How to emulate recalboxOS v4.0 using qemu?

[Txiki Diaspora]

Hi.

I'm trying to launch recalboxOS v4.0.0 using qemu-system-arm and it seems I'm doing something wrong.

After install qemu in Fedora 25:

sudo dnf install qemu

I downloaded recalbox v4 from here

Then, I try to create a valid iso using:

fallocate -l 1G recalbox_image.img                                     # Create img file
mkfs.msdos recalbox_image.img                                        # Set fat32 format
mkdir recalbox                                                                              # Create temporal folder
sudo mount -o loop recalbox_image.img ./recalbox    # Mount img in folder
sudo unzip recalboxOS-4.0.0.zip -d recalbox                  # Unzip recalbox 4 in img
genisoimage -o recalbox.iso recalbox                                # Create iso

After creating iso, I try to launch it using:

qemu-system-arm -machine raspi2 -hda recalbox_image.img -m 1024 # Launch nothing

It is probably a problem with missing kernel or something. I tried to download raspbian kernels to use them from:

git clone https://github.com/dhruvvyas90/qemu-rpi-kernel

But nothing:

qemu-system-arm -machine raspi2 -hda recalbox_image.img -m 1024 -kernel qemu-rpi-kernel/kernel-qemu-4.4.13-jessie -append "root=/dev/sda2" # Nothing happend

and using:

qemu-system-arm -M versatilepb -cpu arm1176 -hda recalbox_image.img -kernel qemu-rpi-kernel/kernel-qemu-4.4.13-jessie -m 1024 -append "root=/dev/sda2"

neither (any version). Someone know what kernel or configuration I must to use?

As far as i remember qemu id dreadly slow and hardly emulates a pi0 + iy can't handle the hdmi display, so i don't think you'll get anything with it

Hi, i have seen rasbpbian is emulated under windows here https://sourceforge.net/projects/rpiqemuwindows/
I would like to virtualize recalbox for testing purpose, someone have tried?

@0zzy recalbox is not a raspian. Besides emulators in emulator... Not usable at all

@0zzy haven't tried qemu for ages, but last time i tried it had horrible performance emulating a pi1 ... And I'm not sure it can run real video output. But you should go ahead and try, we dev don't have much time to test such things

hi all!
i was looking to emulate recalbox only to test roms quickly, because my raspy is far from my desktop, and because i'm a vcp, i like to virtualize all

@0zzy well, keep trying, i'd be curious to see how it works afterall
