XO-4 not resuming after suspend
I have an XO-4 B1, OFW Q7B14, EC Firmware 0.3.10, os28. It won't resume after suspend, but sometimes it does. I couldn't reproduce the bug, but it happens most of the time. Here's the last lines of serial output before suspending: [ 1893.876075] pxa168fb_release GFX layer, fbi 0 opened 4 times [ 1911.036158] PM: Syncing filesystems ... done.

Firmware upgrade not working on XO-4 B1
Hi, everyone I have an XO-4 B1 with os27, QB711 and ec 0.3.04. It won't upgrade the OFW, EC firmware or touchscreen firmware.

Problem running signed actos/actrd from USB stick on secured XO-1
Hi everyone, I'm trying to use signed actos/actrd from a USB stick for testing purposes, but I'm getting a modprobe: module scsi_wait_scan not found in modules.dep message and then lots of: mount: mounting /dev/sda2 on /sysroot failed: Device or resource busy ending with: No root device found Boot has failed, sleeping forever. This initramfs works fine when security is disabled. I wrote a custom olpc.fth with this changes: ro root=mtd0 rootfstype=jffs2 console=ttyS0,115200 console=tty0 fbcon=font:SUN12x22 expand$ to boot-file disk:\boot\vmlinuzexpand$ to boot-device disk:\boot\actrd.img expand$ to ramdisk so initramfs and kernel are loaded from the USB stick and the modules can be found in the NAND flash. It also works when I copy the actos.zip and actrd.zip files to /boot in internal storage. The USB stick has 2 partitions: the first one is a FAT16 partition with a boot directory containing the signed files. The other one is an ext4 partition labeled OLPCRoot, and it only contains a /lib/modules* tree, since my customized initramfs will only fix the hwclock and then power off the XO. Any clues?

Re: Problem running signed actos/actrd from USB stick on secured XO-1
I've only created a dracut module, leaving everything else intact. Maybe I should trim some stuff, uninstall some other modules? I've used the default dracut-olpc-config and added mine. Error messages are shown right after the Hello, children of the world message. I'll try to cut some stuff and let you know how it went.

It sounds like something isn't quite as you expect in your initramfs, because if it will *only* fix the hwclock and power off, its not clear why it is trying to mount the root partition.

Re: [PATCH] olpc.fth - grow the root filesystem partition on boot
Hi everyone! I wrote a dracut module a couple of weeks ago which runs during pre-mount and basically performs this steps: - If 99% of disk capacity is partitioned, exit. - else, expand the partition to full disk without losing data. I'm attaching a tar.gz file, without the extension becasue gmail doesn't like it. I've tested it only with XOs 1.5 and haven't measured time cost.

It's probably good that you need to specify the version in this case
because the API between 0.1 and 1.0 is likely to have changed. This is
because there's no libusb.so symlink.

The strange thing is that in another XO, same build (802), it does find
the
library:
from ctypes.util import find_library
find_library('usb')
'libusb-0.1-so.4'
Both XO have this file in /usr/lib, but the first one won't find it.
Nevertheless, it finds other libraries under /usr/lib.
I've checked /etc/ld.so.conf and it's the same for both XO.
I'm using the same version of libusb and libusb-devel, and they were

Skybluetero: GUI for Airtime.py
Hi everyone, I wanted to share with you this piece of software I wrote last year and have been using here at Ceibal. It's a GUI for Ricardo Carrano's airtime.pyhttp://wiki.laptop.org/go/Wireless_Airtime_Analysis . Extracted from the project's google code sitehttp://code.google.com/p/skybluetero/ : skybluetero analyzes tcpdump or wireshark captures and plots the airtime consumption of the filtered packets (using wireshark expressions). Some of its features: - Plotting results using matplotlib, allows to save the plot as an image. - Multiple plot styles - Save/Load filter expressions - Export results to CSV - *Many, many others to come...* I'm barely maintaining it since it is only used at Ceibal by a couple of colleagues. They've reported a couple of bugs and I fixed them. That's it. Maybe if someone else uses it, I may be able to upgrade it, maybe not. Just wanted to let everyone know that you have this tool if you're analyzing wireless traffic. You can download it herehttp://code.google.com/p/skybluetero/downloads/list . Send me comments, suggestions or bugs if you want. -- Ing. Emiliano Pastorino Plan Ceibal Av.

