| ysionneau | Anyone interested in a M1R4 board? | 14:28 |
|---|---|---|
| ysionneau | if ~5 people are interested I might launch a kickstarter campaign | 14:29 |
| ysionneau | if if ~10 people ask for one, I think we could run a batch | 14:29 |
| ysionneau | hoping to achieve something like 700-800 EUR unit price | 14:30 |
| ysionneau | it seems 2 people are interested according to recent emails on the Mailing List | 14:30 |
| lekernel | ysionneau, 3 -> https://twitter.com/ramataupia/status/393401942007115776 | 14:31 |
| cde | ysionneau, I have a spare M1R4 I don't use. I can give it to you | 14:32 |
| lekernel | I wonder what happened to the remaining M1/Nanonote stock at Sharism ... | 14:32 |
| ysionneau | yeah ... | 14:33 |
| ysionneau | cde: I think there are people interested in buying such a board | 14:34 |
| ysionneau | you could sell it very easily | 14:34 |
| ysionneau | is it really a R4 ? :o I thought R4 never got manufactured | 14:35 |
| lekernel | don't give it away. it encourages drawerware. | 14:35 |
| cde | I'm quite unsure the exact revision. I bought it in august 2011 at the sharism store | 14:35 |
| ysionneau | must be R2 or R3 | 14:36 |
| ysionneau | cde: are you on the milkymist mailing list ? | 14:37 |
| cde | I used to be, but I canceled my gmail account | 14:38 |
| ysionneau | oh | 14:38 |
| cde | I can tell you the exact revision at home tonight | 14:38 |
| ysionneau | ok cool :) | 14:45 |
| ysionneau | cde < I asked about the ML because someone is asking about buying a M1 board :) | 14:45 |
| cde | oh | 14:47 |
| ysionneau | on this thread: https://ssl.serverraum.org/lists-archive/devel/2013-October/003464.html | 14:48 |
| wpwrak | r4 was never made and i think there may be about one or two r3.5 (r3 with some r4 rework) in the world. (i have one. not sure if adam made one for himself, too) | 15:21 |
| wpwrak | ysionneau: if you make new board, you may want to include at least the reset fix. else, you still have the NOR corruption problem. | 15:22 |
| ysionneau | that's why I mentioned M1R4 | 15:23 |
| ysionneau | on irc | 15:23 |
| ysionneau | sebastien told me about it | 15:23 |
| wpwrak | the whole m1r4 design has quite a lot of changes compared to m1r3. so it would be a little risky to try to make it. of course, it's better, too, and it has a lot of pretty LEDs ;-) | 15:26 |
| ysionneau | hum hum | 15:26 |
| ysionneau | I would only be interested in very minimum risk | 15:27 |
| wpwrak | ah, and as far as i know, wolfgang sold all or as good as all of his m1r3 stock | 15:27 |
| ysionneau | just doing what we already did | 15:27 |
| ysionneau | what we know works | 15:27 |
| ysionneau | so maybe just R3.5 (R3 with the NOR corruption fix) | 15:27 |
| wpwrak | that would be m1r3 with the reset fix and i think r3 also had those beads/inductors that forced ESD to go through chips, causing pretty crashes and hangs. (solution: just connect the ground planes under the respective chips, without a separating inductor/bead) | 15:29 |
| wpwrak | yes, and the beads (Lsomething) | 15:29 |
| ysionneau | ok we need to think a little bit about what to do exactly to minimize risk but implement fix we already know work | 15:31 |
| ysionneau | I will get back to you later :) | 15:31 |
| wpwrak | yeah, the fixes are pretty simple. if all else fails, you can even do them as rework. | 15:32 |
| lekernel | wpwrak, well at least the r4 flash fix made it into mixxeo (and I haven't seen any flash issue so far) | 16:03 |
| GitHub84 | [migen] sbourdeauducq pushed 1 new commit to master: http://git.io/UiO9_g | 16:54 |
| GitHub84 | migen/master 892c12b Sebastien Bourdeauducq: flow: add AbstractActor busy signals | 16:54 |
| ysionneau | 18:03 < lekernel> wpwrak, well at least the r4 flash fix made it into mixxeo (and I haven't seen any flash issue so far) < that's really good news :) | 19:03 |
| ysionneau | too tired to send anything this evening, I hope I will have some time tomorrow to send a sum up of what could be done for a possible new batch of M1 boards (if enough people interested) | 21:11 |
| ysionneau | gn8! | 21:11 |
