Hi,
Apologies, I'm a real newbie and would really appreciate some help,
where I'm up to...
Got the latest image from here:
http://deb.machinekit.io/uploads/de0-nano/debian-9.2-console-armhf-2017-10-29/debian-9.2-console-armhf-2017-10-29-5.0gb.img.xz
I used an 8GB sandisk ultra
In linux:
sudo bmaptool copy ./debian-9.2-console-armhf-2017-10-29-5.0gb.img.xz
/dev/mmcblk0
Connected up using SerialTools on the Mac, select usbserial-XXXXXXXXX
and baud rate 115200 and hit connect.
Press any key while booting:
=> env default -a
## Resetting to default environment
=> setenv ethaddr ba:d0:4a:9c:4e:ce
=> saveenv
Saving Environment to MMC...
Writing to MMC(0)... done
=> reset
l:p is machinekit:machinekit
uname -a shows:
Linux mksocfpga 4.1.22-ltsi-rt23-ge3c1da3 #1 SMP PREEMPT RT Tue Aug 23
09:56:10 UTC 2016 armv7l GNU/Linux
cat /etc/issue
"Debian GNU/Linux 8 \n \l
Machinekit SoC/FPGA Debian Image, Altera CycloneV 2016-11-21"
ifconfig should show the MAC you set and your IP address should be
stable with DHCP
I can ssh in from my Mac Pro (install XQuartz) using "ssh -X
[email protected]"
I change directory into machinekit and run machinekit
I'm presented with the Machinekit Configuration Selector, woohoo!
Is 4.1.22-ltsi-rt23-ge3c1da3 correct for debian-9.2, isn't it supposed
to be 4.9, also /etc/issue shows 8 and the dates are all in 2016,
seems weird?
It is an upgraded Jessie image.
There is no Debian kernel for the DE0 so the kernel is one that works
What to do now with machinekit, no idea where to start, Charles made
me a G540 config:
https://github.com/machinekit/mksocfpga/commit/7e81953c7a7971daaa08c533ef1cc828dbd9fcdd
How do I get that on to this DE0?
Upgrade the socfpga-rbf package
Then check /lib/firmware/socfpga/dtbo for the config you need
Specify this one in your .ini file
So I have my G540 and a stepper, all I want to do is cable up the X
axis to verify everything works (I'm using jumper wires) so can
somebody please give me a newbie guide to what I do next, my thoughts:
DE0 to G540 DB25, on the G540 it seem I only need to connect pins 2
(X-AXIS STEP) & 3 (X-AXIS DIRECTION), which pins will I connect that
to on the DE0 once I import the Charles G540 config, direct DE0 pin to
G540 pin connections as I don't have an assembled DE0-Nano_DB25 (I got
three from osh park but I'm waiting for the parts to come from
digi-key and I will have to do a bunch of practice before I even
attempt to solder 0603)?
DB9 for X AXIS I need to connect the four wires from the stepper to
pins 6, 7, 8 & 9, 6 & 7 are the A coil, 8 & 9 the B coil, how to work
out the order as the stepper wires (black/green are one coil and
red/blue are another according to a piece of paper that came with the
stepper)?
Plenty of sources on the net for this
Once I have the G540 config and have wired the above simple test what
do I do from the "Machinekit Configuration Selector" page to just test
one stepper, is that possible, if so, how?
I would suggest that you modify the configs/hm2-soc-stepper/5i25-socfpga.ini
and hal sim for now
Don't worry about attaching steppers until you have a DB25, because the
pinout on the headers is different and you will get in a right mess quite
easily
Sorry to be a pain but this would really be a lot of help.
Thanks.

Hi,
Thanks for all the help.
So I have the DE0-Nano-SoC, G540 and steppers are there instructions on
how
to install machinekit on the SoC and mesa on the FPGA?
I should be able to wire it all up OK, I'm basically going to start by
getting one stepper moving as instructed, I'm calling this phase 1.
So it will be DE0-Nano-SoC connected to G540 connected to a stepper.
I will just install Cetus on Android.
Am I taking the path of least resistance?
Any documents, tips or tricks that will help me?
My computer skills are great so as long as I have instructions I will be
fine with that.
I know very little about CAD/CAM or emc2/linuxcnc/machinekit.
Thanks again.
Richard