Swap to SD cards: performance and burnout test
Hi everyone, We're testing how much performance you gain by swapping to an sd card. The first thing we need to do is to compare the performance between a regular XO 1.0 (no swapping) and one which swaps to an SD card. The other thing is to measure how long an SD lasts if used that way. So long, we've only compared two XO by running some activities, but we need some numeric results, or something measurable. Does anyone come out with a possible test? Also, we need to write and erase data as fast as possible to measure the lifetime of the SD card. Is there any tool or a way to write random data to the swap space? We're using a 4GB C6 SD card, assigning 512 Mb for swap. -- Ing. Emiliano Pastorino LATU - Plan Ceibal Av.

Re: OFW Q3A15
There is a way to check the temperature under Linux. It involves the lmsensors package, but I don't know the exact details. Yes, that's what I've been using. The package is lm_sensors, if installed, you just have to type sensors and you get the temperature in ºC. I've already checked that temperature never goes beyond 100ºC, so it is working. But how does it work? Is it just underclocking? I've checked /proc/cpuinfo, but clock is always at ~1GHz -- Ing. Emiliano Pastorino LATU - Plan Ceibal Av.

Software-disabling touchpad
Hi, everyone I'm working on accessibility and disabling the touchpad is necessary for kids who can't control their movements and need other input devices. I played a little bit around /sys/class/... and /sys/devices/... and found that with this command: echo 0 /sys/devices/platform/i8042/serio1/pwred you get echo: write error: Operation not permitted, but still the touchpad is disabled. Keyboard still works and I can plug a regular usb mouse. The thing is I can't reactivate it until I reboot the XO. I just wanted to know if this behaviour is normal or it's a bug and I'm not supposed to be able to disable the touchpad. If that's the case, is there a neater way to do that?

Problems compiling bluetooth module
Hi everyone! I have a USB Bluetooth adapter and I need to make it work on an XO. Don't want to recompile the whole kernel but to compile only the kernel module. I've never done this, so maybe I'm missing something... The module I'm trying to compile is btusb (I hope this is the one I need). I'm using kernel 2.6.25-20090223.1.olpc.69098d87d56945c, so I got the corresponding src.rpm from http://dev.laptop.org/~dilinger/testing/ . I've also installed kernel-devel, kernel-headers, gcc, glibc, glibc-devel, glibc-headers and make in my XO (maybe I forgot others). I moved to /usr/src/redhat/SOURCES/linux-2.6.25/drivers/bluetooth and edited Makefile so it looks like this: obj-m := btusb.o KDIR := /lib/modules/$(shell uname -r)/build PWD := $(shell pwd) default: $(MAKE) -C $(KDIR) M=$(PWD) modules Then I ran make but I get 5 warnings about functions which aren't defined: hci_recv_fragment, hci_register_dev, hci_alloc_dev, hci_free_dev and hci_unregister_dev. Those functions are defined in /usr/src/kernels/2.6.25/include/net/bluetooth/hci_core.h I've successfully compiled the module in my desktop PC, but it won't compile in my XO. Actually, it does compile, but when I run insmod btusb.ko it gives an error about the above symbols being undefined. Any tips? Am I missing something like defining a path? Thanks!

Re: Battery recovery issues
Here's the logfile. Just one observation: it tooked me 3:30 h to discharge the battery (I did a bat-recover for 16 hours previously), so the battery seems to be in good shape, and also the XO, since with other batteries the led and output from all these commands behave as expected. Also, I want you to know that the first 20 batteries I tested weren't faulty, they just needed to be charged (trickle charged at the begining, then normal charged). I think that kids and our technicians don't know what does the 4-times-blinking-orange-led mean, so I'm giving them immediate instructions on how to proceed.

