Hello.
I have a problem with cross:

Please help!

can you try cross build --target=arm-unknown-linux-gnueabihf --features bbb -vvv --release and see if it progresses?

Can you also show me output of docker info

[hanusek]

I solved it.
The reason was docker-desktop. When I disabled docker-desktop, it worked.
