RPi3 12.0-CURRENT Kernel Build

I'm having an issue building my kernel, and I'm not sure what is causing it. This is what I am getting:
Code:
linking kernel.full
unknown emulation: aarch64elf
line 19: : expected, but got (
  PROVIDE (etext = .);
          ^
*** Error code 1

Stop.
make[2]: stopped in /usr/obj/usr/src/sys/MYKERNEL
*** Error code 1

Stop.
make[1]: stopped in /usr/src
*** Error code 1

Stop.
make: stopped in /usr/src
Any advice would be greatly appreciated.

Have you tried using Crochet to build an image? It is quite easy.
https://github.com/freebsd/crochet

pkg install u-boot-rpi3 aarch64-binutils
git clone https://github.com/freebsd/crochet /crochet
cd /crochet
./crochet.sh -b RaspberryPi3

After completion image name will be shown. Your image may have a different name.

cd /crochet/work
dd if=FreeBSD-aarch64-12-GENERIC-UP.img of=/dev/da0 bs=10240 conv=sync

I'm just trying to compile a new kernel on my RPi3 itself. I shouldn't need crochet to do a simple make buildkernel KERNCONF=MYKERNEL I have also tried with adding TARGET=arm64

I wrote something ignorant and deleted it.
My point is why fight it. I am presenting the easiest method. Use it and study the results. Then try to build your own.
For instance: RPi3 is probably the hardest of all Arm builds. Have you built any well supported devices like RPi2?
Crossbuilding for Arm is not easy. I would rate it complex.

Yes RPi3 is very hard to build. I tried using Crochet to build my image, but I wasn't able to get it working right. I found the image I'm currently useing from http://www.raspbsd.org/. So right now I'm just wanting to update my kernel. I've tried building a generic kernel as well as a custom one, but I keep getting the error I posted in my initial post no matter the configuration.

You do realize that swapping kernels is not really the way to upgrade FreeBSD.
Swapping/upgrading kernels is used more for adding devices or services which are not supported.
You really need to build the whole world. Swapping in a kernel from a different source tree sounds like a disaster.

I just used my instructions for Crochet after I just downloaded the newest source with svnlite co .
I am using my instructions exactly on a fresh build box. What part of Crochet did not work for you?
unknown emulation: aarch64elf
I am pretty sure this is a problem. Are you sure your setenv is correctly set to aarch64?

What is the kernconf you are using for building your kernel? There is no RPI3 kernconf in source. Are you using -GENERIC on ARM64?

OK Just finished. All compiled fine. Updated the source on my 11.1 Build box.

I also realize that you generally buildworld as well, and I plan to do that. One problem at a time I figure.

Also I did get Crochet to build an img, but I was never able to get it to boot.

I just got back and realized I built that on FreeBSD 11.1. Even with -CURRENT source it won't work. I am checking now.
You must use crochet on FreeBSD -CURRENT for RPi3.
The RaspBSD image is created with Crochet.

Yes that image from 11.1 won't boot. I am updating my FreeBSD -CURRENT box now. I will let you know how it works when complete.

Mine didn't boot either but I think I know where the real problem is- u-boot. It has been through some recent changes.
That is where my money is. Find an older version of the u-boot-rpi3 port and I bet it works..
I say that because u-boot is the first thing to load and it does not. My image from March -CURRENT does.
It is possible the crochet board file might need updating for the new u-boot work.
I didn't see any FreeBSD Arm mailing lists mentioning any rpi3 problems.

I don't think the FreeBSD Arm mailing list is working properly. I sent an email about my problem, and never got anything back.
