| cr1901_modern | mithro: Litex now expects you import migen as of a few days ago. Want me to take a shot at porting hdmi2usb/litex-buildenv to use a more recent litex? | 00:19 |
|---|---|---|
| cr1901_modern | It should be as simple as a sed expression, adding migen to conda builds, and then waiting 10 hours for the build | 00:19 |
| CarlFK[m] | cr1901_modern (IRC): im sure the answer is "yes" | 00:21 |
| cr1901_modern | CarlFK[m]: Okay, fair enough. If mithro says he doesn't want to upgrade, I'll blame you :) | 00:22 |

| CarlFK | shivm28: hmm.. I think you are close. my next guess: qemu thinks you are passing a disk image, and it is trying to boot from the boot sector, but the .bin is something else. | 19:18 |
| CarlFK | try -kernel bios.bin | 19:19 |
| CarlFK | I have no idea what format bios.bin is, but I am sure it isn't a disk image. | 19:19 |
| CarlFK | hopefully someone here who knows more about this can help better than I am | 19:20 |
| shivm28 | I will try to build QEMU for Raspberry Pi from their repo and then will come back to it. | 19:25 |
| shivm28 | Thanks a lot for the help. | 19:25 |
| CarlFK[m] | for Raspberry Pi ? | 19:26 |
| CarlFK[m] | I would look around the scripts and --help to see what --options are used. | 19:27 |
| shivm28 | I mean using this website: https://www.qemu.org/ | 19:28 |
| tpb | Title: QEMU (at www.qemu.org) | 19:28 |
| CarlFK[m] | that won't help much with this project | 19:29 |
| shivm28 | Oh ok. | 19:30 |
| shivm28 | This is an example for invokation from the documentation:qemu-system-i386 linux.img | 19:30 |
| shivm28 | Can I know what is the need of an image file? | 19:31 |
| shivm28 | Section 2.3 on this page: https://qemu.weilnetz.de/doc/qemu-doc.html#sec_005finvocation | 19:31 |
| tpb | Title: QEMU version 2.10.50 User Documentation (at qemu.weilnetz.de) | 19:31 |
| CarlFK | I don't really know any useful details | 19:33 |
| CarlFK | I mostly understand a disk image file and how that works. but I am very sure that doesnt help | 19:33 |
| CarlFK | I also know a bit about pxe booting, which also dosn't help | 19:34 |
| CarlFK | and a bit about running elf binaries, and bash shell scripts and python commands in the python vm. more things that don't help. | 19:34 |
| shivm28 | I think image file is for running that particular operating system on the arm core of the fpga | 19:37 |
| CarlFK | that sounds about right - but not sure it is "arm" ? | 19:38 |
| shivm28 | Do we need Linux or any other operating system on the fpga for this project?? | 19:40 |
| CarlFK[m] | yes and no. currently no and it works pretty well. | 19:41 |
| CarlFK[m] | but it would be better if it was running under linux - then we could use the linux network stack to work with the eathernet port (I think) | 19:42 |
| CarlFK[m] | 3 years ago we didn't even have a cpu - it was all just Verilog - it kinda worked, but not very well and was hard to debug/maintain | 19:43 |
| shivm28 | Wow. So much progress in such a short span of time. | 19:45 |
| shivm28 | I think running Linux on board is also one of the projects | 19:48 |
| CarlFK[m] | yes | 19:49 |
| CarlFK[m] | but it isn't needed today | 19:50 |

| cr1901_modern | Litex is starting to match migen behavior now, right? | 23:47 |
| cr1901_modern | Migen's behavior to extract the Xilinx build directory is to search for version numbers in the supplied toolchain_path directory. | 23:47 |
| cr1901_modern | If it doesn't find a version number, it will bomb: https://github.com/m-labs/migen/blob/master/migen/build/tools.py#L36 | 23:47 |

| cr1901_modern | Meaning now that litex mirrors migen behavior, it's not possible to use a single directory to point to both toolchains | 23:49 |
| cr1901_modern | mithro _florent_: What should be done about this? litex-buildenv relies on both ISE and Vivado being accessible from the same directory: https://github.com/timvideos/litex-buildenv/blob/master/scripts/download-env.sh#L107 | 23:55 |
