Hello Carry,

a fix for this issue is still in the pipeline. As per your question on how
to go to an older version, please try setting up your device by performing
a cross-compilation by source, as explained in
https://kb.ettus.com/Software_Development_on_the_E3xx_USRP_-_Building_RFNoC_UHD_/_GNU_Radio_/_gr-ettus_from_Source


While following this procedure, please try building with these commits:

For gr-ettus: https://github.com/EttusResearch/gr-ettus/commit/
30302780a44f3f0b146e9b81f88e70c9d983f559

For UHD: https://github.com/EttusResearch/uhd/commit/
12a34d6ef6b9666e29a23039291138f989c7c2ce

With this commits the peak32() output will, probably, still come up, but
these errors should not be fatal and the device should still be usable.

Regards,
- Nicolas
