nEDM

Raspberry Pis on nEDM

For simplicity, all Raspberry Pis connected to the network at the nEDM experiment are booted via NFS. This allows us to deploy changes of the software to all devices very efficiently.

To install a new device, download rasb_pi.img.gz and flash it to your SD card:

gunzip -c rasb_pi.img.gz | sudo dd of=/dev/sd_card

where /dev/sd_card is the correct path to the SD card.

Then, simply connect to the nEDM network.

Network setup

documentation for advanced users

By and large, the configuration of the NFS boot follows instructions available around the web.

A few points:

1. We use the Synology raid server (link will function when connected to the nEDM VPN) as our NFS mount.
2. Our DHCP settings look like:

class "raspberries" {
  match if ( substring(hardware,1,3) = b8:27:eb );
  default-lease-time 115200;
  option root-path "192.168.1.9:/volume1/Raspberries/boot/current,tcp,vers=3";
}
