| programmerjake | I reconverted the gfbinv code, since I think the way I have it with matching variable names will be easier to match to the original algorithm in the pdf. also, I changed the loop to just be: | 04:26 |
|---|---|---|
| programmerjake | for _ in range(m * 2) | 04:27 |
| programmerjake | since the idea is you loop a certain number of times, imho that's waay simpler than range(1, m * 2 + 1) | 04:27 |
| programmerjake | (I got m * 2 + 1 iterations by mistake while reconverting, fortunately, all the new tests (yay!) caught that mistake) | 04:30 |
| *** kylel1 is now known as kylel | 05:01 | |
| *** alMalsamo is now known as lumberjack123 | 14:26 | |
| lkcl | that's a good idea. it still looks really clear | 14:56 |
| tplaten | I programmed the OrangeCrab using JTAG: programming.. 5171488/5171488 \n verify.. 5171488/5171488 VERIFY OK | 16:38 |
| lkcl | tplaten, intriguing, following the online instructions from codeconstruct? | 17:10 |
| lkcl | (ecppack, ecpflash etc.) | 17:10 |
| tplaten | ecprog from https://github.com/gregdavill/ecpprog, installed today | 17:20 |
| tplaten | it works: Linux buildroot 5.16.0-rc1-13398-gdae78cf662a6 #1 Tue Mar 15 18:47:15 CET 2022 ppc64le GNU/Linux | 17:38 |
| lkcl | fantastic! | 17:39 |
| lkcl | programmerjake, i just realised, it's going to be really important to grab 2 of these whilst they're available | 17:40 |
| lkcl | https://1bitsquared.de/products/orangecrab | 17:40 |
| lkcl | tplaten would it be ok if jacob sent 2 more of those to you? | 17:41 |
| lkcl | tplaten, do you have a BTC address? | 17:41 |
| lkcl | so we can get cesar one of those orangecrabs? | 17:42 |
| programmerjake | tplaten: btc or some other cryptocurrency supported by coinbase | 17:48 |
| tplaten | I do not have a btc address, but I have a wise.com account. I have payed using JPY, USD and CZK. | 18:05 |
| tplaten | I inserted a microsd-card, but It failed with litex-mmc c8042800.litex-mmc: Command (cmd 8) failed, status 2 | 18:07 |
| lkcl | another way would be, if jacob you send tplaten enough through wise.com to cover 2x orangecrabs and the shipping to cesar (brazil) | 18:09 |
| programmerjake | i can send it via wise. lkcl, is there some reason we aren't sending money to cesar directly for him to order one himself? | 18:09 |
| lkcl | the US store is out of stock which is why i am going "eek, get them before..." | 18:09 |
| lkcl | programmerjake, yes, because the EU store refuses to ship outside of the EU | 18:09 |
| lkcl | and tplaten is in germany | 18:09 |
| programmerjake | ah, ok | 18:10 |
| programmerjake | tplaten let me know how much you need... | 18:10 |
| lkcl | tplaten, i'm astounded it even detected the card! :) | 18:11 |
| tplaten | Yes, I'm in Hesse, Germany and my brother is in Australia. | 18:11 |
| lkcl | that may be down to the type of the card, some might work, some might not (ultra-fast or not-ultra-fast) | 18:11 |
| tplaten | I'll have a look at the eu store | 18:13 |
| lkcl | https://1bitsquared.de/products/orangecrab | 18:14 |
| lkcl | we need the 85K ones | 18:14 |
| programmerjake | they call them orangecrab 85f iirc | 18:14 |
| lkcl | so it's 2x EUR 178 plus VAT times 2 call it EUR 450 | 18:14 |
| lkcl | programmerjake, wise don't charge a fortune, do they, in transfer fees? | 18:15 |
| programmerjake | iirc if i'm sending usd they charge like $0.30 though that was to canada, not germany | 18:16 |
| lkcl | if you sent him e.g. EUR 550 and we work out the cost to brazil by DHL, later? or, is that easy to get an estimate, tplaten, from DHL's website? | 18:16 |
| lkcl | ok | 18:16 |
| programmerjake | tplaten do you want eur instead? | 18:17 |
| tplaten | I had a look at https://1bitsquared.de/products/orangecrab, yes I want eur | 18:19 |
| programmerjake | also...it might be cheaper to send via a different shipper than dhl | 18:19 |
