[Announcement] Sugarizer v0.5 is available for your device


Hi all,

 

I'm proud to announce the fifth version (0.5) of Sugarizer, a taste of Sugar for any device.

 

http://sugarizer.org

 

I've decided to put the focus on this version on three majors points:

  • Responsive Design: to ensure that Sugarizer could work on any screen size, from the smallest smartphone screen (320x480) to the bigger tablet screen (2560x1600).
  • Android support: I've done a huge work to ensure that Sugarizer and activities work well on Android so I've fixed lot of issues related to Android limitation. Of course due to diversity of the Android ecosystem, some issues could still exist on Android versions lower than 4.2.
  • Firefox OS support: Thanks to Mozilla foundation that help me on that, Firefox and Firefox OS are now #1 platforms for Sugarizer. Sugarizer has been tested successfully on Firefox browser and on several Firefox OS devices (Keon, Peak, Flame).

 

Finally, because it's very important for us that Sugar/Sugarizer could be accessible to every users, I've packaged and published Sugarizer on three major app stores:

Of course, you could also install it by yourself using instructions on the Sugarizer website if you don't like stores.

 

Other features of this version:

  • Updated TurtleJS version, now save automatically context in the Journal
  • Updated Gears version, now use colors for gears
  • New Etoys activity (beta)
  • Favorites activities are now saved in user settings (so, could be retrieved from a device to another)
  • Favorites activities are now configurable at server settings
  • German localization

 

Do not hesitate to fork and contribute: I need you to Sugarize the world !

All contributors are welcome.

 

               Lionel.

 

P.S.: Special thanks for their contribution on this version to: Jorge Alberto Gómez López (TurtleJS activity), Manuel Quiñones (Gears activity), Bert Freudenberg (Etoys activity), Christian Stroetmann (German localization), Jason Weathersby (Firefox OS support).

Hi James, OLPC community,


I'm looking to be able to run a forth script in secured laptops in the Peru deployment. I'm the buildmaster for the current production image, and hold the crypto keys necessary.

Please point me to some docs or simple procedure off the top of your head, if you have it.

Also, Is there perhaps forth code available for a simple, nice menu?

Thanks in advance,

Status of marvell-ipp

Dear all,

I'm the maintainer of a small desktop Linux OS (FatdogArm) which runs on many ARM platforms including OLPC
XO-1.75 and XO-4; together with Yioryos we released support for OLPC late last year. 

I have recently looked at video playback acceleration and have successfully managed to get it going for
other platforms, so I'm thinking to do so on OLPC as well. Before I start, though, I'd like to ask you about
the status of marvell-ipp (http://wiki.laptop.org/go/Vmeta) as of today? 

I checked the OLPC git repos and rpmdropbox and I can't get the marvel-ipp binaries there. I can actually
find these  binaries by doing google search (and the binaries were clearly marked for OLPC usage) but I
would rather be in the clear when it comes to licensing - are these licensed to OLPC so that they can be used in
any OS that runs on the XOs, or are the license more restricted than that? (ie: no license at all, license per
region, official OLPC OS only, etc, etc). If it is licensed freely, then is there an official location
where I can get this binaries? 

Thank you.

end of a XO-1

I hope this isn't completely off topic for this list. My idea is that
posting this report here might be useful to someone in the future
searching for related information.

Back in 2008 I bricked my XO-1 B2 (128MB) machine by upgrading to a
firmware that was incompatible with it. The original firmware didn't
have the commands needed to boot SqueakNOS and I wanted to play with
that system. I downloaded the needed software (spiflash.dic) and
firmware (q2c27.rom) to fix the problem and opened up the machine. The
serial connector CN24 was missing, but I made a five wire cable from an
old floppy cable and my brother-in-law, Fred, carefully soldered the
wires to the missing connector's solder pads on the board. The plan was
to use the IDC connector at the other end of the cable to connect to a
Xilinx ML401 FPGA development board configured as a serial adaptor.

