[SOLVED] July 002839 post: u-boot.bin Not Booting on Raspberry Pi 4B? Replace with older working version u-boot.bin

Yes, I also had problems with booting latest FreeBSD 14.0-CURRENT 
snapshot on a Raspberry Pi 4B with 8 GB ram  SoC B0T version 1.2

[SOLVED] answer to replace u-boot.bin with an older working version

How to Audit your directories and files using MD5DEEP or HASH utility.

Read the comments section  verify what the MD5 checksum is on your 
u-boot.bin  file.  Replace that newer u-boot.bin file with an older 
version that does work to boot the RASPBERRY PI.

Look at the size and the MD5 checksum value to determine a working 
version compared to a broken version

I would be glad for your testing assistance on Raspberry Pi 4B with 
FreeBSD software.

See the VCHIQ_AUDIO_PATCH_file.txt , https://reviews.freebsd.org/D37878  
This patch allows HDMI Audio to work on the speakers from your HDMI TV / 
Monitor.

cd /usr/src

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
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.

Respectfully,

Fred L Finster
