Mesa 7i92M Support

linuxcnc.org/docs/2.7/html/motion/tweaki...setup_and_or_dirhold

Having a bit of trouble running a Bananna Pi M2 with kernel 4.4.1-rt6-sunxi which is a preempt_rt kernel. Have set /etc/network/interfaces to:
auto eth0
iface eth0 inet static
address 192.168.1.1
hardware-irq-coalesce-rx-usecs 0
able to connect with network manager to ip 192.168.1.121 according to network manager.
But when running in Terminal:
tim@bananapim2:~/mesaflash-master$ ./mesaflash --device 7i92 --addr 192.168.1.121 --readhmid
No 7I92 board found
I have installed
github.com/micges/mesaflash
because mesaflash is not avialable from Synaptic when doing search for Hostmot2 I installed LCNC from buildbot.
Could use some help do not know what to do next

Tim

Can you ping the 7I92 card? if not you need to find out why first.

Is the card jumpered for 192.168.1.121 ? and did you power cycle the card after moving jumpers?

Do you have a local network (Say with WIFI or another Ethernet connection) that overlaps 192.168.121?

Dis-connected etho cable from router then connected cable to 7i92m ran:
tim@bananapim2:~/mesaflash-master$ ./mesaflash --device 7i92 --addr 192.168.1.121 --readhmid

So I guess I am good correct?

I will have more questions later going to bed thanks PCW

Yes, that shows the 7I92 is connected and working
If you have a overlapping IP address range on another connection
(you did) the packets to 192.168.1.121 are going to be routed out that
connection instead of to the 7I92.
This is why its suggested to use the 10.10.10.10 address instead of the default
192.168.1.121. The default address is handy for setup (on a shared network)
but not good for a dedicated connection because of the likelyhood of overlap
with standard DHCP pools

BTW you dont need the addr=192.168.1.121 (its the default if no address is specified)

Hello. This is my first experience with the use of EMC2. After the spoiled details on MACH3, I bought Mesa 7i92. The problem is that drivers Leadshine AM882H goes into error if there is no software Enable. When the power is turned on, it indicates a phase error, or a current error. With the software Enable, everything works well. But I can not assign to a free pin - I do not know how to register. I would also like to connect a touch probe and an external e-stop, but it's already secondary. Without software enable I can not work. I tried to write like this:
But still on all free gpio + 5v.
Sorry for my english. Thank you in advance for your cooperation.

Physically, it is connected to an oscilloscope. I look at the oscilloscope as the signal changes. At the moment there is always + 5V, as on other free iO. In the configuration, I didn't write anything else - I don't know how.
