7i92 firmware issue

Building 7i92 firmware for a custom board. I've had to play around with

Turn on board everything seems ok, user leds count packets
IP set to 192.168.1.121
Responds to pings
When jumpered for bootp an ip address is received and I can ping it.

This has me stumped 7i92 mac is ff:ff:ff:ff:ff:ff

$ mesaflash --device 7i92 --addr 192.168.1.121 --verbose
Unsupported ethernet device ��������������������z at 192.168.1.121
No 7I92 board found

��������������������z bit will change on each mesaflash run

I'm guessing the data in the last packet isn't right.

 

Sounds like the MAC/cardname/ipaddress/netmask EEPROM has not been programmed

Ok much appreciated.
It's 2:45am I best be getting some sleep.
Guess I'll swap the eeprom.

I'm not so much suggesting that the EEPROM is bad, but rather
that the EEPROM is empty. (never been programmed)

Oh the 93c46 has to be programmed separately ?

I thought the firmware did that

I understand now, silly me.
Ok found I had to use setname & found the Linux version here
www.forum.linuxcnc.org/27-driver-boards/...board?start=10#65737

and I can communicate.

Thanks again

Here's a more complete set of utilities:

( note that you should not use Mesa's MAC in the addresses in the scripts )

Wow thanks Pete, was just thinking about how to do this. I really think I owe you a few beers.

Another question, if I may.
[/code]./setmac 00601B168$1/[code]

What's the format for the MAC ?

12 hex characters (this is from an initialization script so the
last three characters (the $1) are supplied on the command line

that is:

./setmac 00123456789A

etc

Note that "00601B" is Mesas range

./newmac: line 8: ./setmac: Text file busy
Reseting Ethernet CPU
waiting for reset
./newmac: line 14: ./setmac: Text file busy


Is that a worry ? Or is that due to network latency ?
Board is behind a switch and I'm working on a laptop connect via wifi, I can ping and readhmid with mesa flash ok

I used ./setmac 00123456789A in the script

Dumb me I should have sourced the file. All is good.
