The first step would be that somebody = else confirms my finding that building and running a custom kernel on a = stock FreeBSD 13.1-RELEASE on RPi 4 does not work out.

Summary of the later material: It would appear that if building any kernels are broken, it is specific to some custom kernel(s) in question, not to building kernels in general. 13.1-RELEASE's install is able to build, install, and boot its own generic kernel on a 8GiByte RPi4B Rev. 1.4. How I got to that conclusion . . . (Written earlier.) I'm doing (written as I go along): Establish a USB3 media from = FreeBSD-13.1-RELEASE-arm64-aarch64-RPI.img.xz and releases/arm64/13.1-RELEASE/src.txz . Set up some basic = configuration. (Note: growfs is broken for the large expansion. I used dump and restore for the ufs partition from a mounted non-grown dd of the .img file to other media. I also copied over the msdosfs partition content. I set up to have partition-based swap space as well. I used gpt partitioning.) Boot via that media on a 8 GiByte RPi4B Rev. 1.4 . Do some live setup to finish things off.

Notes: The builds were done via being logged in via ssh. The serial console causes more time to be taken waiting for the build output as it progresses, so I avoid it for builds. This media will be around for some time to possibly do other experiments with if desired. Provide explicit instructions if you want a build tried. The starting context would be as above but the instructions might say to "rm -fr" various things first, if appropriate. =3D=3D=3D Mark Millard marklmi at yahoo.com
