Hi
i used 7i92 schematic and designed a board.
all part is same with 7i92 schematic but board does not have ip address
in 7i92 user manual said default ip address is 192.168.1.121
were this ip stored and how change it.

also how i can set eeprom ip address for first time (board not detected with mesaflash!)

Not wanting to discourage, but you are asking us for advice with respect to a board you designed and built. Why would any of us have more knowledge of that than you? And why would Mesa inform you of how they do this, when you are making a copy of their product? Good luck, but you are probably on your own on this one.

The 192.168.1.121 address is hardwired in the 7i92 firmware so does not need to be set. Once you have
communication, you can set the EEPROM address with mesaflash:

mesaflash --device ethernet --set --addr 10.10.10.12

I must say that Peter has faith in his support and product to assist someone who built his own version of what he sells to help them. 

Kuddos to you for helping this individual out.

Yeah, Peter has a habit of helping everyone !
And this is not the first time he is helping someone trying to copy his equipment, plenty of those in this forum.
For that he deserves the utmost respect.

Thank you very much for your answer.
I must say that we do not want to copy your equipment. We can not easily supplies your equipment in our country. We use them for our product, not for public sale. Anyway, thank you for your help .

I connect my board to system and set network interface ip adderss to "192.168.1.100" and I tried to use the command you said  , but mesaflash not found the 7i92 card , i used several version of mesa flash also use my own compiled mesaflash to run this command . Are you using a specific mesaflash version?

Can you ping the card? (ping 192.168.1.121)

Mesaflash must use the --device ethernet command
and the 192.168.1.121 address until you set the card
name and EEPROM IP address address in the
cards EEPROM

I am using the standard mesaflash (3.4.0)

No, I can't ping card !
I think the solution is to program the IP address on the eeprom network chip!
Do you have an opinion on this ?! Possible or how?!

No, the card should respond to pings regardless of what's in the EEPROM,
because the 192.168.1.121 address is in the FPGA configuration, not the EEPROM.

I suspect a hardware issue. If you set the IP address jumpers to the
bootp setting (Up/Down on a 7I92) does the card transmit once per second?
(this should be visible on the link lights)

Actually I should step back a bit, before you run mesaflash,
have you programmed the FPGA via JTAG? (this is necessary to bootstrap the card)
