Thank you for suggestion, Anyware I had the same problem if I use

if {[expr [have_board virt_qemu] && [have_spec arm_64]]} { return "virtio_nic_drv" }

There are no any file like virtio_nic_drv build :

Hi Alexander,

I'm not especially familiar with ARM virt platforms but I can tell from your error log that your run scripts attempts to import the archive src/virtio_mmio_nic because of these lines:

! if {...} { return "virtio_mmio_nic" } ! ... ! lappend depot_pkgs [depot_user]/src/[binary_nic_drv] ! ... ! import_from_depot $depot_pkgs

And fails to find the archive. Furthermore, the archive is at least not part of the "official" repos:

! $ find repos/ -type d -wholename *recipe*virt*nic* ! repos/os/recipes/src/virtio_nic_drv

Have you tried using the 'src/virtio_nic_drv' instead? It seems to support arm, arm_64, and x86:

! $ ls repos/os/src/drivers/nic/virtio/spec/ ! arm arm_64 x86

Cheers, Martin

Where I can find example of usage virtio nic for arm ?

I try to use scrcpy sample for universal run file , and add something like below - but it fail:

thank you for advice, it works. The only problem I have now is foc and network drivers. I do not find suitable combination to check

make -C build/arm_v8a/ KERNEL=foc BOARD=rpi3 run/sntp_client make: Entering directory '/var/services/homes/admin/gen/22.05/build/arm_v8a' including /var/services/homes/admin/gen/22.05/tool/run/power_on/qemu including /var/services/homes/admin/gen/22.05/tool/run/log/qemu including /var/services/homes/admin/gen/22.05/tool/run/boot_dir/foc including /var/services/homes/admin/gen/22.05/repos/libports/run/sntp_client.run Using NTP server 94.247.111.10 Error: recipe for 'pkg/drivers_nic-rpi3' not found - unable to guess version

and another try make -C build/arm_v8a/ KERNEL=foc BOARD=virt_qemu run/sntp_client make: Entering directory '/var/services/homes/admin/gen/22.05/build/arm_v8a' including /var/services/homes/admin/gen/22.05/tool/run/power_on/qemu including /var/services/homes/admin/gen/22.05/tool/run/log/qemu including /var/services/homes/admin/gen/22.05/tool/run/boot_dir/foc including /var/services/homes/admin/gen/22.05/repos/libports/run/sntp_client.run Using NTP server 185.209.85.222 Test requires base-foc kernel archive, which is missing for this build configuration SPECS="arm_v8a foc arm_v8 arm_64 64bit neon»

as I understand, virt_qemu does not support x86?

Please try

make -C build/arm_v8a run/sntp_client KERNEL=hw BOARD=virt_qemu

and if it works derive your run script from

repos/libports/run/sntp_client.run

I tested the scenario just now and it worked.
