install RPi4 from scratch

download 2024-11-19-raspios-bookworm-arm64-lite.img.xz
cd /daq/daqstore/olchansk/linux/Raspbian/
insert 16GB or bigger SD card into /dev/sdX
xzcat 2024-11-19-raspios-bookworm-arm64-lite.img.xz | dd of=/dev/sdX bs=1024k status=progress
fdisk -l ### to see if it worked
eject /dev/sdX
insert SD card into RPi4
power up
observe boot
observe ask for language and keyboard layout, select English/US
observe ask for create user, use "wheel" and password
observe boot to login prompt
login as wheel
sudo /bin/bash
ifconfig eth0 142.90.x.y netmask 255.255.224.0 ### use armdaq01 142.90.121.101
route add default gw 142.90.100.18
ping 142.90.100.18
systemctl restart systemd-timesyncd
date ### check date is correct
apt update
apt upgrade
(forgot to enable ssh!!!)
apt install ssh
systemctl enable ssh
rpi-eeprom-update ### check boot loader firmware version, current and available may be different
rpi-eeprom-update -a ### prepare firmware update, actual update is done on next boot
shutdown -r now ### update firmware and boot new kernel
login as wheel
rpi-eeprom-update ### check boot loader firmware version, current and available should be same
raspi-config ### in advanced options, set boot order to network-first
maybe verify the changes took, BOOT_ORDER should read 0xf21 for boot from SD card, if absent, boot from network

root@magpi03:~# vcgencmd bootloader_config
[all]
BOOT_UART=0
WAKE_ON_GPIO=1
POWER_OFF_ON_HALT=0
[all]
BOOT_ORDER=0xf21

shutdown -h now
power down
remove SD card
power up
observe it's dhcp requests

setup network booting

setup dnsmasq.conf

most important is the "pxe-service" entry to enable RPi4 tftp boot
systemctl dnsmasq restart
observe RPi4 is doing message type 2 and message type 5
followed by requests for files under /tftpboot/eb47cd4d (numbers is the RPi4 serial number)
mkdir /nfsroot/dlpi, /nfsroot/dlpi-firmware
rsync files from SD card partition 1 (VFAT) to /nfsroot/dlpi-firmware
rsync files from SD card partition 2 (ext4) to /nfsroot/dlpi
edit /etc/exportfs

edit /nfsroot/dlpi-firmware/cmdline.txt

console=serial0,115200 console=tty1 ip=dhcp root=/dev/nfs

edit /nfsroot/dlpi/etc/fstab, comment out mount of "/" and "/boot/firmware" add NFS mounts:

dlpi pings, ssh returns "connection refused"
we forgot to install and enable ssh on the SD card!!!
we forgot to mount "/" read-write, observe log files in /nfsroot/dlpi/var/log should have current times

post install

we forgot to enable ssh when we setup the SD card, enable it by hand:

cd /nfsroot/dlpi
cd etc/systemd/system
rm ./multi-user.target.wants/sshswitch.service
ln -s /usr/lib/systemd/system/ssh.socket sockets.target.wants/ssh.socket
ln -s /usr/lib/systemd/system/ssh.socket ssh.service.requires/ssh.socket
reset dlpi

cat ~/.ssh/id_ed25519.pub >> /nfsroot/dlpi/root/.ssh/authorized_keys
ssh dlpi should work now
as root@dlpi
