| shorne | mithro: I am working on it :) I got my gdb and qemu patches done | 00:41 |
|---|---|---|
| shorne | Right now I am working on vivado (maybe not needed yet) but just need to get to it | 00:42 |
| mithro | shorne: awesome! I'll be around in like an hour for most of the afternoon | 00:42 |
| mithro | Vivado is needed for the Arty | 00:42 |
| shorne | I had a read through your google doc, I think I can complete that tonight | 00:43 |
| shorne | today there are a few family things to do, and all this week work | 00:43 |
| mithro | ISE is needed for MimasV2 | 00:43 |
| shorne | So goal, by tonight have it running in qemu | 00:43 |
| mithro | It should only take a few hours to get set up unless you hit issues | 00:44 |
| mithro | Qemu doesn't need ISE or Vivado | 00:45 |
| shorne | right, I noticed that there was no spartan-6 support in the vivado I downloaded | 00:45 |
| mithro | Yeah :-/ | 00:45 |
| shorne | which is a bit unfortunate after a 14gb download | 00:46 |
| mithro | The mimasv2 doesn't quite work yet | 00:46 |
| shorne | Yeah, but I figured I would blink and LED or something first to understand the workflow on these boards | 00:47 |
| mithro | At the moment the DDR controller needs the core to run at 83mhz and ISE has trouble routing things on the lx9 at that speed | 00:48 |
| mithro | Works fine at 50mhz but then the DDR isn't working correctly it seems.. | 00:49 |
| mithro | Need to chat with _florent_ about the fix for that | 00:49 |
| shorne | what is the lx9? | 00:50 |
| mithro | Spartan 6 LX9 - means it has about 9000 cells | 00:50 |
| shorne | maybe we need multi-clock domains with some cross clock domain fifos? | 00:51 |
| shorne | I see right I remember you saying that the higher clock rate doesnt route | 00:51 |
| mithro | The Opsis and Atlys have LX45 (45000 cells) | 00:51 |
| mithro | The Arty is an Artix-7 35T which means it has ~35,000 cells | 00:52 |
| shorne | I see, those numbers make sense then | 00:54 |
| shorne | 9,45,35 :) | 00:54 |
| mithro | They are generous in rounding up | 00:55 |
| mithro | And the Spartan 6 cells and a bit different to the Series 7 cells | 00:55 |
| mithro | S/and/are/ | 00:55 |
| shorne | well, I am getting started.. now family calling | 00:57 |
| mithro | But yeah, generally the Xilinx parts have the cell counts in the part name | 00:57 |
| mithro | No worries, have fun! | 00:57 |
| shorne | right, I never noticed any logic to the numbers on the altera parts | 00:57 |
| shorne | mithro: for the first part litex-firmware | 00:59 |
| shorne | I find these branches | 01:00 |
| shorne | remotes/origin/or1k-debug | 01:00 |
| shorne | remotes/origin/or1k-fixing | 01:00 |
| shorne | or1k-fixing being the latest | 01:00 |
| mithro | Spartan -> Artix -> Kintex -> Virtex -> Ultrascale | 01:00 |
| mithro | shorne: check my email about the Arty? | 01:01 |
| mithro | On my phone, so can't look easily | 01:02 |
| mithro | Will be at a computer in about 30 minutes | 01:03 |