I was using the FPGA board for another project and only got around to
trying to fix the XO-1 last week. The XO-1 was also missing the Recovery
Mode Jumper Block (CN31) so my father taped a small piece of metal
shorting all four solder blobs. I checked that the FPGA was generating
65MHz for the EC chip and using a serial terminal application on the PC
I could see that characters typed on the PC keyboard were reaching CN24
on the laptop.

Plugging in the laptop's power brick (with no batteries) made the
message "213423:SCI:40" appear in the terminal application (the first
number wasn't exactly that and changed a little each time - it was some
kind of time stamp). Unplugging caused a similar message. Eventually I
noticed that pin 1 of CN24 is supposed to be 3.3V from the laptop to the
serial board and not from the serial board like I had thought. I
reconfigured the FPGA to stop sending 3.3V on that pin and now the
message would only appear when plugging in the laptop and random noise
when unplugging.

Pressing the power button generated about five more messages and then a
<cr><lf>"M" heartbeat message every two seconds or so. Running "./forth
spiflash.dic" didn't yield the desired results because the program
thought that 0x0d was the SPI FLASH ID, which was invalid. Trying more
times would get 0x0a, 0x4d and back to 0x0d as IDs, all invalid.

I suspected that the KB3700 was operating in normal mode instead of ISP
(programming) mode. So I removed the metal short from the solder blobs
at CN31 and verified that two of the diagonal pins were ground (I got
about 1 ohm) and the two opposite diagonals were KB3700 pins (about 100
ohms to ground). I expect these would be TP_ISP_MODE (pin 54) and
TP_CLK_TEST (pin 48). Without the short the behavior was exactly the
same as before. We tried to use two screwdrivers instead as short
circuits but couldn't get anything that looked like an ISP mode.

At one point the laptop failed to turn on and the EC chip no longer sent
any messages to the PC. The 12V from the power brick was still good and
the 65MHz from the FPGA board was the same as before. It is very likely
that the EC died, though it could also be some part of the internal
power supply. We unsoldered the cable and closed up the machine. It can
still be a nice static display in some museum.

I can think of two possibilities for the failure to program the ISP
flash. The first is that the EC chip was not in ISP mode. Given how hard
we had to poke the solder blobs with the multimeter probe to see which
ones were supposed to be ground it is likely that there was a layer of
something on top of the blobs (even though they still look shiny) that
was causing bad contacts. The alternative is that the EC wasn't
receiving commands from the PC because of the 65MHz ripple on the RX
line. It looked pretty bad on the oscilloscope (nearly 1V peak to peak)
but serial ports are sometimes surprisingly robust.

Testing 40002au4.zd image on XO-4

Maybe this information is already known.
Played around and found the following:

1. Piano and Write not working.
2. Browse will work but sometime it just kick you out :-(
3. Other connected XO will not show in neighbourhood.
4. Picture taken by record normal but when view from clicking the picture "overexposed when access from the journal.
5. Can't get out to Gnome

XO Keyboards

Hi All

Can anyone suggest where I might be able to get some replacement XO-1 / XO-1.5 keyboard membranes in US keyboard layout please.

Wr have around 20 XOs with missing keytops where the membrane has been damaged in use.

Thanks for any suggestions.

Regards
Terry

Re: [support-gang] Firefox won't install on XO-1/Gnome; other options?


On an xo-1, using the official 12.1 from download.laptop.org as a base, I am able to successfully yum
install firefox with the 2 new dependencies (fedora-bookmarks, xulrunner) and 7 updates - mostly nss*
modules). FF works fine with the Google and Gmail sites.

Easier to make a new XO-1 build using olpc-os-builder that already has
firefox in it, than to deal with all the things that have to be done
to bolt it on later.

‎Firefox has a lot of dependencies, it has to bring the whole xulrunner thing back, so the out of space may
be disk, not memory

Hi,
This is because by default /tmp is only 50mb on XO1.

Yum is a real memory hog.

What I do as a temporal fix is:

mount -o remount,size=200m /tmp

I second James's discouragement of using private lists to give public 
support.

Regards,
Sebastian
