my own designed 7i92 board not work

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)
 

yes! it's transmitting

and I programmed FPGA , in boot the user led blinked

OK, when you ping the card, do the user LEDs count?

yes , but ping show packet loss

It sounds like its transmitting (you can verify with tcpdump)


Are you using a recent bit file?

Bitfiles before May 2018 do not mask the MAC address from the EEPROM
so an uninitialized EEPROM will result in a 0xFFFFFFFFFFFF MAC address
This may result in lost packets if the go through a switch (Bitfiles after May
2018 mask the MS byte so you get a valid MAC address even
berfore the EEPROM is initialized.)

 copied a 7i92?

... but run a fiber laser in another post... yup just for personal use

All I can say is that Peter's behavior is really respectable

I would have said amazing and extremely supportive

I received the code from mesanet and compiled and programmed (with ise)

after trying some idea , I realized the board received packet but not response to them.
i send several packet with UDP sender to board but not know the board ip.
when i send data through ip 192.168.1.255 port 27181 the led blinked (that shows the packet received)
but when send to 192.168.1.121 but Did not answer.