| shorne_ | running download-env.sh | 07:29 |
| shorne_ | interesting, this really is a whole environment with python and everything | 07:30 |
| shorne_ | mithro: ok, for the first issue with fxload missing | 07:31 |
| mithro | shorne_: You most definitely want to update to what I pushed an hour or two ago... | 07:32 |
| mithro | shorne_: BTW - I'm hoping to merge that branch in the next couple of hours | 07:32 |
| shorne_ | mithro: | 07:33 |
| shorne_ | +echo | 07:33 |
| shorne_ | +echo "Installing fxload (tool for Cypress FX2)" | 07:33 |
| shorne_ | +# conda install fxload | 07:33 |
| shorne_ | check_exists fxload | 07:33 |
| shorne_ | why is "conda install fxload' commented out? | 07:33 |
| shorne_ | I updated to the latest | 07:34 |
| shorne_ | IM going to uncomment that and try again | 07:34 |
| shorne_ | I dont need cypress but might as well | 07:34 |
| mithro | shorne_: I think because we don't have a conda package for fxload yet.... | 07:34 |
| shorne_ | ah, Ill see, ill just comment out the check | 07:34 |
| shorne_ | I am assuming I dont need it for qemu firmware build | 07:35 |
| mithro | Nope | 07:35 |
| mithro | shorne_: ./scripts/download-env-root.sh <-- that installs fxload via apt-get | 07:36 |
| shorne_ | I see | 07:36 |
| shorne_ | Ill put a note in the docs on that | 07:36 |
| mithro | shorne_: Do you have edit access? | 07:37 |
| shorne_ | I can comment | 07:37 |
| shorne_ | ok, i need the ftdi lib/driver too ill run the root env thing... but I run Fedora :) | 07:40 |
| shorne_ | let me convert this to dnf | 07:41 |
| mithro | dnf? | 07:41 |
| mithro | That libftdi stuff should be fixed soon -- I think I have figure out how to make openocd statically link against libftdi and libusb | 07:41 |
| shorne_ | well, yum (they call it dnf in fedora now) | 07:41 |
| shorne_ | the package manager | 07:42 |
| shorne_ | apt-get equivalent | 07:42 |
| shorne_ | hmm, the ftdi stuff doesnt match fedora 'looking for libftdi.so.1', but fedora has libftdi1.so | 07:45 |
| shorne_ | let me see what it really needs | 07:45 |
| mithro | Oh, I think we had instructions for that somewhere.... | 07:45 |
| shorne_ | I am trying `sudo ln -s /usr/lib64/libftdi1.so /usr/lib64/libftdi.so.1` it seems to work | 07:55 |
| mithro | shorne_: You could actually do a "ln -s /usr/lib64/libftdi1.so build/conda/lib/libftdi.so.1" probably | 07:57 |
| shorne_ | ah, just into the local path | 08:05 |
| shorne_ | right, it seems to work either way | 08:05 |
| mithro | The environment tries very hard to get everyone *exactly* the same environment... | 08:06 |
| shorne_ | mithro: environment seems to be loaded | 08:10 |
| mithro | shorne_: Awesome! | 08:10 |
| shorne_ | running build-qemu | 08:10 |
| mithro | Hopefully that works - I haven't run it in the last couple of hours :-P | 08:12 |
| shorne_ | yeah. I guess running on fedora I am in a bit of a no mans land? | 08:12 |
| shorne_ | I should probably try to run this on docker | 08:13 |
| mithro | A bit, but once you have the enviroment it shouldn't be all that dependent on the outside environment | 08:13 |
| mithro | I guess qemu is possible the one case where it would be... | 08:13 |
| *** anant3110 has joined #timvideos | 08:14 | |
| anant3110 | Hi, I am just starting out and I love the work being done in your organisation specially the HDMI2USB project. I know basic to intermediate verilog programming, java, python and C++. Is there anyway I can contribute? | 08:19 |
| mithro | anant3110: Hello! | 08:19 |
| mithro | anant3110: There are plenty of things to contribute too, how much time do you have? :-P | 08:20 |
| anant3110 | I can give 7-12 hours per week. | 08:21 |
| mithro | anant3110: Cool, were in the world are you located? I'm guessing maybe India? | 08:22 |
| anant3110 | Yes! | 08:24 |
| mithro | anant3110: So, what part interests you more? You interested in doing more stuff running on hardware side of things - or more stuff running on the computer? | 08:25 |
| anant3110 | I would be much more interested in the hardware part as long as I get the resources easily. My institute does have a lot of FPGA models but I will have to check if your requirements match with them. If that doesn't work out, I would be okay to do stuff running on the computer. | 08:28 |
| mithro | anant3110: The boards you should look out for are "Digilent Arty" and "Digilent Atlys" | 08:32 |
| anant3110 | I m pretty sure I have seen a Digilent Atlys in my lab. But I m not sure about Arty. | 08:35 |
| mithro | shorne_: Hows that build going? | 08:36 |
| shorne_ | mithro: sorry, had to be away | 08:38 |
| mithro | anant3110: You can get the build environment setup before having hardware... | 08:38 |
| shorne_ | I got an error 'ERROR: configure test passed without -Werror but failed with -Werror.' ... | 08:39 |
| shorne_ | no time to loo kat right now | 08:39 |
| shorne_ | on my way out again | 08:39 |
| mithro | shorne_: Okay | 08:39 |
| shorne_ | (that was on qemu) | 08:42 |
| anant3110 | mithro: That would be cool. Can you give me a link to the code base? If not this : https://github.com/timvideos/HDMI2USB-litex-firmware | 08:45 |
| tpb | Title: GitHub - timvideos/HDMI2USB-litex-firmware: A version of the HDMI2USB firmware based around LiteX tools produced by @Enjoy-Digital (based on misoc+migen created by @M-Labs) (at github.com) | 08:45 |
| mithro | anant3110: Yes - that is the correct thing to start with, there should be a "getting-started.md" file in the repo | 08:46 |
| mithro | shorne_: Will test here | 08:46 |
| anant3110 | mithro: I ll get back to you once I m done! | 08:48 |

