PXE aarch64 TFTp boot a Raspberry Pi 4B over the network, May 5 2024

 PXE aarch64 TFTp boot a Raspberry Pi 4B over the network, May 5 2024

 

PXE:TFTPd Setup 

This is one of the easiest pieces to get working.

  1. mkdir /tftpboot.  zfs list; zfs create -o compress=off arm64pool/tftpboot

  2. Uncomment the tftp line in /etc/inetd.conf.
    tftp    dgram   udp     wait    root    /usr/libexec/tftpd      tftpd -l -s /tftpboot
    # enable the ftp server
    ftp    stream  tcp     nowait  root    /usr/libexec/ftpd       ftpd -l

  3. Add inetd_enable="YES" to your /etc/rc.conf.

  4. Run /etc/rc.d/inetd start.

    Now that the server is working, we need the boot loader that will be served via TFTP to the PXE loader on your machine. for x86_64, maybe for aarch64 needs a different pxeboot file and file name??

    cp /sys/boot/i386/pxeldr/pxeboot /tftpboot
 zfs create  example
root@Ghost14-selfbuilt-rpi4B-nginx-tst1:~ # zfs create -P -o quota=5G -o mountpoint=/tftpboot arm64pool/tftpboot
create    arm64pool/tftpboot
property    quota    5G
property    mountpoint    /tftpboot

zfs set compress=off  arm64pool/tftpboot

 # zfs list arm64pool/tftpboot
NAME                 USED  AVAIL  REFER  MOUNTPOINT
arm64pool/tftpboot    96K  5.00G    96K  /tftpboot
