| CarlFK[m] | Kamilion (IRC): URL of your ebay store or better URL of the 20g ssd things | 01:53 |
| mithro | 20g SSD things? | 01:53 |

| Kamilion | 'make offer' button | 01:54 |
| CarlFK[m] | thanks | 01:55 |
| Kamilion | mithro: used mSATA SSDs on tyan brand SATA carriers | 01:56 |
| CarlFK[m] | drops the time to build a box from 20-30 min down to under 5 min | 01:57 |

| Kamilion | CarlFK[m]: double sided sticky tape is your friend. https://photos.app.goo.gl/AO9J39uFhljdNRsE3 | 01:57 |
| Kamilion | ask about 'empty' carrier adapters too, we've got so many I'm sure a deal can be hatched | 01:58 |
| Kamilion | that image shows a 250GB micron mSATA drive I picked up off amazon for $59 installed in the carrier. | 01:59 |
| CarlFK[m] | nice. | 02:01 |
| Kamilion | https://photos.app.goo.gl/nOCc0ntyxgI11WzN2 | 02:01 |
| Kamilion | this one i got for my dad | 02:01 |

| Kamilion | 8 brassy things? | 02:02 |
| Kamilion | ... uhhh... I dunno | 02:03 |
| Kamilion | There shouldn't be any RF sheilds in that | 02:03 |

| * Kamilion points to the right of the copper cooler | 02:04 | |
| Kamilion | they're supposed to be for these 1U server chassis. | 02:05 |
| CarlFK[m] | yeah, that | 02:05 |
| Kamilion | but we've scrapped all of that line of machines; and the only thing that remains is their mSATA carriers now... lol | 02:05 |
| Kamilion | they'd probably sell you about 25 of 'em for $2.50 each, without the SSD | 02:07 |
| CarlFK[m] | the mb had a place to plug them in? | 02:07 |
| Kamilion | two actually | 02:07 |
| Kamilion | but the adapter covers over the second one | 02:07 |
| Kamilion | *shrug* | 02:07 |
| CarlFK[m] | huh. the gender is backwards... | 02:07 |
| Kamilion | yes, the motherboard has the female connector, can actually stick any 2.5" SSD on it | 02:08 |
| CarlFK[m] | I bought a $50 lenovo Twist laptop .. "no screen or hard drive" | 02:09 |

| Kamilion | https://content.hwigroup.net/images/products_xl/266760/3/samsung-850-evo-250gb.jpg | 02:09 |
| CarlFK[m] | lenovo Twist all came with ssd and optional spinny disk | 02:09 |
| CarlFK[m] | so I was expecting an ssd and a keyboard | 02:09 |
| CarlFK[m] | the ssd was gone. | 02:09 |
| CarlFK[m] | im trying to figure out how much to fight for it. | 02:10 |
| CarlFK[m] | im sure it is an honest mistake and I should just let it go | 02:10 |
| CarlFK[m] | I was thinking of telling him to buy an ssd from you but the $15 shipping kinda messes that deal | 02:10 |
| Kamilion | any time you see a large shipping fee; that's generally to cater to europeans; who pay VAT on the price, but not the shipping. | 02:11 |
| Kamilion | so a lot of vendors cheat by 'discounting' the product and doubling the handling charge | 02:11 |
| Kamilion | not uncommon to see $99 shipping for an item marked $30 that should be closer to $90 | 02:13 |
| Kamilion | don't think that applies in this situation; but just wanted to explain that if you ever wondered WTF was going on with crazy shipping prices | 02:13 |
| CarlFK[m] | neat | 02:16 |
| CarlFK[m] | I can also see that the labor of dealing with inventory and shipping things isn't free, so may as well make a few bucks on that process too | 02:18 |
| Kamilion | well, ebay, in specific, lets you assign two fields separate, shipping, and handling, and combines them to show the customer. | 02:19 |
| Kamilion | if you tell ebay you're using a supported carrier, and provide weights and dimensions; ebay will use the customer's zip/postal code to automatically calculate shipping. | 02:20 |
| Kamilion | so what you see is what you get, re: final payment | 02:20 |
| Kamilion | instead of, say, calculating or recalculating shipping costs during the checkout process | 02:21 |
| Kamilion | and suddenly now you're paying $8 less in shipping, or demands $12 more for your postal zone... ETC | 02:22 |
| Kamilion | definitely one of the more well thought out things about ebay/buyitnow-clones such as aliexpress, dealextreme, and other aggregators | 02:23 |
| CarlFK[m] | yeah - and you can sort on total cost too. love that. | 02:30 |

| felix_ | _florent_: it seems that the a7 ddr3 phy doesn't work on the ac701, since write leveling isn't implemented yet and the sodimm on the board needs that due to the fly-by topology | 07:29 |
| felix_ | the best setting i tried still had Memtest bus failed: 45/256 errors | 07:30 |
| *** rohitksingh_work has quit IRC | 08:16 | |
| _florent_ | felix_: on artix7, we don't have odelay, so it's not possible to do write leveling the way we are doing it on kintex7, we are then just shifting the dqs_clk | 08:25 |
| _florent_ | felix_: if you want to find timing for the ddr3, there are scripts for that: | 08:26 |
| _florent_ | felix_: first create a design similar to this one for the ac701: https://github.com/enjoy-digital/arty-soc/blob/master/arty_ddr3.py | 08:26 |
| tpb | Title: arty-soc/arty_ddr3.py at master · enjoy-digital/arty-soc · GitHub (at github.com) | 08:26 |
| _florent_ | felix_: it's important to keep l2_cache to the minimum | 08:27 |
| _florent_ | felix_: then you can use this script to find all working bitslip/delay: https://github.com/enjoy-digital/arty-soc/blob/master/test/test_sdram.py | 08:28 |
| tpb | Title: arty-soc/test_sdram.py at master · enjoy-digital/arty-soc · GitHub (at github.com) | 08:28 |
| _florent_ | felix_: now if the script is not able to find a working configuration, you can play with the phase here: | 08:29 |
| _florent_ | felix_: https://github.com/enjoy-digital/arty-soc/blob/master/arty_base.py#L74 | 08:30 |
| tpb | Title: arty-soc/arty_base.py at master · enjoy-digital/arty-soc · GitHub (at github.com) | 08:30 |
| _florent_ | felix_: or since the ac701 has 8 ddr3 modules, you can try to reduce it to 2 modules first (for that just keep the first 16 dq, 2 first dm/dqs_p/dqs_n) and once working, increase the number of modules | 08:32 |
| *** futarisIRCcloud has quit IRC | 08:44 | |

| cr1901_modern | _florent_: Taking a quick glance over your litesdcard repo. How do you guarantee that the correct data will be sent to the SD card clock domain with MultiReg alone? | 09:48 |
| cr1901_modern | AIUI, MultiReg isn't enough to xfer multiple bits to another domain unless its gray-encoded | 09:49 |

| _florent_ | felix_: l2_size should not be 0, but the minimal value that allow compilation | 15:20 |
