That’s been available on earlier versions of the Pi (2B v1.2, 3B, 3B+).
It was not available at launch for the Pi 4, but was released in beta firmware in late September, and is currently part of the critical firmware update.
It works well, allowing separate boot images for each individual Pi on your network.
- znpy 6y agoyup, i tried netbooting on the 3b+, with root on nfs and without an sdcard. > It works well, allowing separate boot images for each individual Pi on your network. could you elaborate a bit more on that?
- notanote 6y agoWhen using netboot, the boot rom will pull the files it needs from the tftp server. It will first look for them in a subdirectory with the Pi’s serial number as its name. If you’re netbooting without any sdcard installed, I’d suggest disabling sd polling.
- buggeryorkshire 6y agoPXE uses the MAC address doesn't it?
- jedieaston 6y agoIt does, but I think what the Pi does is connect to the TFTP server handed out by PXE and then look for a folder named serial-number. If it doesn't exist in the path PXE gave it it just boots whatever is in the tftproot.
- vetinari 6y agoMight or might not. It does DHCP request and server-side, you can do decision on what it returns on any tag you want, often client architecture (0x93); you can then point to the right tftp server, or if you have UEFI client, you can also use http.
- sitkack 6y agoIntel should be making an Optane sdcard for embedded use, potentially with a built in power down capacitor to make sure all acknowledged writes make it to Optane.
- pengaru 6y ago> It works well, allowing separate boot images for each individual Pi on your network. Isn't that a natural capability with PXE implemented at the server keyed off the MAC address?
