| wpwrak | cladamw: what operating temperature do we assume ? | 01:23 |
|---|---|---|
| wpwrak | (ambiental) | 01:23 |
| wpwrak | (well, ambiental ... inside the box :) | 01:23 |
| wpwrak | cladamwa: what operating temperature do we assume ? | 01:24 |
| cladamwa | wpwrak, hi suppose it still works for 70 degree, but we've never done more analysis on M1. | 01:25 |
| wolfspraul | cladamwa: hi good morning :-) | 01:26 |
| wolfspraul | I see you online since 6 AM or so - you start that early? | 01:26 |
| cladamwa | no baker test, no design analysis first | 01:26 |
| wolfspraul | I was a little worried that R4 proves so stressful that you cannot sleep :-) | 01:26 |
| cladamwa | wolfspraul, ah ? no, maybe only am 8:40 | 01:27 |
| wolfspraul | good | 01:27 |
| wolfspraul | :-) | 01:27 |
| wpwrak | wolfspraul: or so invigorating that he has no need for that much sleep ;-) | 01:27 |
| cladamwa | wolfspraul, ha..no, i'm happy that now joerg & werner jumped into design stage/verification which i was weak. ;-) | 01:28 |
| wolfspraul | wpwrak: can you do me a favor and check what type of riitek/remote keyboard you have? | 01:29 |
| wolfspraul | turn it around - do you see any label or marking? | 01:29 |
| cladamwa | wolfspraul, wpwrak, i git cloned wernermisc, maybe include me into member ? | 01:29 |
| wolfspraul | cladamwa: done | 01:30 |
| cladamwa | so i can update _r4.csv just in case when i update it. | 01:30 |
| wolfspraul | you need to clone again with write permission | 01:31 |
| cladamwa | wolfspraul, thanks. | 01:31 |
| cladamwa | yeah...long time no use, i'll do it again later. | 01:31 |
| wpwrak | wolfspraul:model RT-MWK01 | 01:34 |
| wolfspraul | ah perfect, the exact same we will inlude | 01:34 |
| wolfspraul | include | 01:34 |
| wpwrak | wolfspraul: (non-BT 2.4 GHz, laser pointer) | 01:34 |
| wpwrak | hah :) | 01:35 |
| wolfspraul | we compared easily 10-15 different ones, also different form factors etc. | 01:35 |
| wpwrak | i think i would have tried to lose the laser pointer :) | 01:35 |
| wolfspraul | and in the end come back to the first one we started with, urgh :-) | 01:35 |
| wpwrak | wow, quite a lot | 01:35 |
| wolfspraul | but that's ok, if you knew before what you know later something would be wrong... :-) | 01:36 |
| wolfspraul | riitek is nice, other vendors are quro, zoweetek, unisen, anterton | 01:36 |
| wolfspraul | but they all have quality issues imho | 01:36 |
| wpwrak | my riiteks are still going well. they must be something like 2 years old now | 01:38 |
| wpwrak | very light use, though | 01:38 |
| wpwrak | cladamwa: regarding the TPS76301T (U12, etc.) which dissipation rating would we apply ? Low K or High K ? or something else ? | 01:52 |
| cladamwa | High K suppose. | 01:56 |
| cladamwa | chip vendor produced reference design(multilayers and 2 layers) about measurement to develop dissipation rating table i believe. | 02:00 |
| wpwrak | hah. the power supply is more fun than the previous sheets :) | 02:01 |
| wpwrak | yes, page 3 describes the high/low K boards | 02:01 |
| roh | wpwrak: hey... i stumbled onto a ar6k fw lately | 02:06 |
| roh | one which does ap mode | 02:06 |
| roh | any interrest or know somebody who does? | 02:07 |
| wolfspra1l | painful memories :-) | 02:07 |
| roh | i know. | 02:08 |
| wolfspra1l | and this stuff is deader than dead too :-) | 02:08 |
| wolfspra1l | don't you think? | 02:08 |
| roh | well.. which chipsets for wifi you know of for < usb/PCIe ? | 02:09 |
| wolfspra1l | oh sure | 02:09 |
| roh | means sdio or so... | 02:09 |
