The Fedora ARM team can probably help you.
Send an email to their list

Re: Is gabble not working correctly?

[rihowa...@gmail.com]

Jerry,

I had been meaning to send an email regarding this and file a bug report. 
With 13.1.0 build 22, and possibly earlier builds, I cannot make a connection 
to an XS.
(I use Anna's XS for testing). I see this with both an XO-1 and and an XO 1.75 
running 13.1.0

If I have both XOs running 13.1.0 booted they connect directly to each other.
Running olpc-netstatus indicates they are not connecting to the school server

I can connect to the XS using 12.1.0 with both an XO-1 and an XO 1.75.

Re: ARM motherboards

[rihowa...@gmail.com]

Sameer,

I see you already found a mention of MPICH2 .  Coincidentally  was going 
suggest this coming Saturday as something to demonstrate at OLPC-SF.
http://www.mcs.anl.gov/research/projects/mpich2/

http://www.mcs.anl.gov/research/projects/mpich2/documentation/files/mpich2-1.4.1-installguide.pdf

I know it is outside the scope of OLPC but it would be interesting to see what 
this type of message passing interface could do on a group of XOs.

Re: Epiphany issues XO 1.0 build 20 12.1.0

[rihowa...@gmail.com]

I can confirm what you are seeing with build 20 12.1.0 and Browse and asking 
for a developer key.
By the way the OFW I have is Q2F12.

At least with this version of Browse hml5test.com displays without crashing.

The http://wiki.laptop.org/go/12.1.0#XO-1 needs to be updated to reflect the
 move back to jffs for the XO-1 and the method for installing.  
OFW help on XO-1 may need to be changed to reflect this.

Re: 12.1.0 devel build 5 released, for the XO-1, XO-1.5 and XO-1.75

[rihowa...@gmail.com]

Tried this build with an XO-1 and it boots OK.

It can connect to my wireless router.

Frame key does not invoke the Sugar Frame.

It try to use Browse to open a page, for example www.google.com, opens but then 
crashes straight away.
Note that I ran software update form the Control Panel and it claim to update 
Browse from 133 to 134 but still showed 133 in the list view

Running ping in the Terminal activity returns:
 "ping: icmp open socket: Operation not permitted"

SDHC card in the XO-1's slot is not auto-mounted. 
USB drive is not auto-mounted.

I have not tried any other activities or gnome.

If I download the file from http://dev.laptop.org/pub/firmware/q2e48/q2e48.rom
and on an unlocked XO1 use the OFW command 
flash u:\q2e48.rom

I get :

Reading u:\q2e48.rom
Image file is the wrong length
ok

Re: [Sugar-devel] Potential volunteer offering technical writing

[rihowa...@gmail.com]

I think what was used to generate the help was the FLOSS Manuals Remix feature, 
http://en.flossmanuals.net/index.php?plugin=remix .
The workflow would be to identify the source of the existing help text starting 
with the Sugar and XO books. 
Edit the source material then use the remix feature.
I would suggest saving the original books to preserve those editions for people 
still using older versions of the software.

Re: Technical session suggestions for OLPC SF summit

[rihowa...@gmail.com]

Daniel,

We had a brain storming session at the last OLPC-SF Community Summit 2011 
planning meeting ( http://olpcsf.org/summit ) and came up with 
http://wiki.laptop.org/go/OLPC_SanFranciscoBayArea/OLPCSF_Community_Summit_2011#Suggested_Topics
 .  Feel free to add to that list. The list is not final.  We will be setting 
up the schedule in the next few weeks, so now is the time for suggestions. 

Bernie was in the area and came to the meeting and indicated he may speak at 
the Summit.  Maybe you could coordinate topics with him?

ARM: new cross-distro@ list

[rihowa...@gmail.com]

I am forwarding this on behalf of Steve McIntyre 

=

Hi folks,

Many GNU/Linux distributions are doing some ARM porting; this tends to
result in work duplication, and there doesn't seem to be a general
purpose forum to bring ARM porters together.

We're inviting developers of GNU/Linux distributions with an interest
in ARM to join a new "cross-distro" list, hosted at Linaro:

  http://lists.linaro.org/mailman/listinfo/cross-distro

Any ARM Linux / Free Software discussion is welcome on the list, for
instance porting software to build on ARM, toolchain problems, dealing
with new ABIs, Thumb-2, NEON, kernel problems, announcement of new
tools etc.

