Building with CUDA Host SDK

[nlbutts]

I'm trying to get the host SDK to include the CUDA tools. I already have nvcc and libraries installed on my Ubuntu 18.04 system, but I would like the tools and libraries be included in the SDK build. I've added
nativesdk-packagegroup-cuda-sdk-host
to
TOOLCHAIN_HOST_TASK_append
But I get the following error

WARNING: Unable to get checksum for cuda-binaries-ubuntu1804-native SRC_URI entry cuda-repo-ubuntu1804-10-2-local-10.2.89-440.40_1.0-1_amd64.deb: file could not be found WARNING: cuda-binaries-ubuntu1804-native-10.2.89-1-r0 do_fetch: Failed to fetch URL file:///home/nlbutts/projects/maza/maza-yocto/build/downloads/nvidia/cuda-repo-ubuntu1804-10-2-local-10.2.89-440.40_1.0-1_amd64.deb, attempting MIRRORS if available ERROR: cuda-binaries-ubuntu1804-native-10.2.89-1-r0 do_fetch: Fetcher failure: Unable to find file file:///home/nlbutts/projects/maza/maza-yocto/build/downloads/nvidia/cuda-repo-ubuntu1804-10-2-local-10.2.89-440.40_1.0-1_amd64.deb anywhere.

Am I suppose to manually download cuda-repo-ubuntu1804-10-2-local-10.2.89-440.40_1.0-1_amd64.deb?

It used to be that way, since the host-side tools were only available via the NVIDIA SDK Manager. NVIDIA started making them available for download recently, though, and some changes went in around the end of April into dunfell-l4t-r32.4.3 and later branches to take advantage of that change.

So if you're using a current branch, have you updated it lately?

We plan to start testing the latest updates this week. So we will hold off on the SDK changes until then. Thank you.
