We use a few different methods to install operating system images.
| installation method | what files are required | how to install | references |
|---|---|---|---|
| block signed | .zd and fs.zip | hold down the four game pad buttons and then turn on the laptop | Release notes |
| block unsigned | .zd alone | check if security is enabled, if so obtain developer key and disable-security, interrupt boot, then use the fs-update command | Release notes |
| nand signed | .img and fs.zip | hold down the four game pad buttons and then turn on the laptop | Release notes Clean Install Procedure Nandblaster_for_XO-1 |
| nand unsigned | .img and .crc | check if security is enabled, if so obtain developer key and disable-security, interrupt boot, then use the copy-nand command | Release notes Clean Install Procedure Nandblaster_for_XO-1 |
| nand partitioned |
.dat and .img | check if security is enabled, if so obtain developer key and disable-security, interrupt boot, then use the update-nand command | Used by DebXO. Used by UBIFS experiments. See also Technical description. |
The signed installation methods are the same for XO-4, XO-1.75, XO-1.5 and XO-1. This was by design, since we do not wish to increase the training burden for the deployment teams.
A deployment will typically sign their builds and inject deployment keys at manufacture or on site.
The unsigned installation methods depend on the type of internal storage. XO-1 has raw NAND Flash. XO-1.5, XO-1.75 and XO-4 have microSD or eMMC managed Flash.
