02:37 <sb0> hartytp: let's make a block diagram of the whole clock recovery/PLL/DDMTD system

06:32 <sb0> rjo: are the user_led really important in VLBAIMaster and VLBAISatellite?

08:16 <bb-m-labs> build #2467 of artiq-board is complete: Success [build successful] Build details are at http://buildbot.m-labs.hk/builders/artiq-board/builds/2467

08:19 <bb-m-labs> build #2943 of artiq is complete: Failure [failed python_unittest_2] Build details are at http://buildbot.m-labs.hk/builders/artiq/builds/2943 blamelist: Sebastien Bourdeauducq <sb@m-labs.hk>

11:27 <hartytp> sb0: yes, I'll try to do that this weekend

11:28 <hartytp> related, I'd like to write up my notes on DRTIO clocking somewhere upstream (otherwise I have to keep going back to the source code and UGs to remind myself how it works each time I have an issue)

11:29 <hartytp> maybe add a BD as well

11:29 <hartytp> where would you want to see that kind of thing? Master manual? Wiki?

12:19 <rjo> sb0: can go if the sfp leds are there

12:47 <sb0> rjo: the SFP LEDs indicate DRTIO link status

12:47 <sb0> hartytp: thanks

12:47 <sb0> hartytp: in the manual

12:47 <sb0> hartytp: by the way, have you looked at the current DRTIO synchronization performance with the Si5324?

12:55 <hartytp> sb0: may be able to do that on monday

12:56 <hartytp> usual snafu with sayma: none of our boards work in the rack right now

12:56 <hartytp> joe sent me two AMCs, one has a sticker saying 3v3 broken but seems to work fine

12:56 <hartytp> the other one doesn't turn on even out of the rack

12:56 <hartytp> need to upgrade vivado

12:56 <hartytp> etc

12:56 <sb0> yeah, that's still going on...

12:56 <hartytp> what do you think about the idea of unifying "sayma on a eurocard" with "fast Kasli servo"?

12:57 <sb0> we need to get WUT to identify the exact causes of those broken boards, I suspect not all of it is "damaged during transport" and it'll bite us again in v2

13:00 <hartytp> yes

13:00 <hartytp> but, there comes a point when it's best to just get on with v2.0

13:00 <hartytp> even if it has bugs

13:01 <hartytp> debugging on v2.0 and then moving quickly onto 2.1 may be more efficient than debugging onto v1.0

13:02 <sb0> hmm... those problems have been wasting a lot of dev time

13:03 <hartytp> yes

13:03 <hartytp> fwiw, I've been really impressed with how creotech are handling booster

13:04 <hartytp> that gives me some hope that they will find and fix at least some of the remaining issues before shipping sayma to us
