| cladamw | wpwrak, i'm considering let LINE_OUT connector to adjacent to LINE-IN con. together as U23 is within them which is not good for diagnosis. | 08:44 |
|---|---|---|
| isa | test | 10:33 |
| wpwrak | cladamw: hmm, let's see ... | 11:53 |
| wpwrak | commercially available dual 3.5 mm jacks have a center to center distance of 15 mm | 11:54 |
| wpwrak | like we do in M1rc3 | 11:54 |
| wpwrak | adam really needs a permanent internet connection ... | 11:56 |
| cladamwa | wpwrak, no, i have two laptops. ;-) In Windows I also installed an irc server, sorry | 11:58 |
| cladamwa | wpwrak, i prefer to use current two con. rather than finding a dual 3.5 jack | 11:59 |
| wpwrak | oh sure, two connectors is okay | 12:00 |
| cladamwa | wpwrak, or place parts in bottom side( which is not I want ). | 12:00 |
| wpwrak | i just looked for indications of what distances are used | 12:00 |
| cladamwa | i see | 12:00 |
| cladamwa | wpwrak, http://en.qi-hardware.com/wiki/File:M1r4_j1j2u23.png | 12:01 |
| cladamwa | since the case should already being not same as rc3. so i planned to like this. | 12:02 |
| wpwrak | if we consider that a user may want to connect 6.3 mm jacks, then at least about 15 mm center-to-center distance would be reasonable. a 6.3 mm jack has an outer diameter of about 13-14 mm | 12:06 |
| wpwrak | (6.3 mm jacks) via adapters, of course | 12:06 |
| cladamwa | hmm ... 6.3 mm jack seems a popular one for the musical instruments. I hope you are not serious on this, are you ? | 12:10 |
| wpwrak | semi-serious :) | 12:12 |
| wpwrak | i'm not entirely sure whether professional users would trust a 6.3 mm to 3.5 mm adapter | 12:12 |
| wpwrak | but i've seen a fair bit of 6.3 mm in higher end equipment. so i can very well imagine that someone out want to connect to that | 12:13 |
| wpwrak | and if the spacing is too tight, things get messy | 12:13 |
| wpwrak | looking at dual 3.5 mm stereo connectors ... they look a bit scary. quite tall (24.0-26.7 mm) and probably need a screw for stress relief | 12:15 |
| wpwrak | like this http://products.cui.com/GetSpecForDigiKey.aspx?MFGNum=SJD-3512-45 or this http://products.cui.com/GetSpecForDigiKey.aspx?MFGNum=SJD-3510-45 | 12:16 |
| cladamwa | wpwrak, yes, when i went to a swimming poor which they play music by huge speakers with 6.3 mm pluger, their instruments can set a lot audio effects and equalizers. | 12:16 |
| wpwrak | so that's probably not a viable alternative. both would have 15.0 mm center-to-center, though | 12:16 |
| cladamwa | the rear of intruments are all 6.3mm receiptacles. | 12:17 |
| cladamwa | wpwrak, yeah...the length can't be used in m1, too waste space. | 12:17 |
| wpwrak | how about moving U23 under the expansion board ? between J21 and U1 ? there seems to be a bit of free space | 12:19 |
| cladamwa | wpwrak, the expansion board can do such 6.3mm CD-in then use SPDIF-out. :-) | 12:20 |
| wpwrak | ;-)) | 12:20 |
| cladamwa | sure, why not. :) but i was just considering to free space under expansion area. Since who knows will build great extra-value-added for m1 though expansion. I know like you are ! | 12:23 |
| wpwrak | i'm not so much worried about free space in general but about the maximum height of the things under the expansion board. it seems that U23 wouldn't make a difference in this regard | 12:24 |
| cladamwa | so i meant if m1r4's case doesn't need to same as rc3 as dvi-i connector-variant there. | 12:25 |
| cladamwa | oah...yeah. the U23's height is not too tall, so if you prefer to place there, then we go there. :-) | 12:26 |