| roh | not that much to choose from | 02:09 |
| wolfspra1l | but the fate of this path of development was decided what. 2-3 years ago? | 02:09 |
| wolfspra1l | something like that | 02:09 |
| wolfspra1l | now they go full power to 802.11ac and more | 02:10 |
| roh | dunno. i just know that i find it in todays devices here and there | 02:10 |
| roh | phones and such. android devices. tablets | 02:10 |
| roh | such stuff | 02:10 |
| wolfspra1l | I certainly don't know anyone still actively on this, but I also moved my attention elsewhere years ago. | 02:12 |
| wpwrak | what is an "ar6k" ? doesn't sound edible | 02:15 |
| wolfspra1l | from the perspective of a wifi chip maker, I think it's safe to say that the experience of the last 5-10 years tells them that the additional momentum from open source drivers does not match the capital needs to compete in the ongoing speed, cost and low-power race | 02:19 |
| wolfspra1l | in other words - open source drivers are a distraction | 02:20 |
| wolfspra1l | (for them) | 02:20 |
| wolfspra1l | I could not go with a straight face to Broadcom, Marvell, MediaTek, Qualcomm, Intel or the other Asian corps and tell them that they should spend brain cells on open source drivers :-) | 02:22 |
| wolfspra1l | (for wifi) | 02:22 |
| wpwrak | intel may be a good candidate. with things moving into the core, closed wifi taints the core | 02:36 |
| wolfspra1l | don't understand | 02:36 |
| wolfspra1l | what do you want to propose to Intel? | 02:36 |
| wolfspra1l | I think their integrated wifi is one of the best supported in Linux now, indeed | 02:37 |
| wolfspra1l | we have some contacts 'into' Intel, but it's a large corporation and my expectations for getting anything tangible out of 'Intel' are zero :-) | 02:37 |
| wolfspra1l | I have no idea now Intel sees the wifi thing, and I am sure even at Intel there are at least 10 different strategies about it, each one thought through in sophisticated ways, of course. | 02:38 |
| wolfspra1l | they had their best year ever last year :-) | 02:39 |
| wolfspra1l | I just want to be hired by Intel and become a futurologist. | 02:43 |
| wolfspra1l | at least my monthly paycheck is safe until (early) retirement | 02:43 |
| wpwrak | dunno the wifi situation. just commented that intel should have an interest in being at good terms with open source also on the wifi front. if they already are, even better. | 02:44 |
| wolfspra1l | I think so, yes | 02:44 |
| wolfspra1l | but of course Intel wifi tech is integrated with pretty much the largest chips you can imagine | 02:44 |
| wolfspra1l | good luck trying to get that tech out there into an embedded product | 02:45 |
| wpwrak | and there i was, thinking you were pining for a job at sisvel :) | 02:45 |
| wolfspra1l | futurologist at Intel | 02:45 |
| wolfspra1l | that'd be it | 02:45 |
| wpwrak | (chips) yeah. if course, they'd be really happy if you manage to pull that off ;-) | 02:45 |
| wolfspra1l | more money than brain, just think and think and think more about the future. | 02:45 |
| wolfspra1l | the only risk is depression | 02:46 |
| wolfspra1l | if you have a notebook with integrated intel wifi, be happy | 02:46 |
| wolfspra1l | that's my bottom line | 02:46 |
| wolfspra1l | I'm not going to over-strategize this stuff... | 02:47 |
| Thihi | I replace my notebooks wifi with intel models usually. Gotta love mini-pci-e. | 02:53 |
| Thihi | Usually == when it's doable. | 02:56 |
| Thihi | Like in my netbook, and in my other laptop, and two of my previous ones. | 02:56 |
