<cladamw> morning !
<cladamw> wpwrak, if still reserve un-used fpga pin, you meant to connect limiter switch's fault pin ? right ?
<wpwrak> yeah. and maybe the enable pin as well.
cjdavis has joined #milkymist
<wpwrak> enable would have three functions: 1) turning off the DCC5V if we want to do this for some reason. 2) re-enable DCC5V after a voltage inversion (output > input). 3) in case we have troubles sourcing the right chip, increase the choice for alternatives.
<wpwrak> 1) and 2) seem unlikely or exotic. but 3) could be interesting.

<cladamw> Good, Ven can be worked with 3.3V directly. Vfault don't know...checking...
<cladamw> Fault is open-drain, also good news for 3.3V.
<davidc__> Hey; migen looks pretty interesting - is it in a state where non-milkymist-people should start writing code against it, or is a lot of change in the interfaces expected?

<wpwrak> xiangfu: while you're at it, how about s/successfull/successful/ ? :)
<xiangfu> wpwrak, you mean the daily build?
<wpwrak> the message in the Makefile
<wpwrak> the word "successfull" doesn't exist. it's "successful". a rather common mistake :)
<xiangfu> wpwrak, thanks. fixed
<GitHub65> [scripts] xiangfu pushed 1 new commit to master: http://git.io/3Tmq2w
<GitHub65> [scripts/master] fix typo - Xiangfu Liu
<wpwrak> thanks ! :)
<xiangfu> wpwrak, when we can merge the 'imaginarium' branch to master?
<wpwrak> it's already there, isn't it ?
<wpwrak> i just keep it around in case i want to do more experiments there.
<xiangfu> wpwrak, oh. sorry. yes. merged at 02-18.
<xiangfu> wpwrak, I have to find out what wrong with my usb-midi(ICON) .
<wpwrak> so it's still not working. hmm ....
<wpwrak> maybe try some of my binaries. they're a bit older but at least the soc shouldn't have changed: http://downloads.qi-hardware.com/people/werner/tmp/m1-20120126/
<xiangfu> I am reflashing with 'http://fidelio.qi-hardware.com/~xiangfu/build-milkymist/milkymist-firmware-20120222-1455/' now. for cleanup and sync all with latest code.
<wpwrak> icon should work with these
<xiangfu> wpwrak, works with 'm1-20120125'
<wpwrak> victory !!! ;-)
<xiangfu> ok. it's not soc.fpg problem.
<xiangfu> so must be flickernoise again.
<wpwrak> if something usb fails, that would point to a broken milkmist.git (softusb) -> rtems -> flickernoise path
<wpwrak> (and it's good that it isn't a soc problem. because i wouldn't have known where to look in this case :)
<wpwrak> (path) actually, it's milkymist.git (softusb) -> milkymist.git (libhal) -> rtems -> flickernoise
<wpwrak> way too complicated :)
<xiangfu> wpwrak, we have some regression on display by using 13.4 Xilinx ISE. too bad.
<xiangfu> wpwrak, the screenshot look ok.
<xiangfu> but my monitor shows something wrong. :(
cjdavis has joined #milkymist
<xiangfu> let's start with milkymist.git(softusb) :)
<wpwrak> display regression sounds nasty
<xiangfu> it's like the 'GREEN' shift to left.
<wpwrak> hmm. that sounds a bit like the return of the gradients issue i reported a while ago. it eventually just disappeared for some reason.
<xiangfu> yes. there is a gradient line of green points on button and blank. I will take a picture later.
cladamw has joined #milkymist
<xiangfu> wpwrak, found the problem.
<xiangfu> wpwrak, I miss your patch on rtems.
<xiangfu> must be something wrong with the build script file
<GitHub199> [scripts] xiangfu pushed 1 new commit to master: http://git.io/1b5-5Q
<GitHub199> [scripts/master] fix the quilt apply patch problem. pop -a -f before push - Xiangfu Liu
<xiangfu> let's wait next build. try to find out the 13.4 display regression. :)
* xiangfu have the usb-midi working great. try to write a demo on ICON :)

<xiangfu> fix my last commit. that wrong with 'make tools' since there is a folder named 'tools'

<wpwrak> xiangfu: (quilt issue found) great !
<xiangfu> wpwrak, yes. I am play the wheel.fnp now. try to write another demo for ICON :)
<wpwrak> great ! the more demos, the better :)

<lekernel> davidc__: feel free to write code against it. no experimental software = no fun.
<davidc__> lekernel: heh, that was the general assumption. I'm quite happy to deal with bleeding-edgeness / bughunting; I just don't want to write against something that is definitely going to be rewritten :)
<qi-bot> The firmware build was successful, see images here: http://fidelio.qi-hardware.com/~xiangfu/build-milkymist/milkymist-firmware-20120223-0959/
<lekernel> davidc__: there are no major rewrites planned
<lekernel> (yet *g*)
<davidc__> lekernel: cool. One area I'd like to develop is automatic clock-crossing-logic generation; since thats a tedious PITA
<lekernel> hmm... everything in migen is designed for synchronous circuits
<lekernel> also this stuff is often architecture-dependent
<davidc__> lekernel: yeah to both. I haven't figured out if the first can be worked around

<wpwrak> funny. i had "wheel" running for about a day and the two differ by about 4 frames. that twice the exactly some calculations, although with a slight difference in initial angle.

<lekernel> good work getting in there :) but I wonder what sort of outcome can be expected from such events
<rejon> Its true, but its so easy just to stay in free software world too, so I wonder what happens there?
<rejon> Its always hard work getting to know new people and scene
<rejon> reminds me I need to followup with them
<rejon> I'm working on some more events, but will refrain talking about until more real ;)
<lekernel> yes sure, always good to go and see what other people are doing

* lekernel is successfully operating the DDR command signals at 166MHz
<lekernel> seems the read path is working too, but there's some data alignment issue

<GitHub186> [milkymist-ng/master] dfii: set data mask - Sebastien Bourdeauducq
<lekernel> yay! almost works. and data doesn't get corrupted.
<kristianpaul> bravo ! :)
<lekernel> it reads/writes the same data, only at the wrong places, and with inserted zero's in some cycles...
<lekernel> sounds like relatively easy bugs ...

<lekernel> hm probably the serdes are acting up
<lekernel> or the bufpll
<lekernel> instead of writing 0001020304050607f0f1f2f3f4f5f6f7
<lekernel> I get 04050607f0f1f2f3f4f5f6f7f4f5f6f7 and a similar bug in the read path
<lekernel> (I can deduce what got actually written by reordering the bursts)
