If shell from which AGL was built is closed, or new shell is opened, then it is needed to re-initialize build environment:
$ source $AGL_TOP/build-virtio-aarch64/agl-init-build-env$ runqemu |
|---|
4.2 QEMU/KVM on AGL Reference Hardware
...
4.2.2 Flash AGL minimal image root file system to the second partition on SD-Card or eMMC.
Ex. SD-Card (/dev/sdb)
$ cd build-virtio-aarch64/tmp/deploy/images/virtio-aarch64$ sudo dd if=agl-image-boot-basesystem-virtio-aarch64.ext4 of=/dev/sdb2 |
|---|
4.2.3 Build AGL minimal image for AGL Reference Hardware.
$ source meta-agl/scripts/aglsetup.sh -m h3ulcb -b build-h3ulcb agl-demo agl-refhw-h3 |
|---|
In build-h3ulcb/conf/local.conf add
AGL_DEFAULT_IMAGE_FSTYPES = "ext4"IMAGE_INSTALL_append = " \ qemu \ util-linux \ // needed to enable kvm on qemu" |
|---|
Build image:
$ bitbake agl-image-minimal |
|---|
Add virtio kernel to the AGL Reference Hardware Linux rootfs:
$ cp build-virtio-aarch64/tmp/deploy/images/virtio-aarch64/Image build-h3ulcb/tmp/work/h3ulcb-agl-linux/agl-image-minimal/1.0-r0/rootfs/linux2$ bitbake agl-image-minimal -c image_ext4 -f$ bitbake agl-image-minimal -c image_complete |
|---|
Flash root file system to the first partition on SD-Card or eMMC.
Ex. SD-Card (/dev/sdb)
$ cd build-h3ulcb/tmp/deploy/images/h3ulcb$ sudo dd if=agl-image-minimal-h3ulcb.ext4 of=/dev/sdb1 |
|---|
4.2.4 Boot AGL Reference Hardware board using Linux located on the first partition of SD-Card or eMMC.
4.2.5 Run QEMU from Linux 1 command line
Ex.
taskset f qemu-system-aarch64 \ -machine virt \ -cpu cortex-a57 \ -m 2048 \ -serial mon:stdio \ -global virtio-mmio.force-legacy=false \ -drive id=disk0,file=/dev/mmcblk1p2,if=none,format=raw \ -device virtio-blk-device,drive=disk0 \ -object rng-random,filename=/dev/urandom,id=rng0 \ -device virtio-rng-device,rng=rng0 \ -nographic \ -kernel /linux2 \ -append 'root=/dev/vda rw mem=2048M' \ -enable-kvm \ -device virtio-mouse-device \ -object input-linux,id=mouse1,evdev=/dev/input/by-path/platform-ee080000.usb-usb-0:1:1.0-event-mouse \ -device virtio-net-device,netdev=net0 \ -netdev user,id=net0,net=192.168.10.0/24 |
|---|
NOTE: mmcblk1p2 above is used for when root file system is flashed on SD-Card.
NOTE: To enable KVM using -enable-kvm option, use taskset command to bind a process to a given set of CPUs on the system.
