| lkcl | cesar, a nmigen-boards platform file is needed, copied from migen and adapted. | 10:17 |
|---|---|---|
| lkcl | then the simple blinky can be done. | 10:17 |
| lkcl | without blinky working first it is just not possible to even do anything. | 10:18 |
| cesar | I'll try a Verilog blinky, first, to see that nextpnr-xilinx is really working for the Nexys Video. | 10:23 |
| *** markos <markos!~Konstanti@static062038151250.dsl.hol.gr> has joined #libre-soc | 10:27 | |
| lkcl | without a platform file (the pin-definition) you will not even be able to do that. | 10:28 |
| lkcl | nmigen-boards auto-generates the pin-definition file | 10:28 |
| lkcl | you could hand-create a pin-definition file | 10:28 |
| lkcl | and no, nextpnr-xilinx does not "work" for the xc7200t because it needs adding to grab the database file | 10:28 |
| lkcl | https://git.libre-soc.org/?p=dev-env-setup.git;a=blob;f=nextpnr-xilinx-install;h=ee250185675cbba75e1108b3b1962bca4e073b7a;hb=01851a3f83d9df6b4d4a366286d348da60495532#l88 | 10:29 |
| lkcl | line 86 | 10:29 |
| lkcl | bbasm on xc7200t has to be added | 10:29 |
| lkcl | you can start by compiling the blinky example for the art7-a7-100t | 10:29 |
| lkcl | but just not upload it | 10:29 |
| lkcl | then look in the build/ directory | 10:30 |
| lkcl | and hand-modify the results (and command-scripts) particularly the pin-definition file | 10:30 |
| lkcl | to match the nexys-video | 10:30 |
| lkcl | that's the short-cuts i'd take | 10:31 |
| lkcl | should be very quick | 10:31 |

| sadoon[m] | <lkcl> "ok i'm travelling again" <- Fun? :) | 11:10 |
| sadoon[m] | I was reminded of what you said yesterday re: nvme drives | 11:12 |
| sadoon[m] | My i7 1260p laptop (4P+8E cores) built all of my packages in gentoo on -j10 much faster than my Talos at -j72 | 11:12 |
| sadoon[m] | The actual compilation is slower, but because the drive is so fast all the other stages were much faster | 11:12 |
| sadoon[m] | I should start using tmpfs since I have more than enough RAM to do so :) | 11:12 |
| sadoon[m] | Unfortunately while nvme drives are getting cheap(er) it's not possible to install one on my Talos unless I need only one single drive, I absolutely need 8 SATA drives for easy hotswapping | 11:13 |
| sadoon[m] | Only 2 PCIe slots, one for GPU and one for SATA | 11:14 |
| markos | ah, because you have a single cpu installed? | 11:16 |
| sadoon[m] | That and it's a Talos Lite which has the second socket ripped off | 11:20 |
| sadoon[m] | But sells for much cheaper | 11:20 |
| sadoon[m] | (Cheaper) | 11:20 |
| sadoon[m] | Relatively speaking heh | 11:21 |
| sadoon[m] | tmpfs works though :) | 11:21 |

| programmerjake | you can get pciex16 cards that split out to 4 nvme drives (the cheaper ones require the cpu to be able to run it as 4x pciex4, idk if power9 supports that) | 20:51 |
| programmerjake | the cheaper ones should be quite cheap since they're basically just wires on a pcb and 4 nvme sockets | 20:54 |
| programmerjake | the more expensive ones should have a pcie switch chip | 20:55 |
| markos | just got myself an Amfeltec Squid PCIe 4x NVME pci card myself, this one is with a pcie switch chip | 21:00 |
| markos | haven't installed it yet | 21:00 |
| sadoon[m] | <programmerjake> "you can get pciex16 cards that..." <- I've tried an Asus one which didn't work and basically gave up | 21:07 |
| sadoon[m] | Might attempt in the future if I can find them cheap so it's not a gamble | 21:07 |
| programmerjake | then you probably need the pcie switch cuz that sounds like power9 doesn't support 4x pciex4 mode | 21:08 |
| sadoon[m] | Yeah | 21:09 |
| sadoon[m] | Currently attempting to get webengine to work well | 21:10 |
| sadoon[m] | It was working fine for a while and then it just wasn't.. Very weird | 21:10 |

| sadoon[m] | It feels futile since qtwebengine 6 is coming out but ughh | 21:13 |
| sadoon[m] | I'll take a few attempts what the heck | 21:14 |
| markos | power9 can actually support bifurcation, but only up to 3x with the asus, however, the firmware has to be modified, that's why I gave up myself as well and got the pci-e switch version | 21:15 |
| markos | the talos II rather | 21:16 |
| sadoon[m] | Can you point me towards one that has a pcie switch? | 21:16 |
| sadoon[m] | I might be able to Frankenstein a SAS to SATA pcie device as well as nvme drives then | 21:16 |
| sadoon[m] | Or hell at least a few nvme drives so it's not just the one | 21:17 |
| markos | https://www.ebay.com/itm/304716782887 <- 2x nvme, https://www.ebay.com/itm/175603314678 <- 4x nvme | 21:17 |
| markos | I got the 4x one | 21:17 |
| markos | haven't tested it first, but I don't expect any problems to be honest | 21:18 |
| sadoon[m] | Heh that's expensive damn | 21:18 |
| sadoon[m] | Anyways it's midnight and I'm about to pull my hair out thanks to webengine, I'll take some rest :') | 21:19 |
| sadoon[m] | I can't figure out why it stopped working.. | 21:19 |
| markos | we do have a meeting if you're interested, in case you've forgotten | 21:19 |
| sadoon[m] | I was playing youtube videos even so I'm 100% sure javascript was working too | 21:19 |
| sadoon[m] | What time? | 21:19 |
| markos | right now | 21:19 |
| markos | don't you get the reminder? | 21:19 |
| sadoon[m] | Alright since I'm awake.. | 21:20 |
| sadoon[m] | Not for this one because it starts at 12am for me :) | 21:20 |
