[opensuse-arm] Emulate image for Raspberry Pi2 in QEMU
From looking around it appears one needs kernel, initrd and DTB separately. So I
Hello all, I'm trying to get an openSUSE image for Raspberry Pi2 going in QEMU. But everything I've tried so far didn't work. --> I'd greatly appreciate any hints or pointers where to perform an RTFM. I started at https://en.opensuse.org/HCL:Raspberry_Pi2 with this image openSUSE-Leap15.0-ARM-JeOS-raspberrypi2.armv7l-2018.07.02-Buildlp150.1.1.raw peeled them off the image and tried booting like this: --- snip --- INITRD=initrd-4.12.14-lp150.11-lpae KERNEL=zImage-4.12.14-lp150.11-lpae DTB=bcm2709-rpi-2-b.dtb HDDIMG=openSUSE-Leap15.0-ARM-JeOS-raspberrypi2.armv7l-2018.07.02-Buildlp150.1.1.raw qemu-system-arm \ -M raspi2 \ -kernel ${KERNEL} \ -initrd ${INITRD} \ -dtb ${DTB} \ -append "rw earlyprintk loglevel=8 console=ttyAMA0,115200 dwc_otg.lpm_enable=0 root=/dev/mmcblk0p2" \ -drive if=sd,format=raw,file=${HDDIMG} --- snap --- But this only gives a blank screen in the QEMU window (also on the serial console) and 100% CPU usage. I've tried a few variations but the symptoms stay the same. So how do I start one of the openSUSE images for Raspberry Pi2 in QEMU? Thanks and regards -- Till -- Dipl.-Inform.

FTR, I'm using QEMU 2.11.2. Does anyone know, whether this is actually supposed to work? Thanks and regards -- Till -- Dipl.-Inform.

Any reason to try the RPi2 image instead of an EFI image? I did not try to use RPi2 image on qemu, but you can use JeOS-efi image which works properly (I tested armv7 JeOS-efi image under qemu recently). Thanks, Guillaume

Yeah. An image to be deployed to an RPi2 is best prepared in a (virtual) environment as compatible as possible.
I did not try to use RPi2 image on qemu, but you can use JeOS-efi image which works properly (I tested armv7 JeOS-efi image under qemu recently).
I could easily boot the openSUSE AArch64 images for Tumbleweed and Leap 15.0 und QEMU. It's just that QEMU appears to also support the Raspberry Pi 2, so I wanted to get openSUSE going with that, too. Regards -- Till -- Dipl.-Inform.

Sure. You can use armv7 JeOS-efi (not aarch64) which is pretty close.

Why aarch64? Use armv7l version.

IIRC, the RPi2 support in qemu is quite limited, no graphical output, only serial. No support for boot from firmware as only the ARM cpu is emulated, not the GPU. So, you will need to extract kernel + initrd and pass rights options as kernel cmdline, as you are trying to do. Maybe adding '-nographic' option could help?

I tried that, but it didn't work. So I guess I won't pursue QEMU + RPi2-emulation any further but stick to JeOS-armvl instead. Thanks again -- Till -- Dipl.-Inform.