Turns out the way I did the disk devices won't work unless you either: 1) boot with a usb drive plugged in 2) run 'p2' before bat-debug-log 'p2' will re-probe usb devices. If the first column is battery's charge, then it's almost dry. Should I try bat-recover or charge it the usual way? The first column is the ACR reading and you can't tell anything by just 1 reading. You have to know what it was when you started discharging or charging. I don't report SOC in that listing cause generally I don't care. I want to know what it does after I turn on charge rather than what level it was at previously. bat-charge simply enables charging and then starts reading the battery directly. Thus it does not care about any of the settings in the EEPROM. Its a good diag tool to see if the battery just physically won't take charge or if you just can't communicate to it at all. If bat-charge works but normal charging does not then its EC or EEPROM badness. The LFP batteries have an overvoltage cutoff that will protect them so its ok to just turn one on and leave it. For NiMH you would end up reducing its life. But since you don't have any NiMH you don't care. 'bat-recover' works by PWMing the charge pin to keep the charge current very low and allow the cells to equalize yet not trip the over voltage like they would if you just turned on the charge and left it. The settings I've picked by default seem to work in most cases but I've had many batteries where I needed to reduce the current even further from the default settings. To speed up the process you can use normal charging methods to get the battery close to full (or wherever it cuts out at) That way the recover process will be much shorter. I'll try bat-recover with a bunch of batteries today, so maybe tomorrow or on Wednesday I'll be sending you some logs, if it is ok to you. After looking at your bat-debug log I've realize that the extra diagnostic info is only present in f-series firmwares with my newer EC code. I'm forwarding you an e-mail with a copy of q2f02 that I worked on while trying to solve some problems with batteries in another deployment. q2f02 will be behind q2e41 in terms of OFW but has EC code with extra battery diag info. For battery testing there should no difference between the 2. Its also available here: (Just never announced since a new e-series release happened right after) http://dev.laptop.org/pub/firmware/q2f02/ So install f02 on your test laptop and re-run bat-debug-log after you have first run 'p2' and the logging to disk should work. I don't need any more see-bstate info. so the steps: install f02 remove battery boot stop at ok insert usb drive (or boot with it inserted) run 'p2' run 'bat-debug-log' insert battery run for a couple of minutes then hit a key send me the log. I'll try to get a f03 out soon with the latest of everything but I've got gen 1.5 bring up tasks that I need to attend to. -- Richard Smith rich...@laptop.org One Laptop Per Child -- Ing.

There is one more battery debugging tool available. Its called bat-debug and bat-debug-log.with the power for the cpu and for the The both read the same thing but bat-debug-log will write the contents to 'disk:\batdbug.log'. 'disk' is USB or SD depending on what you have inserted. bat-debug just does the screen and serial port. If the 1-wire state machine is just looping over and over bat-debug won't provide much more info. It might however point out what part of the state machine is failing. That part of the code has a pretty large number of if() clauses all lumped into the same state. Procedure: 1) Remove the problem battery. 2) Boot machine and stop boot at OFW prompt. 3) run bat-debug (or bat-debug-log) 4) insert the battery 5) let it run for one or 2 screenfuls of info 6) hit a key to stop bat-debug send me the info. Note, that you don't run batman-start before you run bat-debug since you want the EC state machine to run and you don't need to 'fload batman.fth'. bat-debug should be in your firmware already. What is the difference between batman's bat-charge and watch-battery? Tell me if I'm wrong, but I think that bat-charge reads battery info directly from it, and watch-battery takes that info from the EC. So, the problem could be that the EC isn't synced with the battery. Am I right? Correct. Batman code takes over the 1-wire communication bus from the EC and talks directly to the battery. 'watch-battery' uses EC commands to read what the EC thinks. So if the EC state machine is bailing out for some reason then you will get odd things from watch-battery where batman only needs the 1-wire to work. So long I could recover 2 batteries out of 4. I'll try more batteries, the batteries that seem to be ok now are the same model (GP NTA2490), and the other two (the ones I couldn't recover even with bat-recover) are BYD LP183662AR-2S. I have no idea what this number is. The serial number I would need is the long string of digits under the barcode in the center of the battery. If you want me to do a particular test with any of these batteries, just ask and I'll share my results with you. Well. I'd like to make sure the firmware has the diagnostics that will allow you to figure out whats up with the battery. So depending on what see-bstate and bat-debug info is I'll perhaps need to make new firmware or new diags in batman.fth to try and figure out whats up. -- Richard Smith rich...@laptop.org One Laptop Per Child -- Ing.

nandblaster: can't open fs.plc for reading
Hi everyone! We're doing some tests with firmware q2e24 but we're having trouble when trying to serve an unsigned build. As it says at http://wiki.laptop.org/go/Multicast_NAND_FLASH_Update , we need an fs.plc file, but we don't know how to generate it. Any tips? -- Emiliano Pastorino LATU - Plan Ceibal Av.

