== Known issues in development/testing releases == |
|||
The (draft) [[Release notes/11.2.0]] page describes limitations and issues that we anticipate will be present in the final release. In addition, as we are still in development, so we're still encountering serious issues here and there that we'll fix as we move towards release. Those cases are documented here. |
|||
=== XO-1.5 firmware complains that "not all blocks were written" === |
|||
When installing the new image with <tt>fs-update</tt> on an XO-1.5 laptop that has a development firmware version, a WARNING message may appear at the end of the process stating that not all blocks were written. |
|||
Unless your download has become corrupt, this error message is incorrect and can be ignored. Simply power off the system and turn it on again to boot into the new release. Your firmware will then be automatically upgraded (in the presence of external power) in order to solve this problem for any future installations. |
|||
The final release image will include some trickery that detects when old firmware is in use during the installation stage, and hides this invalid error. |
|||
=== os21: XO-1.5 wireless card reset bug === |
|||
<s><trac>10944</trac>: In build 21, a minor kernel bug causes the wireless card to be reset during every resume, destroying any established connections.</s> <b>Fixed in build 22</b> |
|||
=== os20 and os21: olpc-update broken === |
|||
<s><trac>10942</trac>: If using olpc-update <em>from</em> os20 or os21 to another image, things will fail badly due to a misconfigured /versions/running symlink. It will delete the current version (perhaps rendering the system unusable on reboot) and then fail to update with a strange error regarding the /versions/contents directory.</s> <b>Fixed in build 22, but you will have to reflash to install this new version - sorry!</b> |
|||
=== XO-1 JFFS2 olpc-update to os20 broken === |
|||
<s><trac>10929</trac>: If starting with an older release that used the JFFS2 filesystem (e.g. 10.1.3, 8.2.1) and using <tt>olpc-update</tt> to update to 11.2.0 build 20, you will find that it works fine during first boot, but then fails to boot the second time (and onwards). You'll have to reflash to recover from this, sorry.</s> <b>Fixed in build 21.</b> |

|||
Insert the USB drive into the XO-1.5, get to the [[Ok]] prompt and type: |

Insert the USB drive into the XO-1, get to the [[Ok]] prompt and type: |
|||
update-nand u:\os''XX''.onu |
|||
where ''osXX.onu'' is the .onu file you downloaded, for example os22.onu. |
|||
(Watch out, there's a trap. Never use ''copy-nand'' for this release. ''copy-nand'' was for previous releases with .img and .crc files, but we no longer use it for .onu and .uim files. ''copy-nand'' might seem to finish okay, but your XO-1 won't start. If that happens, do it again using ''update-nand'' as above.) |

sudo olpc-update 11.2.0_xo1.5-XX |

== What happened to 11.1.x? == |
|||
At the time of planning this release around Fedora 14 for XO-1 and XO-1.5, we are in the interesting situation where software development for the ARM-based [[XO-1.75]] is restricted to developing around F12/F13. The 11.1.x space is therefore reserved for a F12/F13 release for XO-1.75. In the future, we hope to produce joint software releases for all 3 laptops. |
|||
This oddity is expected to be a one-off; as soon as Fedora/ARM reaches Fedora 14, XO-1.75 releases will be able to share the same base (and versioning) as XO-1/XO-1.5 releases. |
