EEPROM warning

GNU Radio

Hello,

Any know what is the cause of the following EEPROM warning? I would
appreciate any suggestion on how to resolve this problem.

[root@home usr]# usrp_siggen.py -f1

Warning: Treating daughterboard with invalid EEPROM contents as if it
were a “Basic Tx.”
Warning: This is almost certainly wrong… Use appropriate
burn-*-eeprom utility.

Using TX d’board A: Flex 900 Tx MIMO B
Failed to set RF frequency

have you tried using the appropriate burn-*-eeprom utility?

It should be something like “gnuradio/usrp/host/apps/burn-db-eeprom -f
-A -t (your card type)”. You can find your card type and the options
in the code here:
http://www.gnuradio.org/trac/browser/gnuradio/trunk/usrp/host/apps/burn-db-eeprom?rev=6130
(burn-db-eeprom -h might work, mine fails)

Ack, that’s a very old link, drop the ‘?rev=6130’ from the end

Hi,
I have one USRP board and 2 Flex900 boards. The Flex900 board has
both RX2 and TX/RX. I installed and screwed both Flex900 boards on
USRP motherboard and make sure all the holds are matched.

On the B side, I have Flex900 card.

What do you think could be the problem?

Thanks,
Woody

Hi Jason,

Thanks for your help.

Does it mean I should burn the EEPROM myself?

Where can I get the instruction on how to build the EEPROM?

Since I don’t see any EEPROM burning instruction from the gnuradio
installation doc. I just want to confirm the exact steps on that so I
would accidentally destroyed my EEPROM.

Thanks,
Woody

What do you have on the B side?

Hi,

I burn the EEPROM but I am still getting some problems:

[root@fodora apps]# ./burn-db-eeprom -A -t rfx900_mimo_b --force
TX_A: OK
RX_A: OK
[root@fodora apps]# usrp_siggen.py --const -f 10M -i 128
Using TX d’board A: Flex 900 Tx MIMO B
Failed to set RF frequency

I am still getting the same error.

I would appreciate any help in getting my USRP to work.

Thanks,
Woody

Hi,
I got it now. I was not using the correct frequency range. I get it
worked out using -f 950M

Thanks,
Woody
