watchdog and network connection problems

hello everyone, im having some issues after i installed debian and linuxcnc according to this post docs.google.com/document/d/1jeV_4VKzVmOI...m1x7oiw8VcLFdiY/edit. everything worked great until i had an idea to install another realtec network card. it worked for about a day and then the watchdog bite came on but it would still run. i shut it down and the next day, nothing worked. the watchdog would come on as soon as i booted the machine and wouldnt even go off when i reset the 7i96s. next, i removed the additional ethernet card but it still wouldnt work so i reinstalled everything according the preceding post. now, no matter how i configure it (through /ect/network/interfaces or through the gui) the network shows up somestimes but most of the time it doesnt show up in the list and i followed that post to the letter. ocationally i can ping the board and the ping times are >200 usec. im at a loss at this point and had to walk away from it. im wondering if anyone has any ideas. i have nothing but issues with this setup and it shouldnt be so hard to setup. i shouldnt have this many issues. what am i missing?

Shows that the link is down which means that you have no connection with the 7I96S

Also its not suggested to use a /8 netmask, a /24 should be used instead

Not sure why adding a additional network card would cause an issue unless
its somehow affected the driver (didn't you inslal the DKMS driver for the
RealTek Ethernet previously?)

Also not sure what you mean by:

"the watchdog would come on as soon as i booted the machine and wouldnt even go off when i reset the 7i96s"

 

i did install the dkms drivers. what i mean by watchdog; the red light on the mesa 7i96s will illuminate as soon as i turn the pc on. when i go into pncconf and try to test an axis, i get an error that the halcmd is not running and i should invoke halcmd start to resolve it but that has no effect. also, i am unable to flash new firmware to this board. i have installed mesact a number of times and the firmware section is greyed out every time. no matter what i do. and when i run mesaflash --addr 10.10.10.10 --device=ETHER --readhmid, it does nothing. no output. i have to hit ctl+c to get my terminal back. i am at a lose here. i don't know why installing a new ethernet board would give me these issues either. maybe someone knows of a different setup that wouldn't be so complicated to setup. heres the error report i amd getting when i run lcnc; Error report created by /usr/lib/tcltk/linuxcnc/show_errors.tcl:

thanks for all the help. if anyone knows of a less complicated setup, i would open to any and all suggestions.

i even used a different Ethernet cable to make sure it wasn't the cable and no improvement. there are only lights on the rj45 connector on the mesa board after i reboot the board. and i can get a ping time from it for a couple seconds then it goes to host unreachable and it drops most of the packets. i haven't installed ANY wizards lately. or tried to flash the firmware. if i can't read the board, i don't think flashing will do much good. at what point do we start to question the hardware? is there a way to test the board to make sure it is operation properly?

okay, i just reinstalled Debian and setup the network interface and i am getting ping responses. and no red light. yet. i am going to go through the process of installing lcnc

unable to run pncconf. it freezes and says its not responding and asks if i want to exit the program. and the red light on the board is on and i am unable to ping the 7i96s. host unreachable.

heres what i get when i ping the 7i96s; ping 10.10.10.10

and the red light is on on the mesa 7i96s.

A red light on 7I96S at power up likely means you have a marginal
5V power issue or corrupted flash memory.

 

i've tried a couple different power supplies. how do reflash the 7i96s?
