qemu FreeBSD MIPS Big Endian not booting in qemu

[bulkman]

Hi Forum,

i tried the last days to bring up a mips installation of freebsd in qemu. I went with different receipes, but none of them worked. I followed the steps here:
https://wiki.freebsd.org/QemuRecipes#mips

I also tried different archs like mips64, setting up an image with qemu-image and truncate, using MBR or GPT. I always fail at the stage mounting the rootfs and start init.

I setup a simple script building me an image:

#!/bin/sh
newroot="/mnt/ext_mips"
cd /usr/src
make TARGET_ARCH=mips buildworld
make TARGET_ARCH=mips buildkernel KERNCONF=MALTA
mkdir $newroot
make TARGET_ARCH=mips installworld DESTDIR=$newroot
make TARGET_ARCH=mips installkernel KERNCONF=MALTA DESTDIR=$newroot
make TARGET_ARCH=mips distribution DESTDIR=$newroot
etcupdate extract -B -D $newroot -s /usr/src -M "TARGET_ARCH=mips"

# creating things
makefs -M 4g -B be /root/newmips.img $newroot

I tried to start it with this and other commandlines:
qemu-system-mips -kernel malta_be.kernel -nographic -hda newmips.img -m 2048 -M malta -append "root=/dev/ada0" -boot c

Always ending up the same message, that the systems seem to have issues finding the root fs and drops into the debugger

1. Is someone aware of crucial mistakes i made?
2. Is MIPS support not available anymore?
3. Are there better tutorials i can follow to setup a freebsd mips instance?
4. Is there even a MIPS Installation setup?

Thank you

MIPS is a Tier 2 architecture.

MIPS is a Tier 2 architecture.

Ok. I understand that it is another architecture and i understand that not everything gets into MIPS. But i am not sure this should also answer my question about running it with qemu, is it?
