Specifically, the following is observed when building on opensuse tumbleweed:

Juno dropped use of this kernel as of meta-arm commit:

Since no other platforms are using this kernel, it should no longer be an issue.

Comment 2 Alexander Kanavin 2020-08-18 11:52:22 UTC

Sorry, I have to reopen: meta-arm-bsp/conf/machine/n1sdp.conf still uses the kernel, and the link provided have a failure happening with that machine too.

Comment 3 Jon Mason 2020-08-20 07:51:14 UTC

n1sdp kernel problem should be resolved in http://git.yoctoproject.org/cgit/cgit.cgi/meta-arm/commit/?id=75b337d909e191b20fcac4f1e4dad9737cb47e7e
