Possible WBX Board Failure

GNU Radio
1

Hello,

When using a particular WBX daughtercard I get this message from my
script:

Current recv sock buff size: 60000000 bytes
mboard0 MIMO master

Warning:
Unknown transceiver board ID combination…
RX dboard ID: WBX (0x0053)
TX dboard ID: Unknown (0xffff)
Traceback (most recent call last):

in virtual void unknown_rx::rx_set(const wax::obj&, const wax::obj&)
at /opt/uhd/host/lib/usrp/dboard/db_unknown.cpp:176

The first two lines are normal… but the rest is not. I’ve tried to
use
different machines, different USRP2s, different SD cards (all burned
with
the same firmware though) and I always get this message. The only
reason
why I can think for this happening is a broken WBX board… Can anyone
think
of any other reason this?

For reference, the WBX serial number is 741, in case there is something
wrong with that batch of WBXs.

Thanks for any help,
Devin

This is usually a sign that the board is not mounted correctly. Re-mount
the WBX and try again.

So I checked all the pins in this daughtercard and they all look fine.
Could it be anything else?

Thanks any help,
Devin

Also, here is the output of uhd_usrp_probe

He says that he tried it on multiple USRP motherboards, so it’s unlikely
to be, per se, a mounting issue. But I’d
check for a bent pin on the daughtercard connector.

The wrong ID is being read from the eeprom. Usually, this is an issue
with mounting. On the off chance that the eeprom got
corrupted/blanked/shocked, you can manually burn an ID in with the
following tool:

cd /share/uhd/utils
./usrp_burn_db_eeprom --id=0x0052 --unit=TX

See if that helps,

Looks like that didn’t work for me…

The output of uhd_usrp_probe is the same afterwards as well. Also,
screwing
in all the screws didn’t help either :frowning:

Is there anything else I can try, or the eeprom on this board fried?

Again, thanks for any help,
Devin

Hi Devin,

You might have tried this already but here it goes : when i first got my
WBX board, I had a similar problem - TX works but not RX. The
daughterboard seemed to be securely attached (i had used only 2 screws).
When i put in all 4 screws, then both TX and RX began working.

Best regards
-Vijay
