12.1.0 release candidate 3 (build 16) released
Hi, We're pleased to announce the next release candidate of our new 12.1.0 software release. Information and installation instructions can be found here: http://wiki.laptop.org/go/Release_notes/12.1.0 Quick links for those who know which files need to be grabbed and save to USB disks: http://download.laptop.org/xo-1.75/os/candidate/12.1.0-16/ http://download.laptop.org/xo-1.5/os/candidate/12.1.0-16/ http://download.laptop.org/xo-1/os/candidate/12.1.0-16/ This is a signed release candidate that can be installed on all XOs, even those with security enabled. We're looking for testing and feedback on all aspects of the system. Thanks for any help you can offer, and for all the feedback that was received throughout development. Our scheduled release date is July 9th. Please review the Known problems section of the release notes. Some documented issues are carried over from previous releases, but others are new and are things that we will aim to fix in the time remaining before release. Compared to 12.1.0 release candidate 2 (build 15), we have fixed and changed: The Welcome screen (and activity) has been updated with new content providing a quick introduction on how to use Sugar and the XO. Implode has been fixed to show the animated help information again (SL#3463). Labyrinth can now resize images without hanging (SL#3669). A sugar-artwork update fixes drawing of the SpinButton widget in Read and Abacus (SL#3406) and the bookmark edit area in Read (SL#3561). The totem media player in GNOME was failing to launch; we've reverted to an older version to fix that. Ogg media on websites now works again: the totem-based media player plugin has been fixed to display this media in most cases (#11963), using WebKit's own media support in the other cases. When the webkit internal audio support is used, we've fixed the display of the playback controls (#11913). The battery meter now behaves better when plugging/unplugging AC power (#11957). Booting after activation no longer results in misnamed network devices (#11967) and loss of mesh networking on XO-1 (#11975). After activating, the black cursor no longer appears on top of the boot animation or on the desktop (#11940). A new instability in the XO-1 wireless driver has been fixed (#11941). XO-1.5 has been fixed for manufacturing tests involving suspend/resume (#11867, #11964). The manufacturing tests also exposed a bug in how the wtmp file is updated on shutdown, that's been fixed too (#11952).

Our standard defconfig has many drivers enabled as modules. To make things easy during development however, we usually build monolithic kernels. It saves you from having to copy all the drivers along with the kernel. So I run a quick search and replace over the defconfig file, changing every location where a driver is set to module (=m) to be a built-in driver (=y).

Re: 12.1.0 release candidate 3 (build 16) released
At this point in time there would have to be a significant reason to include a full activity update as opposed to creating a new dotted activity version with a specific fix. As mentioned in Daniel's email the final release is currently scheduled for July 9th. The final build therefore needs to be tested before that date. We are looking for versions we know are stable, not the most recent bugfixes.

With dot I'm getting 0 as result. Sorry about that. The Forth word . pops an item from the stack and prints it as a number in the current radix. Okay, this means that during 300ms of listening on the specified channel, the wireless device was unable to receive any of the multicast packets from the sender. The transmit power used by the NANDblaster sender is likely to be much lower than the transmit power used by your access point. The result of the RF link budget [1] may not allow successful receive. You are right. There is around -20 difference between working and this xo. Try placing this XO with the antennas 25cm from the sender, with the antennas of both XO set vertical. I'm now convinced you have an antenna cable problem that needs maintenance. There is likely to be about 20 dB extra loss in the cables, compared to the working XO. As an optimisation, you can also use test-antenna to find which XO has the best RSSI, and use that XO as the NANDblaster sender. A high RSSI also means the XO will transmit better, in most cases.
