[srsran-users] Variation in B205mini i and SRSRAN

[info@ep90]

Dear all, I am very new to this forum so please forgive any etiquette errors.

We have been building a POC device that utilises an Ettus B205 mini i and SRS RAN. We recently purchased another B205mini i and it successfully pulled down the latest updates - or so we think. 

Attached is an image of old and new with the result of uhd_usrp_probe. Newer on the left (SN 34170C7) and older on the right. Revision, FW and FPGA image are all the same. 

When we run SRSRAN on the OLDer one we get a test network as expected. 
When we run the newer one with exactly the same SRSRAN config (on the same machine), it appears to work but does not generate a test network. Any ideas?????

For reference we have confirmed that a GNU radio simple TX / RX test works as expected on both old and new. An independent device confirms that there is a signal being passed from TX to RX on both. 

This has left us very confused with no clue where to go now, has anyone seen this issue before and have any ideas as to what is wrong?

Thank you all in advance for taking the time to read this.
