Hi Mark,
It is the simplest.  You can always play around with the source code to comment out the lines that do the ADC self test temporarily.
Regards,
Michael

Hi Mark,
Update UHD to a newer version.  The head of the maint branch or the latest 3.10.2.0 release should work.  The ADC self test is skipped when supplying "recover_mb_eeprom" as of UHD 3.10.0.0.
Regards,
Michael

Just following up on the message I sent out 8 days ago.  Does anyone have any resolution to this issue?  I have seen other people have the problem, but have yet to find a fix.

Thanks

All,


I am getting the following output when trying to recover the mb EEprom.  Can anyone be of assistance?

Thank you

Mark
