MESA 7i97T, unable to ping board, strange lamp behavior

Hi all.

My card arrived today :-D

This took me some time to figure out what was going on and some time to figure out (well, 99.99% sure) that its not the controlling PC, but is the board itself.

1. I have setup as per tutorial by Tommylight at www.forum.linuxcnc.org/27-driver-boards/...ethernet-mesa-boards (Thanks!)
2. I have confirmed that I can connect my PC by ethernet cable to my homes network and ping other devices
3. i have tried using both the default jumper settings of DOWN DOWN to select 192.168.1.121 as well as DOWN UP to select 10.10.10.10 addresses, all fail to return a ping.
4. The board flashes as per this video when it is connected to my home network or direct to my control PC
   1. without connection to another device or network, only the yellow power lamp is illuminated.
      
      
      
      
      
      I hope someone can give me some tips I have not tried mesaflash or anything like that yet- but it seems pointless if I cannot even get it to ping back to me.
      
      I hope someone can fire some wisdom my way :-D 

PS, thats my dog snoring in the background, not me breathing, haha

Hi Tommy.

frustrating that this could be such a simple error, but i think you are right.

I'm using a PC power supply to get it going on the bench - this should supply more than enough but looks like when i plug in the ethernet cable, voltage starts fluctuating *awkward*

ip a returns this.

Looks like an issue with the 5V power (resetting over and over)
I would use a decent 2A or so 5V power source and make sure the
power wires are not too thin or long.

Thanks guys. Had multiple issues. Using a laboratory power supply the card boots up fine and after much stuffing around have got the raspberry pi able to ping it.

Thanks again to the great community and support here.
