00:24 <GitHub143> [artiq] whitequark commented on issue #908: The boot messages are displayed by the `read_bitslip` and `read_delays` functions. Memory check likely fails because write leveling exists for a reason. https://github.com/m-labs/artiq/issues/908#issuecomment-366833431

03:00 <sb0> whitequark, any update on the camera driver?

03:50 <whitequark> no. I've been looking into the buildbot breakage

04:17 <sb0> windows python?

04:22 <whitequark> yes, and other issues too

08:01 <GitHub49> [artiq] sbourdeauducq commented on issue #902: @jonaskeller How are things (flashing and panic) with a recent artiq-4 package from master? If everything works I'll backport the changes to release-3 and make a new release. https://github.com/m-labs/artiq/issues/902#issuecomment-366895441

09:16 <sb0> rjo, FYI I'm going to order another kasli for m-labs hk, it's definitely more pleasant to debug/develop drtio there than on kc705 (transceiver bugs) or sayma (no comment), and one of the two kasli we have atm will go to china soon

09:20 <sb0> those transceivers also seem to guzzle power. heat-sinked FPGA is at 71C with ethernet and drtio running...

09:23 <rjo> sb0: ack. it's a really nice board.

09:24 <rjo> sb0: be careful with esd though (i2c switch seems sensitive) and i put a 25x25mm 12v fan onto the heat sink. with opticlock it's now at 48c. the amount of LVDS buffers is driving power usage.

09:25 <rjo> sb0: care to do a quick code review of the new spi core?

09:26 <GitHub38> [misoc] jordens deleted kasli-100mhz at 7126ec4: https://github.com/m-labs/misoc/commit/7126ec4

09:27 <sb0> ok

09:27 <GitHub121> [misoc] jordens created spi2 (+1 new commit): https://github.com/m-labs/misoc/commit/e79ea98b2a70

09:27 <GitHub121> misoc/spi2 e79ea98 Robert Jordens: spi2: new spi master core...

09:27 <rjo> sb0: i'll stage that without disturbing the old core and then transition the upper layers one by one.

09:28 <sb0> rjo, is the oxford ad9910 support complete with the current code?

09:31 <rjo> documentation still. and i couldn't get it to work at full speed yet (62.5 MHz SPI clock) which bothers me. and it doesn't initialize and lock the plls correctly from time to time.

09:32 <GitHub175> [misoc] jordens force-pushed spi2 from e79ea98 to f5b5923: https://github.com/m-labs/misoc/commits/spi2

09:32 <GitHub175> misoc/spi2 f5b5923 Robert Jordens: spi2: new spi master core...

09:36 <sb0> do you suspect spi core bugs?

09:37 <rjo> yes. gateware or mis-usage in the rtio layer or the coredevice support.

09:38 <rjo> and the spi core is also failing timing sporadically on kasli. and vivado complains (probably rightly so) about lack of output/input buffers.

09:41 <sb0> bb-m-labs, stop build artiq drtio tests

10:01 <GitHub59> [artiq] hartytp commented on issue #908: @enjoy-digital did you have a chance to fix the timing issues with serwb that @sbourdeauducq mentioned? I know that these are unlikely to be the cause of the SDRAM issues, but it's probably a good idea to mop up all the known issues as a starting point to fixing this.... https://github.com/m-labs/artiq/issues/908#issuecomment-366926989

10:03 <hartytp> rj0: do you have a pair of a Kasli with DRTIO working? If so, would you be interested in doing a phase stability measurement at some point soon? Idea would be to put the output of the Si5324 clocks onto a 2-channel ADC and do a long-term (hours) phase drift measurement

10:03 <hartytp> let the DRTIO master free-run and compare the phase wander of the locked slave DRTIO clock relative to the master
