Thanks, but I'm not so sure about getting users to run make install since that will put things in /usr rather than /usr/local. It's possible to use olpc-os-builder without installing it, so the instructions could be modified that way, but it's probably best to wait for Fedora inclusion: https://bugzilla.redhat.com/show_bug.cgi?id=551411 in which case the instructions become a lot simpler. If that doesn't get completed this week, perhaps its something you could take over. cheers Daniel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: Battery LED flashing

We left it plugged in overnight and it appears to have charged normally and the battery now runs the laptop (when it was doing the flashing charge, the laptop would switch off immediately when you unplug the charger). http://wiki.laptop.org/go/Power_management#Battery_LED indicates flashing on charge means trickle charging. Sadly we didn't find this page when it was happening so cannot fully confirm it was flashing orange and with the 4 blinks, pause pattern. I've updated troubleshooting guide to include the flashing yellow state. The only thing that causes the charge LED to blink is trickle and error. Flashing red is error so it was trickle. 'watch-battery' from the ofw ok prompt will also tell you trickle for the status when its trickle charging. This page also doesn't give any clues as to why a battery might be trickle charging. Battery trickles when the voltage on the battery is 5.4V. This can occur if the battery is stored for a long time or if its installed in a (powered off) XO for 30-50 days. There is a small power drain even when the XO is turned off. http://wiki.laptop.org/go/Hardware_specification#Battery suggests that the battery has a Maxim DS2756 http://wiki.laptop.org/images/e/e9/DS2756.pdf chip in it, but this chip only monitors one cell, so I guess there are two such chips? No, the Cells are in series. The sensor chip measures the voltage across both of them. Overvoltage undervoltage are monitored /cell by the safety monitor but there's no communication to that chip. The /sys interface only gives information about the whole battery, it doesn't tell you about the state of each cell. The specification pdf on the Hardware_specification page describes the Embedded Controller interface to the operating system in terms of Battery, not Cell so I guess it doesn't expose each cell either? The /cell info is not exposed because there's nothing available to expose and there's not much to do if they were. There's only one path to the battery. To do anything special you would need independent charging paths. -- Richard A.

On 01/03/2010 07:20 AM, Martin Langhoff wrote: the behavious sounds exactlt like a case of trickle charge. This triggers when the batt charge is so low that we cannot charge it (or measure it). When it happens, it's ususlly because a batt has not been used for a while. The batteries are actually ok. Trickle charge is the result of the way the XO-1 power system is designed. There is no dedicated battery charger IC. The battery is connected directly to the main voltage rail. The result of this that when you turn on the charging mosfet your system rail = battery voltage. On XO-1 if you try to charge a battery that's dropped to a really low level you don't have enough headroom for the rest of the voltage regulators to work and the system dies. So we bring the voltage back up gently to a level we can deal with before opening the electron flood gates. In terms of getting more low level info, get your hands on a script called batman.fth (it's somewhere in the wiki ;-) ) http://wiki.laptop.org/go/XO_Troubleshooting_Battery#batman.fth logs of the batt levels per cell, and you can read it/change it. batman.fth does not do anything per cell. There's no user serviceable parts per cell in the OLPC battery. -- Richard A.

Re: Android, OLPC, and native hosting
On Sat, Jan 2, 2010 at 2:09 PM, Mikus Grinbergs mi...@bga.com wrote: Speaking of android, has anyone heard anything about google's other OS, chrome OS? Installed Chrome OS on my XO-1.5 when I was using os64 - the install pulled in a whole barnful of dependencies. Did not find Chrome impressive - but it probably is the most capable HTML5 implementation currently available. What I noticed most was that the Menu Bar was rudimentary, with the entire screen sometimes being used instead of palettes. This was a beta - performance quite humdrum. On the XO, Opera is noticeably faster. I've installed Chrome OS, and wasn't terribly impressed by either its performance or its feature set. Again, it was a beta, and the build I used from from some random site, maybe wasn't a good build. What *I* was interested to see is that all the webbooks (Chrome, Android, Litl) are using the one full screen window model which OLPC got such grief for. Chrome OS has a slight variation, with floating detachable subwindows, I think. I think there's room for solid innovation here, especially since the window manager of sugar was *my* personal roadblock to productive on-XO activity development. I think this thread has wandered off into non-productivity. I encourage anyone interested to port Android to XO hardware and/or try to get good education tools working on Android. I'll also plug Google Wave here, since I think it's a good start at a robust and standardized infrastructure for the collaborative model Sugar aspires to.

Re: New release of F11 for the XO-1 - Build11
Keyboard and mouse will not wakeup from sleep. Can be fixed by disabling power management in Sugar. Is there any reason for cutting release after release that don't work unless end users disable power management (sometimes twice!)? Surely if you can't fix the bugs, you could at least ship the release with power management disabled by default, so it works out of the box. Or, one step up from that, have it figure out which hardware it can reliably suspend on, and only have it enable suspend by default on that hardware.