| tplaten | I ll have a look at DHL's website soon. | 18:19 |
| programmerjake | once you figure out how much you need, can you email me? thx. | 18:20 |
| tplaten | Yes, I'll do | 18:21 |
| tplaten | If I unserstand erverything correctly, one orangecrab goes to the us, the other one to brazil. | 18:22 |
| programmerjake | uuh...i already have one... | 18:23 |
| programmerjake | lkcl who needed the other one? or is it just a spare? | 18:24 |
| tplaten | so the second one is for ... one is for cesar, or both for cesar? | 18:25 |
| lkcl | one for cesar, one spare | 18:26 |
| lkcl | if someone else wants one and there's none in stock we're hosed | 18:26 |
| programmerjake | so the spare one i guess you can keep for now tplaten | 18:27 |
| programmerjake | unless someone wanted to build a libre-soc cluster? | 18:28 |
| tplaten | I have been thinking about buying an ECP5 board with an HDMI output, then connecting a HTC Vive, | 18:30 |
| tplaten | The Vive is using an ICE40 for their lighthouse tracking system. | 18:30 |
| cesar | I wonder if they ship directly to Brazil... You may have to receive it and then send it to me, maybe. | 18:37 |
| cesar | Otherwise I could order it myself, yes. | 18:37 |
| lkcl | cesar, no they are not | 18:37 |
| lkcl | i already encountered this with the EU site, i had to ask tplaten to receive them, they would not even ship to the UK | 18:37 |
| cesar | Well, at least the countries are listed in the shipping address form... | 18:41 |
| cesar | ... but it can give an error later, of course. | 19:04 |
| lkcl | yes, that's exactly what happened. | 19:37 |
| cesar | If programmerjake has the funds, can't he order himself, giving tplaten's shipping address, maybe? | 19:58 |
| programmerjake | hmm, i can try if you like... | 20:01 |
| programmerjake | tplaten would probably want to still buy the shipping himself...maybe? | 20:02 |
| octavius | lkcl, what about farnell?: https://uk.farnell.com/hackster-launch/orangecrab-r0d2-85/dev-board-ecp5-85f-512-mib-fpga/dp/3651572 | 20:15 |
| octavius | I guess the farnell is a bit more expensive (in GBP as opposed to EUR) | 20:15 |
| lkcl | octavius, good find! | 20:17 |
| lkcl | octavius, if you want one do say so, programmerjake could you send some GBP to octavius? | 20:19 |
| lkcl | btw i am grabbing some of the (large) HyperRAM modules from 1bitsquared as well | 20:19 |
| lkcl | i need to move on quickly, way behind on schedule, because of focussing on DDR3 for too long | 20:19 |
| cesar | Which was the suitable Ethernet PHY module again? | 20:29 |
| octavius | Sure, I'll have one. Will come in handy later for testing | 20:30 |
| octavius | I've been eyeing those versa boards for a few years now XD | 20:31 |
| cesar | Maybe it was this one? | 20:35 |
| cesar | https://www.waveshare.com/lan8720-eth-board.htm | 20:35 |
| lkcl | https://www.youtube.com/watch?v=0H4LTOYpAM4 | 21:20 |
| lkcl | cesar, yes that was one of them. they have another | 21:21 |
| octavius | I seem to remember that Realtek RTL8211F is what we were planning, no? | 21:21 |
| octavius | That's one of the datasheets on the ftp server | 21:21 |
| lkcl | https://libre-soc.org/shakti/m_class/RGMII/ | 21:21 |
| lkcl | https://www.waveshare.com/dp83848-ethernet-board.htm | 21:21 |
| lkcl | cesar, that's the other one | 21:21 |
| lkcl | that's an RGMII (125 mhz clock, Gigabit) | 21:22 |
| lkcl | 10/100 ethernet is driven by the clock coming from the MAC (IC) | 21:22 |
| lkcl | on *both* transmit *and* receive | 21:23 |
| lkcl | whereas RGMII you have to *provide* a transmit clock | 21:23 |
| lkcl | or | 21:23 |
| lkcl | create-some-sort-of-stabilised-variant-of-the-incoming-RX-125mhz-clock-and-use-that-for-Tx-as-well | 21:23 |
| lkcl | both of which are "blech" | 21:23 |
