cr1901_modernmithro: https://github.com/fupy/issues-wiki/issues/9#issuecomment-369774792 Do you have any idea what's wrong? Sounds like the Makefile needs work, but I don't have time to check right now00:38

mithrocr1901_modern: It's probably been fixed if we just push a new litex-buildenv there?00:39
cr1901_modernWhat does litex-buildenv have to do w/ fupy00:40

cr1901_modernI see00:45
cr1901_modernmithro: I'd like to get the litex version used by litex-buildenv bumped tonight, but I need a stopgap solution to the path problems. Personally I think we should just remove the "-Ob toolchain_path /opt/Xilinx" from settings.sh for now00:46
cr1901_modernor reluctantly, perhaps the change in litex.build causing the issues should be reverted if HDMI2USB/litex-buildenv hard-depend on the path behavior00:57
cr1901_modernmithro: This is none of my business, but I'll ask anyway. Why do you star your own repos?01:17
JoelwIt's like how buskers always put some of their own money in the hat! :)01:23

cr1901_modern_florent_: https://hastebin.com/yefawetofo.rb This is what I get for testing bitslip on the arty s717:33
cr1901_modernBased on these results, I should choose a bitslip of 3, delay of 17?17:33
cr1901_modernor 16*17:33
cr1901_modernmithro/_florent_: Pretty confident the litex port for arty_s7 works properly, including DDR. The A7 PHY was reusable.18:11
_florent_cr1901_modern: good! (yes bitslip of 3 / delay of 16 or 17 will be fine)18:16
mithrocr1901_modern: \o/18:18
mithro_florent_: Any chance you could take a quick look at CarlFK[m]'s EDID issue? My current guess is that it got broken with changes to support Bunnie18:19
cr1901_modern_florent_: For now I instructed the person actually porting arty_s7 to litex_buildenv to use 14.18:19
cr1901_modernShould we alias S7 PHY to A7 PHY?18:19
_florent_cr1901_modern: why using 14 that is clearly not the middle of the sampling window?18:20
cr1901_modern_florent_: B/c I'm an idiot18:21
mithroCarlFK[m]: Can you see if the edid is broken on the Atlys as well as the Opsis? It sounds like it is?18:21
CarlFK[m]mithro (IRC): I am getting different edid stuff on the Atlys - im a little lost about what I am looking at18:22
_florent_cr1901_modern: it will probably work, but you should use the middle of the window, more change to get reliable results between fpga boards/builds18:23
cr1901_modern_florent_: Right, updated my comment to tell the porter to use 1718:23
CarlFK[m]Opsis saw FF FF FF edid and reported it bad - Atlys says "input0 port has no EDID capabilities"18:23
CarlFK[m]mithro (IRC): which Joel is the Joel I need to bug about the vizzini code?  (it seems to be working)18:25

CarlFK[m]I suspect I am getting the last edid from when something was pluged in.  but its hard to keep track when I don't know if something is really sending FFs or if it is having trouble reading19:16