| Thihi | :) | 02:56 |
| wolfspra1l | maybe the enormous investments that are needed in that competition lead to chips that are standardized at a much lower level that is a better starting point for open hardware | 02:59 |
| wolfspra1l | I will keep my eyes open for that | 03:00 |
| wolfspra1l | (and needless to say we will need the Milkymist SoC for that stuff :-)) | 03:01 |
| frankD2 | hey guys, where do i start if I want to port effecTV as a feature ? | 06:32 |
| wolfspra1l | never heard of that but looks nice (reading homepage now) | 06:34 |
| wolfspra1l | last news update was over 5 years ago, that makes me feel a little better about the Qi news :-) | 06:35 |
| wolfspra1l | without looking at the codebase now, my guess is if you are trying to bring this to Milkymist One, you best start from scratch first, then over time as you understand Milkymist/Flickernoise better and better, maybe there are bits and pieces you can reuse | 06:35 |
| wolfspra1l | certainly knowledge | 06:35 |
| wolfspra1l | if your goal is to 'port' the entire codebase, that will be a long and tedious path since it sounds like you first need to help making the switch from rtems to Linux, then probably help with the currently broken C++ compiler, and then most likely many other things... | 06:36 |
| wolfspra1l | I suggest taking M1 as-is and then trying to apply things learnt from EffecTV | 06:36 |
| frankD2 | got that idea while watching RHCP- The zephyr song. | 06:38 |
| wolfspra1l | do you have a Milkymist One? | 06:57 |
| frankD2 | oh yeah, it's two days old. lol. Thanks dude, it's been great so far. Sorry for not keeping you informed that i've received the package. | 07:10 |
| wolfspra1l | oh, nice :-) | 07:11 |

| cladamw | wpwrak, i got Error 1 after I updated milkymist_one_bom_r4.csv under your tree/master/m1r4/dsv , i think that i was wrong that i shouldn't have updated this file in this way, right ? | 10:43 |
| wpwrak | cl... grr | 11:21 |
| qi-bot | The firmware build was successful, see images here: http://fidelio.qi-hardware.com/~xiangfu/build-milkymist/milkymist-firmware-20120315-1046/ | 11:25 |
| wpwrak | ah, here he is :) | 11:32 |
| wpwrak | 1) you should test before committing :) | 11:33 |
| cladamw | 1) yup..stupid :( | 11:33 |
| wpwrak | 2) the problem are line breaks embedded in some fields | 11:33 |
| wpwrak | maybe we can fix that at the source ... one is | 11:33 |
| wpwrak | "ACâ~@~Y97 Revision 2.1 Audio CODEC with SPDIF Output | 11:34 |
| wpwrak | then there is a newline | 11:34 |
| wpwrak | ","48-lead TQFP | 11:34 |
| wpwrak | another newline | 11:34 |
| wpwrak | ",,5.030,5.030,,,"NOT START", | 11:34 |
| cladamw | Died at ./bomshelf line 10, <> line 2. | 11:35 |
| wpwrak | yes, that's because the .csv is incorrectly formatted - due to the newlines inside fields | 11:35 |
| wpwrak | if you delete the last characters in fields G2 and H2, that should get rid of the newlines | 11:38 |
| wpwrak | maybe also change the ' in G2 (AC'97) to ASCII and not the non-ASCII lookalike | 11:39 |
| cladamw | okay... i do it | 11:39 |
| wpwrak | let's see if there are more ... | 11:40 |
| wpwrak | D29 and G29. D29 at the end, G29 between ...49SMD and , 20PF... | 11:43 |
| wpwrak | then bomshelf should be happy | 11:43 |
| wpwrak | it will warn about three cases of "-", but that's okay | 11:44 |
| cladamw | phew~ lots of newlines, now it searching pdf... :-) | 12:05 |
| cladamw | it means i have to fill *.ods up very carefully. :( | 12:08 |
| wpwrak | just don't insert newlines ;-)) | 12:18 |
