FreeBSD 14.0 Compiling kernel for Raspberry Pi 4B
FreeBSD 14.0 Compiling kernel for Raspberry Pi 4B
in 4 easy steps, updated December 13, 2022
- Start with a downloaded RPI image .img FreeBSD snapshot file you can write into a USB Flash drive. decompress the file with command: xz -dv freebsd_raspi.img
- Boot the from USB Flash drive image built from a Snapshot image
- Use the running Snapshot image FreeBSD use "bsdinstall" to download and install FreeBSD, over the ethernet cable connected to your router, to the external usb Hard drive or SSD drive.
- Shutdown reboot, remove the USB Flash drive stick from the RasPi4B, reboot from the external usb Hard drive or SSD drive.

Here is the September 9, 2022 FreeBSD 14.0 Snapshot image for RPI 3 or 4, right click on to "save as" a file on your local hard drive. or use either of the commands:
curl -O https://url_link
wget -c https://url_link
FreeBSD-14.0-CURRENT-arm64-aarch64-RPI-20221209-b1ef176eb528-259626.img.xz This is a December 9 2022 image
Write the uncompressed .img file into a USB flash drive.
- Download file first ,
- then second uncompress the .xz file to an .img file,
- third write into a USB Flash drive using a tool appropriate to your operating system.

Download and install Raspberry Pi Imager to a computer with an SD card reader.
Put the SD card you'll use with your Raspberry Pi into the reader and run Raspberry Pi Imager. in a Terminal window.

Setup the Raspberry Pi to boot from a USB flash drive. Insert the made USB flash drive to boot the raspberry pi 4B hardware. Run the raspi-conf program to update the hardware configuration to boot from USB Flash drive before Micro SD card.
Attach a USB SSD and run "bsdinstall"
Attach an external USB hard drive (or SSD) via a USB 3.0 cable (or USB 2.0 cable)
Run command line "bsdinstall" and install FreeBSD 14.0 from over the ethernet internet to your blank SSD drive. Afterwards, "shutdown -r now", remove the USB flash drive after shutdown and before reboot. The system should boot from external USB hard drive (or SSD). Congratulations you have a booting functioning FreeBSD operating system installed to your hard disk or SSD. Enjoy the fruits of your labor.

Booting from external USB SSD
After booting up a Fresh FreeBSD kernel from the external USB SSD with a Ethernet cable connected from Gigabit RJ-45 Ethernet port to your router. Check that you are connected to the internet. First check that you can ping the router: ping -c 3 192.168.1.1 or ping -c 3 192.168.0.1
ping -c 3 8.8.4.4 IP number for Google DNS
ping -c 3 he.net IP Name for Hurricane Electric IP network provider. Also Supports IP6 networking
ping -c 3 ghostbsd.org
Verify the local time and that the nntp time daemon has updated the local time clock for FreeBSD.

Patching FreeBSD source code tree with HDMI Audio vchiq patch
[PATCH] Experimental vchiq and bcm2835_audio support for arm64 and arm32

https://lists.freebsd.org/archives/freebsd-arm/2022-February/000949.html Marcos Patchfile sourceSelect the whole patch source code from above URL link, copy, paste into a filename like "HDMI_VCHIQ_sound_patch.txt". Then follow steps below to patch kernel source code as ROOT user in source code directory base /usr/src
https://reviews.freebsd.org/D36431 <https://reviews.freebsd.org/D36431>Does this match your usage work flow? I am asking you to verify the steps,
so that I or others can duplicate those steps and have a working kernel to install.
please modify, add, or update the steps below:
su root
cd /usr/src
patch -v <HDMI_VCHIQ_sound_patch.txt
time make -j4 buildkernel KERNCONF=GENERIC-VCHIQ
or time make -j4 buildkernel KERNCONF=GENERIC-VCHIQ -DNO_CLEAN
time make -j4 installkernel KERNCONF=GENERIC-VCHIQ
reboot FreeBSD operating system and use the newly compiled kernel
uname -aK What is the presently running kernel version.
ls -l /boot/kernel Look at the file sizes and file dates FYI
Now I expect that HDMI port #0 sound will work and output to my Television connected via HDMI cable to TV's HDMI input #2. So when my tv is displaying the Raspberry Pi 4B desktop screen. Opening FireFox version 104 browser to youtube.com will play some Video and AUDIO too.
Your thoughts are welcome in the comments below?
ps. I tested the above steps for rebuilding my FreeBSD 14.0-CURRENT kernel and installing FreeBSD 14.0-CURRENT GENERIC-VCHIQ kernel. It worked and I opened Firefox Browser and played Youtube videos. This made the audio sound come out the mini-HDMI port and play on the Television speakers. WOW! Great advance. Made the FreeBSD distro installation come alive on my Raspiberry Pi 4B.

Marco's Reply with simple test outputs
stock config.txt and dtb-s. dmesg should then show vchiq0: <BCM2835 VCHIQ> mem 0x7e00b840-0x7e00b87b irq 72 on simplebus0 vchiq: local ver 8 (min 3), remote ver 8. pcm0: <VCHIQ audio> on vchiq0 and cat /dev/random > /dev/dsp should play static If nothing’s playing, flipping the sysctl dev.pcm.0.dest through - 0: both hdmi and headphones - 1: headphones - 2: hdmi usually brings the audio back to life. Best, Marco