| wpwrak | yes, i'd rather have U23 under the expansion board than the two audio jacks very close to each other | 12:32 |
| wpwrak | even without 6.3 mm adapters, it's not very convenient to have very closely spaced connectors | 12:33 |
| wpwrak | (case) yeah. it'll be a new design. that much is certain :) | 12:33 |
| wpwrak | unless xiangfu wants to try his disc-cutting drill ;-) | 12:34 |
| cladamwa | wpwrak, like this. http://en.qi-hardware.com/wiki/File:M1r4_j1j2u23.png :-) | 12:35 |
| wpwrak | that's the same as before ? | 12:36 |
| cladamwa | updated. :-) alright, collecting feedbacks here: http://en.qi-hardware.com/wiki/Milkymist_One_R4_Layout_History | 12:37 |
| cladamwa | sorry that they are in Chinese. :) | 12:38 |
| wpwrak | yeah, the update looks good | 12:38 |
| wpwrak | (cn) ;-) | 12:39 |
| cladamwa | your internal usb (with atusb dongle) I'll add it. | 12:39 |
| cladamwa | wpwrak, another question, where we supposedly place those un-used LEDs ? | 12:45 |
| cladamwa | wpwrak, current TPs for LEDs-M are under bottom side. I'm thinking to place them to top side for easy. Is it okay to you ? | 12:46 |
| wpwrak | i don't have a place for them. what could be a little interesting is to have a few of them on the pcb edge, below the eastern edge of the expansion board | 12:47 |
| wpwrak | that way, they could be used to signals things there, if someone wants that | 12:48 |
| wpwrak | top side is fine with me | 12:49 |
| cladamwa | still have 8 un-used LEDs, so few of them to the eastern edge of expansion board, or all ? | 12:50 |
| wpwrak | your choice :) | 12:50 |
| cladamwa | (LEDs TPs on top) okay. tks. | 12:50 |
| cladamwa | phew... | 12:51 |
| cladamwa | (reserved leds) http://en.qi-hardware.com/wiki/File:M1r4_place_for_unused_leds.png | 12:56 |
| wpwrak | ah, and we can DNP the "reserved" LEDs anyway. i would place them in the prototype run, to check things, but then we can save wolfgang a few cents :) | 12:56 |
| wpwrak | nice :) | 12:56 |
| cladamwa | place them as the idea you gave, but we DNP them in m1r4. | 12:57 |
| wpwrak | but there's not enough room for all of them. at least not if we design for side-facing leds, which have their long side parallel to the pcb's edge | 12:57 |
| wpwrak | actually ... they may just fit :) | 12:58 |
| wpwrak | the green area is 60 mm on my screen and you can probably have one LED every 8 mm, so that would work | 12:58 |
| cladamwa | rough just for illustration for house, I'll tell them to centralize them. :-) | 13:01 |

| Fallenou | nice link kristianpaul :) | 20:26 |
| Fallenou | I finally got the MMU to work on the FPGA | 20:27 |
| Fallenou | I mean, to pass the 15 test cases without crashing the soc :) | 20:27 |
| Fallenou | Will commit very soon | 20:27 |
| kristianpaul | Fallenou: oh ! | 20:36 |
| kristianpaul | great | 20:36 |
| kristianpaul | what you did it to make it work= | 20:36 |
| kristianpaul | s/=/? | 20:36 |
| kristianpaul | sorry i havent read logs since sunday.. | 20:36 |
| Fallenou | I forgot to take into account some internal signaling of the pipeline | 20:38 |
| Fallenou | I am not totally sure that it's working 100% correctly, I only tested 15 different load/store configurations | 20:44 |
| Fallenou | I will add more tests with more instructions to stress test the pipeline a little bit | 20:44 |
| Fallenou | I tested all the instructions sequences of store (nop)* load (nop)* with 6 instructions (the pipeline size) | 20:46 |
| Fallenou | like store load nop nop nop nop , store nop load nop nop nop etc | 20:46 |
| Fallenou | And puuuush https://github.com/fallen/milkymist-mmu/compare/5b90cf4bb2...5cf64084e3 | 21:46 |