Judging by the description on the afformentioned page, the fs.plc file has the format described at http://wiki.laptop.org/go/OFW_NAND_FLASH_Updater It is basically a script used by OFW during the update process to build any partitions on the NAND and to validate the eblocks. The bulk of the script is a bunch of sha256 digests for each 128KiB piece (erase-block, or eblock) of the image you're flashing. You can see such scripts by unzipping an fs.zip from one of our signed builds and examining the file data.img. Any tips? Ironically I just built a simple script to generate such files because it will help us in getting your custom images ready for secure reflash. Instructions regarding that process will be forthcoming this afternoon. In the meantime I suspect you can resolve the NANDBlaster issue by using the script. You can obtain the script from: git-clone git://dev.laptop.org/users/erik/image-digestor Run it as follows against the image file you are trying to NANDBlast: image-digestor.sh image_file_name After a minute or so it will produce a file called image_file_name.ofw_update_script. Rename this file fs.plc, put it on the USB alongside fs.img, and start the NANDBlaster again by following the instructions on the Multicast NAND Updater page. Hopefully that resolves the issue.

Workaround for #8155? (hard links in datastore for storing duplicate files)
Hi, everyone. We would like to create a collection of books in pdf format (collection as in http://wiki.laptop.org/go/Collections) for kids in Uruguay, but we've seen that each time you open a book, a duplicate is created in datastore, despite the file being stored locally. That happens in build 656, but I've tried the same in 767, and duplicates are still being created. I've found that ticket #8155 describes this defect, but it seems that there hasn't been any advance since it was created 7 weeks ago. We need to solve this asap, so any workaround is good for us (it doesn't need to be pretty at all). Cheers -- Emiliano Pastorino LATU - Plan Ceibal Av.

Re: [sugar] Display warnings in sugar
Thanks for all your answers. The thing is we're having some trouble here in Uruguay with xos that run out of disk space. Kids download lots of activities, take lots of pictures and videos and they manage to use all free space they have. When that happens, it seems that sugar won't load in some cases or takes too long to do it. That's why we want to give some kind of warning when they have used, I don't know, 95% of disk space or so, so they can delete some stuff before everything crashes. We'll try to figure out something, but help will be appreciated! On Thu, Jul 17, 2008 at 6:21 AM, Tomeu Vizoso [EMAIL PROTECTED] wrote: On Thu, Jul 17, 2008 at 2:27 AM, C.

This is going to be handled by the notification system, which is in its infancy in the upcoming 8.2 release, but should mature and I hope our alert system will use the freedesktop.org standard: http://www.galago-project.org/specs/notification/index.php It is widely used in Gnome, and when I last reviewed it seems to be a solid and capable spec. I believe that was the plan of record in previous conversations; I hope I'm not mistaken. What we have implemented now is some basic notifications generated and consumed in the shell, so we haven't added any public API for now. The interfaces in that spec look quite good, although perhaps would benefit from a simpler, alternative API that also abstracts the D-Bus stuff. Perhaps rainbow should do some rate limiting or permissions checking, not sure.

Re: [sugar] Display warnings in sugar
Thanks, Michael! I was just trying that, but I was missing the XAUTHORITY variable. I think that's going to do the job by now.

Install a cronjob that runs every few minutes. 2. When it runs, it should check the available space. 3. If it concludes that space is low, pop up a warning. Warnings can be simple X or pygtk programs (see the 'dialog' Linux scripts for ideas). To get this hooked up to the running X display, you'll need to set some environment variables: DISPLAY=:0 XAUTHORITY=/home/olpc/.Xauthority Ask if you need more help.

Re: Activation problems

Javascript not working right on Web activity
Hi everyone! We're having problems here in Uruguay with Web activity. Kids can't upload images to their blogs at www.blogger.com or send mails using their accounts at www.adinet.com.uy. Both sites (and plenty more) use javascript for its user interface, but last versions of Web activity won't show some buttons on those sites. We know that previous versions don't have such issues, so we need to fix that ASAP. Who shall I contact to help us with this problem? Or if anyone knows how to solve it quicly, please let us know!
