[USRP-users] UBX initialization on X310

I see what you are saying related to components F3 and F26, "wicked" close to the standoffs, but no luck, same issue after removing each one individually and re-testing...

Here's a stab-in-the-dark.... At one time, the UBX had an issue with two (of 8) of the stand-offs interfering with a component on the bottom of the UBX board. In my case, the symptom was getting REF Locked errors. This symptom is not the same as you are seeing, but then again, I wasn't using uhd_usrp_probe. I noticed that the error message seems to occur in a set_frequency function so it is conceivable that this is the issue. 

Here is the link to the discussion I am referring to...

So I swapped in a wbx in each slot one at a time and things worked for the wbx... 

I them placed 1 wbx and 1 ubx in the x310 and ran uhd_usrp_probe, output attached. 

It knows that slot A is a UBX-160 v1, but doesnt seem to recognize the frontend component (Name: Unknown (0xffff_ - 0 )) as can be seen in the attached... 

I know back in the day, some of the cards came without a serial number burned, so the cal utilities wouldnt work and they had to be burned manually... 

Perhaps something similar here for the frontend name? 

The wbx frontend names are proper... 

Slot A is UBX, Slot B is WBX...

Hi, 

The UBX drivers were added in 3.8.2, so you should be ok there. Can you double check that the UBX daughterboards are seated correctly? If you switch back to a WBX board, does it still work ok? 

Also, could you provide the other info that is printed out after "The daughterboard manager encountered a recoverable error in init." There may be some useful debug information there.

So I swapped out my 2 WBX daughtercards for 2 UBX cards (sweetness). 

uhd_find_devices is ok, uhd_usrp_probe returns errors on both cards after about 20 seconds of trying to initialize to the tune of: 

The daughterboard manager encountered a recoverable error in init. 
... 

Some other info is printed out afterwards... 

Do I need a newer version of UHD to support UBX? 

Is there some other change I need to make to support UBX on X310? 

Thanks,