| wpwrak | pity that *office doesn't keep them out on its own | 12:18 |
| wpwrak | well, i suppose i could also teach bomshelf to handle them | 12:19 |
| cladamw | wpwrak, you set a .gitignore for BOOKSHELF on your own directory, right ? | 12:23 |
| wpwrak | no. i just don't git add BOOKSHELF :) | 12:30 |
| wpwrak | and having a bit of noise at the bottom of the commit "form" doesn't bother me | 12:31 |
| cladamw | okay :-) | 12:31 |
| wpwrak | whee, works ! :) | 12:34 |
| cladamw | wpwrak, :) thanks for leading me to remove the err of embedded newlines. | 12:37 |
| wpwrak | thanks for fixing them ! ;-) | 12:38 |
| Artyom | Hello to everyone. I want to give a link to the fpga-board that I find interesting. May be it can be interesting to someone else too: http://www.enclustra.com/en/products/ | 17:55 |
| Fallenou | [6~[6~[6~/win 57 | 17:58 |
| lekernel | Artyom: what's particularly interesting about it? | 17:59 |
| lekernel | and which board are you talking about :) | 18:00 |
| Artyom | For me there are several points (Among these boards I mainly looked at "Mars PM3" + "Mars MX2") 1. I don't know any other board with Gigabit Ethernet + USB-FX3 interfaces. | 18:03 |
| Artyom | 2. I liked their idea of spliting FPGA-system on 2 parts: mother-board + FPGA-board. | 18:04 |
| Artyom | 3. Standard FMC connector support. | 18:04 |
| Artyom | I understand that most of these points stand in the side of milkymist. But these boards attracted my attention and I hope they can be interesting to someone else. | 18:06 |
| lekernel | what are you planning to do with them? | 18:07 |
| Artyom | I need something to transfer data from high-speed ADC to PC for post-processing. I think I described my task earlier. These boards seems to be the best alternative for my task. (Until I wouldn't try to develop something similar by myself ;) ) | 18:10 |
| Artyom | I also keep in mind building a gps/glonass/any_other_gnss-receiver on a fpga-board. This board can be used for that too as my digilent-board (based on s3e500) is too small. But anyway I will try to use MM SoC on it (of course if I will get them...) | 18:15 |
| larsc | <shameless plug> Artyom: Have you considered ADIs high speed data converter FPGA solutions? </shameless plug> | 18:18 |
| Artyom | larsc: Do you mean some ADIs ADC or some demo-board? | 18:20 |
| larsc | Artyom: http://wiki.analog.com/resources/alliances/xilinx and http://wiki.analog.com/resources/alliances/altera | 18:23 |
| kristianpaul | hi Artyom | 18:26 |
| Artyom | kristianpaul: hi :) | 18:27 |
| kristianpaul | ah USB-FX3 i tought you liked that a lot :) | 18:27 |
| kristianpaul | most of these points,hmm milkymsit dont have a fast tranfer bus for comunicating with host computer | 18:28 |
| kristianpaul | at least can beat a usb-fx* thing | 18:28 |
| kristianpaul | of coruse in the sense of open hardware ;-) | 18:29 |
| kristianpaul | s/course/course | 18:29 |
| kristianpaul | Artyom: how afortable are those enclustra boards? | 18:30 |
| kristianpaul | lets see if there is one based on spartan-6.. | 18:30 |
| Artyom | larsc: I didn't search for FMC solutions yet. Because I still don't have exact plan of solving my task. I slowly worked on developing my custom solution. I thought to split design on two parts: ADC-board and FPGA-board connected with each other through SerDes. So I was mainly focused on ADC-boards design and FPGA-boards design. I roughly chose basic components including ADC, FPGA, memories... | 18:31 |
| Artyom | ...and so on... | 18:31 |
| kristianpaul | ha cool the fpga is plugable ;-) | 18:31 |
