Zynthian development in a (ARM) VM?

[C0d3man]

Hi @ll,

I just wondering if there is a possibility to create a “virtualbox” or “qemu” image which emulates a Raspi(3)/ARM for developing Zynthian images?

I googled and found some hints - but everything not really easy or outdated… does anyone has heard about that or can create such an environment?

Vagrant boxes for Zynthian development?

Hahahaha exactly. Gotta love Windiosyncrities. So I’m a huge fan of pyenv just for the record. Virtualenvwrapper never seemed to work exactly right for me. I guess my idea here is more around the HW itself. A lot of the Zynthian code is actually about building/managing the image that will be dumped onto your flash card. Things like disabling rpi-updates, which you’d want for your Zynthian machine. It’s hard to test that unless you have the environment (that is, a Pi), and there are other insta…

Hi @C0d3man,

I’ve found an interesting site explaining how to install raspberry qemu emulation over windows. I didn’t try to be honest but looks promising. Apparently, when install pocess is completed, you will get “pixel” desktop. What I wonder if it will be a way to emulate gpio, or a way to emulate soundcards (I don’t know whether or not you will need it).

Uncompressing Linux… done, booting the kernel.

And then it reboots, which means game over.
at home i will check, which kernel gorgona expects.

this was my last shattered dream:

qemu-system-arm -kernel ~/Downloads/kernel7.img -cpu arm1176 -M versatilepb -append “root=/dev/sda2 rootfstype=ext4” -hda /home/markus/Downloads/zynthian_gorgona_rbpi2-2016-12-22.img

I took the kernel7.img from the gorgona image.
But what I got is a black screen.

New versions of qemu-system-arm have -M raspi2…but not for ubuntu. Maybe a windows person could try.

This seems to be not easy.
