Bad register offset

[Bahir]

That's what I receive when running

bash-5.0$ sh -x run.sh qemu-system-arm -M versatilepb -cpu arm1176 -m 256 -drive file=./2018-11-13-raspbian-stretch-lite.img,index=0,media=disk,format=raw -net nic -net user,hostfwd=tcp::5022-:22 -dtb ./versatile-pb.dtb -kernel ./kernel-qemu-4.14.79-stretch -append 'root=/dev/sda2 panic=1' -no-reboot

vpb_sic_write: Bad register offset 0x2c

I fixed this by adding -serial stdio to my command.

@Bahir : Does the latest comment solve your problem ?

I'm getting the same error, running the following:

qemu-system-arm \
	-append "root=/dev/sda2 panic=1 rootfstype=ext4 rw" \
	-boot c \
	-cpu arm1176 \
	-drive "file=2019-04-08-raspbian-stretch-lite.img,if=scsi,cache=none,discard=ignore,format=raw" \
	-kernel ./kernel-qemu-stretch \
	-dtb ./versatile-pb.dtb \
	-m 256M \
	-machine type=versatilepb,accel=tcg \
	-name packer-qemu \
	-no-reboot \
	-vnc 127.0.0.1:4 \
	-nic user,id=user.0,hostfwd=tcp::5555-:22

Adding -serial stdio doesn't make the error go away for me, it just appends more lines after this error (as expected by the nature of the flag?).

This is on QEMU 3.1.0 (installed via Homebrew to MacOS 10.14.4)

I see same error with and without -serial stdio flag on Qemu 4.0.0 and Qemu 2.12.1

fwiw I see the message vpb_sic_write: Bad register offset 0x2c with and without -serial stdio , however redirecting serial to stdio does give me a working booted raspbian system (the message appears to be benign).

to block any ctrl+c action and opening the window, -display none -serial mon:stdio worked best for me

[vickiegpt]

for my case, I did it with:

qemu-system-aarch64 -M versatilepb \
                    -cpu arm1176 -hda 2019-09-26-raspbian-buster-full.img \
                    -net nic -net user,hostfwd=tcp::5022-:22 \ 
                    -dtb qemu-rpi-kernel/versatile-pb.dtb \
                    -kernel qemu-rpi-kernel/kernel-qemu-4.19.50-buster \
                    -m 256 -append "root=/dev/sda2" \
                    -no-reboot -serial stdio

Getting this error as well. Using -serial stdio does not appear to affect situation. Found source code reference to versatilepb.c showing value 0x2c not listed in switch statement. My guess is change in function signature or mis-ordering of arguments but I could be wrong.

                    -cpu arm1176 -hda 2019-09-26-raspbian-buster-full.img \

                    -m 256 -append "root=/dev/sda2" \
                    -no-reboot -serial stdio

I approved ... 💯

Here is my qemu detals and I'm using "Ubuntu 18.04".

$ qemu-system-arm --version

Adding -serial stdio fix the problem for me. I'm using "2022-04-04-raspios-bullseye-armhf-lite.img". So the command would be like this for me:

qemu-system-arm   -M versatilepb   -cpu arm1176   -m 256   -drive "file=./2022-04-04-raspios-bullseye-armhf-lite.img,if=none,index=0,media=disk,format=raw,id=disk0"   -device "virtio-blk-pci,drive=disk0,disable-modern=on,disable-legacy=off"   -net "user,hostfwd=tcp::5022-:22"   -dtb ./versatile-pb-bullseye-5.10.63.dtb   -kernel ./kernel-qemu-5.10.63-bullseye   -append 'root=/dev/vda2 panic=1'   -no-reboot -serial stdio
