dev/ttyACM0
I'll demo it at hackerspace this Tuesday. Previously I demo'ed an
HX8K running a few things I'd written with yosys and a Forth on a soft
CPU. They already know I want an FPGA Linux laptop-shaped-object.
Next week I'll download the 30 GB of Xilinx FPGA tools.
http://j-core.org contains the typo "Xlinux" for "Xilinx".
Am I running "Xilinux"?
I want to try to get VGA and a slow-speed ethernet going on the Numato
as a way to learn about FPGA.
I hope those Turtles are offered for sale soon, I'd rather have my
hackerspace buddies buy the preferred platform.
