How to install signed build 18 of release 13.2.6 on XO-1, to an SD card in the external slot.

ALL USER DATA WILL BE ERASED FROM THE CARD!

Ingredients

You will need an SD card of at least 4GB capacity; it will be erased by installing, and should remain in the laptop.

You will need a USB drive of at least 1GB capacity, but only for the duration of the installation. We recommend the drive be FAT formatted, but other formats are supported, see how to prepare a drive for use by the firmware for more details.

You will need an XO-1 laptop. It may be either locked or unlocked.

Recipe

Preparing the USB drive

  • download 32019o0.zd (602 MB) and save to the USB drive,
  • download 32019o0.zd.zsp.fs0.zip (1 MB) and save to the USB drive with file name fs0.zip,
  • check the USB drive has two files; 32019o0.zd and fs0.zip,

Preparing the XO-1

Installing

  • insert the USB drive and the SD card into the XO-1,
  • hold down all four game keys above the power button, turn on the XO-1, and wait for the message Release the game keys to continue,
  • release the game keys, progress will be displayed, some grey blocks will turn green, and the screen will show:
 Blocks/square: 2        Total blocks: 15283     Now writing: 70  0 %
 Installing to SD card ..... please wait.
  • after a few minutes it will show:
 Blocks/square: 2        Total blocks: 15283     Now writing: 0  0 %
 Rebooting in 10 seconds ... please wait.

At this point it is finished. You may remove the USB drive then, during the reboot, or after the reboot.

Warning

Do not remove the SD card.

It is best to leave the SD card in the same XO-1, because;

  • the install is a good test of the XO-1, SD card slot, SD card, and compatibility,
  • unnecessarily exercising the card slot contacts of very old hardware is likely to cause reliability problems,
  • booting from the card and then moving the card to another XO-1 will cause software problems. You may need to Discard wireless connections in the Network panel of My Settings. See also imaging side effects, in particular the sections regarding .olpc-configured, and network.

Testing

Verify the XO-1 has booted from SD card: in the Sugar home view, right-click on the Journal icon, and look at the free disk space. For an 8 GB SD card, the free space is about 5750 MB. Or use Terminal command df and observe the root filesystem is on /dev/disk/mmc/mmc0p2, like so; 

[olpc@xo-93-c1-cf ~]$ df /
Filesystem           1K-blocks    Used Available Use% Mounted on
/dev/disk/mmc/mmc0p2   7679632 1772792   5887976  24% /
[olpc@xo-93-c1-cf ~]$ █

Try rebooting several times to make sure the SD card is used each time. Unreliable combinations may cause the laptop to boot from internal storage instead.