| kristianpaul | oh wow artix 7 ! | 18:31 |
| kristianpaul | now where are the specs and the prices... | 18:32 |
| Artyom | kristianpaul: I know very little about these boards. I found them couple of hours ago... | 18:32 |
| kristianpaul | ok ok :) | 18:32 |
| kristianpaul | btw had you looked at gpl-gps namuru port ? | 18:33 |
| kristianpaul | looks very promising for porting | 18:33 |
| kristianpaul | it uses ecos threads.. still need see how adapt to rtems | 18:33 |
| kristianpaul | oh, this is milkymist ;-) | 18:34 |
| kristianpaul | nice read you here :) | 18:34 |
| Artyom | yes, I looked a little at gpl-gps namuru port. But I didn't have time to study it deeply. Anyway it's a working port. So it's the best starting point. | 18:36 |
| kristianpaul | indeed | 18:37 |
| kristianpaul | ah | 18:39 |
| kristianpaul | Artyom: had you looked at Icarus board? | 18:39 |
| kristianpaul | have lots of pins | 18:39 |
| kristianpaul | perhaps you can wire a USB-FX3 board to it | 18:39 |
| kristianpaul | also is dual core LX150 spartan6 ! | 18:40 |
| kristianpaul | Artyom: http://en.qi-hardware.com/wiki/Icarus | 18:40 |
| Artyom | No, I didn't. But building custom USB-FX3 board is too expensive (if we compare it to the products that I found). FX3 requires expensive pcb-design. | 18:43 |
| kristianpaul | ok, what about buy it separatellit? | 18:44 |
| kristianpaul | separatelly* | 18:45 |
| Artyom | spartan6 lx150. Real beast ;) | 18:45 |
| Artyom | two FPGA cost as 2 MM one ;) | 18:46 |
| kristianpaul | btw from your university can you get this http://www.ion.org/search/view_abstract.cfm?jp=p&idno=8133 ? | 18:46 |
| kristianpaul | I was introduced to Michele Bavaro, and he mention some guy working on another gp2021 correlator implementaation | 18:47 |
| kristianpaul | based on that paper about | 18:47 |
| kristianpaul | Yacine Adane, University of Westminster, | 18:48 |
| kristianpaul | but they have the old idea of implementing tracking loops and PVT on cpu, | 18:49 |
| kristianpaul | he | 18:49 |
| Artyom | I'll try to find this paper. | 18:50 |
| kristianpaul | i wonder if you are aware of that, just telling, may be may be not they found similar problems you had with the arm fpga combo.. | 18:50 |
| kristianpaul | who knows.. | 18:50 |
| kristianpaul | paper, good, perhaps you look it interesting | 18:50 |
| Artyom | I didn't know about Yacine Adane ;) | 18:52 |
| kristianpaul | we should :) | 18:52 |
| kristianpaul | btw this board comparisong is part of a short term sourcing plan? | 18:53 |
| Artyom | They go traditional way. I know working receivers based on spartan3-correlator + TMS DSP | 18:53 |
| kristianpaul | i mean buy | 18:53 |
| Artyom | I don't know. I will offer this solution to my employer ;) | 18:54 |
| kristianpaul | I see :) | 18:54 |
| kristianpaul | once i considered buying this http://shop.ztex.de/product_info.php?cPath=22&products_id=73&osCsid=a906b324dc0113bd7b1fa6825fdea314 | 18:54 |
| Artyom | Sorry, kristianpaul I need to leave now... | 18:55 |
| kristianpaul | oh sure | 18:55 |
| kristianpaul | leave ! | 18:55 |
| kristianpaul | :-) | 18:55 |
| Artyom | larsc: that for the links. | 18:55 |
| kristianpaul | read you later | 18:55 |
| Artyom | PS I know these boards from ztex. I found them rather interesting too. | 18:56 |
| kristianpaul | btw mwalle you there? | 18:58 |
| kristianpaul | did you finally be able to ran uart core faster than current design? | 18:59 |
| kristianpaul | and take some advantage of the high speed usb ftdi chip from the jtag-serial pod :-) | 18:59 |
