16:59 <whitequark> marcan: esden: any source for the absolute cheapest *double sided* flex PCBs?

16:59 <whitequark> even worse actually, double sided flex PCBs with plated through holes

17:01 <whitequark> ah, dirtypcbs does flex

17:03 <whitequark> hm, pcbway does too at the same cost

17:03 <whitequark> holy shit

17:03 <whitequark> they do SIX LAYER flex?!

17:05 <Hellsenberg> that's a lot of layers to flex

17:05 <Hellsenberg> I wonder how they do to avoid the layers from separating when flexed

17:55 <whitequark> marcan: also, poke

18:06 <Hellsenberg> 3~

18:06 <Hellsenberg> oops

18:38 <whitequark> gruetzkopf: ping

18:38 <whitequark> can you please push your changes?

18:38 <whitequark> it's been weeks

20:49 <marcan> whitequark: I know I owe you a refactor of the expanders, it's in the queue. still juggling through some crap this week with deadlines, will try to find time.

20:52 <whitequark> marcan: ack

21:14 <gruetzkopf> sorry, it's been faar more than busy

22:18 <whitequark> gruetzkopf: I think I reproduced your changes

22:18 <_whitenotifier> [GlasgowEmbedded/Glasgow] whitequark pushed 3 commits to master [+0/-0/±4] https://git.io/fjvFk

22:18 <_whitenotifier> [GlasgowEmbedded/Glasgow] whitequark b906631 - gateware.clockgen, applet: fix typos.

22:18 <_whitenotifier> [GlasgowEmbedded/Glasgow] whitequark cf47a3a - applet.interface.spi_master: use ClockGen.

22:18 <_whitenotifier> [GlasgowEmbedded/Glasgow] whitequark e5f9ea9 - firmware: use PF instead of EF/FF and INFM1/OEP1. "NFCI."

22:19 <gruetzkopf> yeah, looks similar enough

22:20 <gruetzkopf> what was your reason for doing this anyways?

22:21 <_whitenotifier> [Glasgow] Success. The Travis CI build passed - https://travis-ci.org/GlasgowEmbedded/Glasgow/builds/508120410?utm_source=github_status&utm_medium=notification

22:21 <whitequark> gruetzkopf: https://github.com/GlasgowEmbedded/Glasgow/issues/89

22:21 <whitequark> it's necessary to increase latency by one cycle further

22:21 <whitequark> but that's impossible

22:21 <gruetzkopf> ah, so you can move timing around more easily

22:22 <whitequark> now, yeah

22:56 <_whitenotifier> [GlasgowEmbedded/Glasgow] whitequark pushed 3 commits to master [+0/-0/±4] https://git.io/fjvFM

22:56 <_whitenotifier> [GlasgowEmbedded/Glasgow] whitequark ed609c7 - applet.interface.spi_master: lazily dump hex data.

22:57 <whitequark> gruetzkopf: this should fix the hangs you've been seeing

22:59 <gruetzkopf> give me one moment to dig out microb cable

23:28 <whitequark> gruetzkopf: ping

23:28 <gruetzkopf> cable located, git pull running

23:37 <_whitenotifier> [GlasgowEmbedded/Glasgow] whitequark pushed 1 commit to master [+0/-0/±1] https://git.io/fjvb3

23:45 <gruetzkopf> https://paste.debian.net/plainh/4502008d did i manage to make my install inconsistent?

23:45 <gruetzkopf> (selftest passes)

23:46 <whitequark> gruetzkopf: try `make -C firmware load` then `glasgow run benchmark`

23:48 <gruetzkopf> ok, that's consistent with the behaviour before the patch. let me stare at the patches some more

23:48 <gruetzkopf> I: g.applet.internal.benchmark: running benchmark mode source for 4.000 MiB

23:48 <gruetzkopf> I: g.applet.internal.benchmark: running benchmark mode sink for 4.000 MiB

23:48 <gruetzkopf> E: g.applet.internal.benchmark: mode sink failed!

23:48 <gruetzkopf> I: g.applet.internal.benchmark: running benchmark mode loopback for 4.000 MiB

23:48 <gruetzkopf> I: g.applet.internal.benchmark: mode source: 23.863 MiB/s

23:48 <gruetzkopf> __hangs__

23:49 <whitequark> ok

23:49 <whitequark> still broken

23:49 <whitequark> that's really bad

23:50 <whitequark> i have absolutely no idea what to do now

23:50 <gruetzkopf> it _might_ just be a faulty board?

23:50 <whitequark> unlikely

23:50 <whitequark> i observe visual snow with video-rgb-input applet

23:50 <whitequark> which is digital

23:50 <gruetzkopf> i'lll page jn, who has a board from the same run

23:50 <whitequark> that means *something* is fucked up with timings

23:50 <whitequark> like, i know for sure it's fucked up

23:53 <_whitenotifier> [Glasgow] whitequark commented on issue #89: Use SB_GB_IO instead of SB_IO+SB_GB - https://git.io/fjvb4

23:53 <whitequark> tnt: could you take another look at the FX2 interface?
