Command line configuration program:

raspi-config

apt update && sudo apt upgrade -y

apt install apache2

free -m

swapoff -a
dd if=/dev/zero of=/swapfile bs=1M count=1024
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile

Add to /etc/fstab:

/swapfile none swap sw 0 0

apt install autofs nfs-common -y

Edit /etc/auto.master:

/net /etc/auto.nfs --timeout=60

Edit /etc/auto.nfs:

systemctl enable autofs
systemctl restart autofs

Note: CVBS is on sleve; Gnd is ring 3. It is enabled when no HDMI monitor is connected.

In /boot/firmware/config.txt:

enable_tvout=1
dtoverlay=vc4-kms-v3d,composite

Ensure hdmi_force_hotplug=1 is commented out or set to 0.

In /boot/firmware/cmdline.txt, either:

vc4.tv_norm=PAL
vc4.tv_norm=NTSC

To control overscan, see settings:

margin_left
margin_right

Divide value by 1000 to get temp in C:

CPU Core throttling above 80 C.