| jimmo | conda was more fun when we were on google's internet | 12:01 |
| jimmo | @mithro are you going to update scripts/download-env or should i? | 12:02 |
| mithro | jimmo: xxx-newlib seems to be only needed for Linux / MicroPython firmware -- not the bare metal ones | 12:03 |
| jimmo | what libc does hdmi2usb use? | 12:04 |

| jimmo | nope. unsupported SPI flash chip | 12:16 |
| mithro | Use the opsis target | 12:20 |

| jimmo | but your doc says it boots to login ? | 12:31 |

| mithro | jimmo: Are you using the base target or the net target? | 12:33 |
| jimmo | base | 12:33 |
| shorne_ | mithro: I fixed the qemu thing it was an issue with my CFLAGS | 12:34 |
| shorne_ | I deleted a path earlier today it cause a issue with qemu configure | 12:34 |
| mithro | Hey shorne_! | 12:34 |
| shorne_ | nothing related to litex | 12:34 |
| shorne_ | but.. my time is up today unfortunately | 12:35 |

| mithro | I think jimmo might have accidently stumbled on something interesting... | 12:35 |
| shorne_ | next will be linux tomorrow if I get time | 12:35 |
| jimmo | changing the irq got rid of the irq 0 error, but otherwise identical | 12:35 |

| shorne_ | gcc (GCC) 7.2.1 20170915 (Red Hat 7.2.1-2) | 12:43 |
| shorne_ | ah, maybe too new | 12:43 |
| jimmo | same as me | 12:43 |
| shorne_ | and qemu to old? | 12:43 |
| mithro | Yeah | 12:43 |
| shorne_ | ok, then ill look into it | 12:43 |
| mithro | I started rebasing and splitting each feature into their own branch | 12:43 |
| jimmo | or remove -Werror from configure:4752 | 12:43 |
| mithro | shorne_: For now you can just disable the -Werror | 12:43 |
| shorne_ | ok, I can do that too | 12:43 |

| mithro | shorne_: great! | 12:51 |
| shorne_ | mithro: cool, on splitting features out to branches, I was splitting all of the openrisc backlock out to feature branches | 12:52 |
| shorne_ | it made the work of upstreaming a bit more pragmatic | 12:52 |

| mithro | jimmo: So, you going to try get hardware Linux? | 12:57 |
| jimmo | @mithro - that's only possible on the arty? | 13:08 |
| jimmo | i'll have to install vivado then | 13:08 |
| mithro | jimmo: Or the Opsis - which you have two of | 13:08 |
| *** CarlFK has quit IRC | 13:13 | |
| jimmo | @mithro i'll leave vivado downloading and opsis gateware building | 13:20 |
| mithro | Opsis gateware should only take a couple of minutes | 13:20 |
| jimmo | @mithro the opsis has no programmer firmware right? because the fx2 gets its firmware as part of the programming process? | 13:37 |
| mithro | jimmo: More complicated than that - but you can think of it like that for now | 13:38 |
| jimmo | @mithro so i don't need to do anything on those two boards - i should just be able to gateware-load or gateware-flash? | 13:39 |
| mithro | Yeah | 13:40 |
| jimmo | cool ok i will try tomorrow | 13:40 |
