7i97t will ping, not recognized by mesaflash

I just spent the day finding possible solutions in the forum and attempting them. I have reinstalled the linuxcnc os several times to ensure previous attempts to fix the problem didn't interfere with other attempts.

The card is new. Only 5v power is being supplied. The PC is a fresh install of linuxcnc 2.9.2. The PC is only connected to the mesa 7i97t by ethernet. The PC's ipv4 is set manualy to 10.10.10.11
Mesaflash 3.4.9 is being used.

When pinging 10.10.10.10 in the terminal it works. I can even watch the led's on the mesa act like a filling progress bar.
When attempting "mesaflash --device 7i97t --addr 10.10.10.10 --verify FPGAFILE.BIN" the terminal returns "unsupported ethernet device 7I97T at 10.10.10.10 No 7I97T board found"
When attempting "mesaflash --device 7I97T --readhmid" it returns "lbp16_access.send_packet: Network is unreachable Aborted"

I have attempted to use the 192.168.1.121 header on the board with even less luck. It is unable to be pinged.
Preferably I would like to get the card working on the 10.10.10.10 address. 
Do I need to attempt to use the fallback? No red leds are lit.

Any suggestions are appreciated.

I apologize, I should have added the minimum required
mesaflash version for the 7I97T (3.5.3) in  the 7I97T manual.
 (the 7I97T is quite recent)
 

Thank you both for your quick responses.

To answer Tommylight, I wasn't attempting to flash it. I wanted to use mesaflash to read its current info, and verify the board is working. The manual I was reading stated mesaflash 3.4.5 or later was required. When I was unable to communicate with or recognize the board using mesaflash 3.4.9, I thought I had a dud. Now, thanks to PCW I know that I need 3.5.3 or newer. At this time github has 3.4.9 listed as master. Since ping works and I do not need to flash the card I will continue on with my fears of a dud alleviated.

Current mesaflash version at:

github.com/LinuxCNC/mesaflash

is 3.5.7
