CV-SDK containerized on Axis Q1615 Mk III - ARTPEC-7

[swarali-nandgaonkar]

As the Q1615 MKIII work with ARTPEC-7 i.e. I assume the architecture is arm7l i.e. arm7hf. The OS is 11.11.73. For this specific case, are are no examples in the CV examples library. I specifically need help for the dockerfile. Where can I find help/examples related to this?

Hi @swarali-nandgaonkar ,
You can still use the v1.15 tag for armv7hf:

Hi @vivekatoffice, thank you for your response. I tried building the hello-world example from this repo, and see an error while building the image-

I'm not sure if this has something to do with docker or acap or my personal settings. I was also unable to build any of my previously working applications because of this error. Could you please help if you have an idea about this?

Update:

Modifying dockerfile with
ARG DEVICE_PLATFORM=linux/arm/v7
FROM --platform=$DEVICE_PLATFORM ubuntu:${UBUNTU_VERSION} AS runtime-image-armv7hf

instead of

FROM arm32v7/ubuntu:${UBUNTU_VERSION} as runtime-image-armv7hf
FROM arm64v8/ubuntu:${UBUNTU_VERSION} as runtime-image-aarch64

and installing qemu to allow build for a different architecture solved the problem with building the image.
docker run --rm --privileged multiarch/qemu-user-static --credential yes --persistent yes

Could anyone explain why this is needed at all? It wasn't needed earlier.
