oh no.. this looks new:

(LX P=arty C=or1k.linux F=linux) juser@gator:~/tv/litex-buildenv$ ./scripts/build-qemu.sh

litex-buildenv/third_party/qemu-litex/util/memfd.c:40:12: error: static declaration of ‘memfd_create’ follows non-static declaration

or maybe this is old

shorne: are you around to look at qemu-system-or1k not booting linux?

shorne: it does boot hdm2usb

Title: Ubuntu Pastebin (at paste.ubuntu.com)

CarlFK: FYI (in response to earlier question), FuPy (MicroPython) won't currently build on or1k (only lm32). See https://github.com/fupy/micropython/issues/3 for more detail (and my attempt to date at https://github.com/fupy/micropython/pull/50, which doesn't work)

Title: Make FuPy MicroPython arch independent · Issue #3 · fupy/micropython · GitHub (at github.com)

CarlFK: Feel free to take a look at issues. I won't have time until (at least) next month to even get FPGA dev stuff out...

ewen: thanks - I'm trying to collect things that work into maybe a CI like test suite so we can see when things break sooner

(IIRC Linux is built on or1k basically because there's a Linux or1k port, but not a lm32 port; other things are most tested on lm32.)

CarlFK: CI test suite (expansion) is aogod plan

(a good) plan

http://paste.ubuntu.com/p/dzfyM43TcW/ cp's xilinx Vavado from a usb disk, clones repos and gets me to an hdmi2usb prompt runinng in qemu, then compiles linux for or1k, tries to boot that in qemu, and fails

cr1901_modern: This is on an lm32?

CarlFK: Looks like a good start. I think if you set CPU=lm32 and FIRMWARE=micropython you'd be able to run scripts/build-micropython.sh as well (although it'll probably need to download *another* cross compiler the first time its run)

CarlFK: I'm not aware of any attempt to get MicroPython (on lm32/or1k) running under qemu. But it might be useful to do at some point (and or1k may be easiest)

ewen: I don't have the time or skills right now to take that on

CarlFK: The "set environment variables and run scripts/build-micropython.sh" should in theory "just work".

CarlFK: The "MicroPython or1k build" is definitely a project for someone (else) in the future....

cr1901_modern: I'm curious how it works. Does your platform have its own custom "common.h" that previously defined MMPTR()?

hey

I am trying to set up litex-buildenv

based on this guide - https://github.com/timvideos/litex-buildenv/wik...

Title: HowTo LCA2018 FPGA Miniconf · timvideos/litex-buildenv Wiki · GitHub (at github.com)

I am using ubuntu 16.04

Title: built gateware, no image-gateware+bios+firmware.bin - Pastebin.com (at pastebin.com)

It looked like the build succeeded, and it top.bin was written, but a different file is documented as expected

mithro / CarlFK what do?

also, see you Saturday :)

Toba: hold...

Toba: this is a cop out - bu t this scrip runs for me

Title: Ubuntu Pastebin (at paste.ubuntu.com)

it is the commands from the HowTo

Toba: 16.04 should work too. unless we broke it making tings work with 18, wich is pretty likely

Toba: sorry, got distracted - where you at?

what? qemu-system-or1k: -M litex: unsupported machine type

Title: Ubuntu Pastebin (at paste.ubuntu.com)

good news: runing the same commands on debian gets the exact same results , including the fail

CarlFK: Just to be clear: the failure you're seeing is "unsupported machine type" and not "csr_writel(): undefined function", right?

xobs: no, that seemed to fix itself ;/

Title: Ubuntu Pastebin (at paste.ubuntu.com)

on qemu: litex boots, linux does not (I think that is accurate description)
