Mesa 7i76e No Board Found

Hi All,

I have been a long time reader and first time poster as i have recently decided to dive into the world of linux cnc after years of reading.

In trying to set up my PnCConf i was unable to test my motors and after hours of re-wiring and troubleshooting I think I may have found the problem (probably where most people would look first).



First part is the "ip a"

however I am unable to ping or flash the board

I have the W2 down and W3 Up for the 10.10.10.10 IP address.

When I go to etc/network and try to edit the interface it gives me an error saying "cant open file to write"




This may be because I am going through etc/network instead of /etc/network, however I dont know how to access this file location. Do I go through File System- File manager?



Any help is greatly appeciated becasue I have been pulling my hair out for days trying to get this to work

Your network is not setup properly
You can ether edit the /etc/interfaces file as suggested in the hm2_eth man page,

(man hm2_eth)

Note that to edit the interfaces file you must be the root user so assuming you have the
mousepad editor, you would:

sudo mousepad /etc/network/interfaces

or setup a static IP address for the host pc using the network manager, I think its launched with a icon on the top left of the screen

Thank you very much for your fast response!




does this mean I am not a root user?

Yeah, I'm not sure why you are in this situation, perhaps an error during installation
Its fixable ( google "not in sudoers file" ) but a bit fussy to fix

What LinuxCNC image are you using?

I am using the master branch of wheezy

For a 7I76E that needs the uspace version of LinuxCNC
I would start with the Stretch test ISO here:

www.linuxcnc.org/testing-stretch-rtpreempt/

( probably linuxcnc-stretch-uspace-amd64-r13.iso which is a 64 bit installation,
no need for 32 bit versions unless you have an ancient PC) )

Legend! Thank you. I was able to add myself as a root user to change the network address. I will test this with the board to see if it works now.

It worked!

I can now get an “ip a”

I can “ping 10.10.10.10”

And I can do “mesaflash - -device 7i76e - -addr 10.10.10.10 - -readhmi”

However when I go to test/tune motors in pncconf nothing happens. any ideas?

Also attached is what “uname -a” brings up, does this suggest anything? Should I install the uspace even though I got a mesaflash by just changing the address?


EDIT: Also noticed that is says3.4.9-rtai however this is followed by #1 SMP PREEMPT

hence I am not sure whether its RTAI or RTPREEMPT however I am sure that I downloaded the preempt.
