qt-embdded-qemu_arm_versatile-buildroot-with-buildroot

configuration for buildroot to use qt creator on virtual qemu using qemu_arm_versatile

*execute the following

#mkdir qemu_arm_versatile_qt

#cd qemu_arm_versatile_qt

#git clone https://github.com/ibrahimmadnan/qt-embdded-qemu_arm_versatile-buildroot-with-buildroot.git

*download buildroot #git clone git://git.buildroot.net/buildroot

#cd buildroot

check the latest stable release #git tag

checkout the latest #git checkout 2018.05

*clean any old configuration

#make defconfig #make clean #make qemu_arm_versatile_defconfig

copy the provided .config file into the buildroot folder #cp ../qt-embdded-qemu_arm_versatile-buildroot-with-buildroot/.config .

if you need to edit you can use

#make menuconfig

to build now run

#make

compiling will take about 45 minuets

you can run the qemu using the following command

#qemu-system-arm -M versatilepb -kernel output/images/zImage -dtb output/images/versatile-pb.dtb -drive file=output/images/rootfs.ext2,if=scsi,format=raw -append "root=/dev/sda console=ttyAMA0,115200" -serial mon:stdio -net nic,model=rtl8139 -net user,hostfwd=tcp::10022-:22

now you can set password using the following command #passwd

Testing the output

from qemu terminal run

#cd usr/lib/qt/examples/gui/analogclock/ #./analogclock -platform linuxfb

it should display analog clock on qemu emulated display

You can use ssh from host using the command

#ssh root@localhost -p10022

<<<<<<< HEAD

you can now send command using ssh

update framebuffer resolution

fbset -fb /dev/fb0 -g 800 600 800 600 16

If you need to create bridge network to provide separate ip for the qemu guest you have to do :

enable ability to run dhcp during boot of qemu image. #make linux-menuconfig

go to network support> TCP/IP networking > kernel level auto configuration

enable it.

enable e1000 intel ethernet network driver which will be emulated via qemu

go to Device Drivers > Network device support > Ethernet driver support > intel devices

enable all intel devices

run in buildroot path

#qemu-system-arm -M versatilepb -kernel output/images/zImage -dtb output/images/versatile-pb.dtb -drive file=output/images/rootfs.ext2,if=scsi,format=raw -append "root=/dev/sda console=ttyAMA0,115200,ip=dhcp" -serial stdio -device e1000,netdev=network0,mac=52:22:00:d1:55:01 -netdev tap,id=network0,ifname=tap0,script=no,downscript=no

if you need to pass ctrl+c to the qemu use :

qemu-system-arm -M versatilepb -kernel output/images/zImage -dtb output/images/versile-pb.dtb -drive file=output/images/rootfs.ext2,if=scsi,format=raw -append "root=/dev/sda console=ttyAMA0,115200,ip=dhcp" -serial mon:stdio -device e1000,netdev=network0,mac=52:22:00:d1:55:01 -netdev tap,id=network0,ifname=tap0,script=no,downscript=no

before doing that you will have to create bridge and tap interfaces on your host device :

create bridge on host system

sudo ip link add br0 type bridge

clear the ip address of the host system

sudo ip addr flush dev eno1 (in some cases use eth0 instead of eno1)

connect the host ethernet connection to the new bridge

sudo ip link set eno1 master br0

create new tap interface on the current user called tap0

sudo ip tuntap add dev tap0 mode tap user $(whoami)

add that new tap to be connected to the bridge

sudo ip link set tap0 master br0

make sure everything is up :

sudo ip link set dev br0 up

sudo ip link set dev tap0 up

better to restart the network service using #sudo /etc/init.d/networking restart
update dhcp using

sudo dhclient

TODO : -upload automatic script to configure the network on host - create patch file to configure buildroot .config and make new defconfig