Cheers,
--

Re: os351 on XO-1 - Browse & memory pressure

[rihowa...@gmail.com]

I just booted up my XO-1 running Dextrose os4dx2 in Sugar mode.
I revealed the frame and waited until the System Resources gauge had a happy 
face ;)
I started Browse. While starting the System Resources gauge pegged at 100% CPU 
and Memory in use 38%
Once Browse was fully launched the gauge indicated 8% CPU use and Memory n use 
40%. ( Steve - Cute icons in the gauge by the way ).

By the way while in gnome mode with this Dextrose build I managed to run 'yum 
install gajim' from terminal session. It ran slowly but I had a couple of other 
applications running.  I think the larger tmpfs helped yum run.  I had tried 
this previously with 10.1.2, but yum would crash even if run with no other 
applications running.

Re: spectacular new XO-1.5 disassembly guides

[rihowa...@gmail.com]

Holt,

Nice set of photographs and narrative.
It might be useful to mention at the top of the document the type and number of 
screws.  At each step where a screw is removed or replaced that type and size 
of screw should be called out. 
Where it mentions cable disconnection and cable connection it should mention 
the type of latching mechanism used and how to manipulate it.

Page numbers would be useful as would a document revision identifier

Re: [Server-devel] Observations and question about http://wiki.laptop.org/go/XS_Software_Repositories

[rihowa...@gmail.com]

Martin,

It would make more sense for me to base this effort on F11 XS code even if it 
is experimental.  This will help find hardware dependencies in the code.
Is this the location you are referring to for the F11 XS 
http://fedora.laptop.org/xs/testing/olpc/11/source/SOURCES/ ?  If so I would 
rather clone from source control system so it is easier to give you any diffs 
back.
I know in the earlier versions of XS software there were a number of places 
that the arch was hard coded to an X86 variants.

I just noticed that the  http://wiki.laptop.org/go/F11_for_XO-1 page has not

Is this intentional?

By the way thank you for the builds.

You are correct.  Android development is Java based.  It is based on a subset 
of Java functionality with the android API built on top of that.

If you want a QT based environment look at Meego http://meego.com/developers.

Mikus,

There is also problems with turning the radio on and off in sugar control panel.

As Steve Parrish has said he needs help as he has little time in the day to 
work on X11 for XO1.

Re: New release of F11 for the XO-1 - Build11

[rihowa...@gmail.com]

Sameer,

The fix is not in build 11.
I am resending the contents of the email minus the observation about midori, 
(as mention of midori seems to make the boys want to play with the bike shed 
instead of concentrating on the important tasks).  ;)

"Some quick observations on  F11 for the XO-1 - Build11.

I have applied the "Virtual 1200 900" fix from 
http://dev.laptop.org/ticket/9590 and the screen rotate button now works in 
both Sugar an Gnome.

Sugar Desktop mode:
I found with this build if I turn off  the Radio from the control panel I can 
not get it to turn back on.  Also the wording is confusing. It is unclear 
whether have the check box checked or unchecked turns off the radio.

The Record activity did not open correctly. It would exit immediately, until I 
applied the "Virtual 1200 900" fix to Xorg.conf 
With the  "Virtual 1200 900" fix applied Record will now open and I can take a 
photo and record a video. 
The video is very pixelated in Low mode though, and in High mode and Best mode 
Record video seems to only produce a still with some sound. 
Record's audio only mode does not seem to record sound.

Gnome Desktop mode:
I can turn the radio back on through Net Work Manager in Gnome.  This is after 
the radio is turned off in sugar where I cannot then turn it back on.  So the 
work around is to go into gnome and turn the radio back on.
I have not tried any Gnome applications that use a camera to see if it now 
works in Gnome

Firefox

Re: Mentor request for PyDebug Activity

George,

I am curious why start on a new activity? The Develop activity is  
well along and needs bug fixing and updating.  A debugger would be a  
nice addition to it.

I am excited about developing a tool to help me develop other XO  
Activities.  When I shared my ideas with Adam Holt, he suggested  
that I seek a mentor, or a few partners to help me clarify my  
ideas, and increase the usefulness of the end product.   I am  
writing this to request such help.


As a programmer, I'm fairly new to python.  I started writing  
assembly language in 1975 for the terminal division of Hewlett-- 
Packard, which was soon to become the Personal Computer division.   
I only started python after I got my G1G1 in early 2008.


I'm fairly averse to re-inventing the wheel.  So I have been  
thinking of combining Activities that already run on the XO as my  
main strategy.


At this point I have hacked together Write, Terminal, and  Browse  
to all exist in a notebook under the Sugar toolbar.  I can read and  
write Activity.xo files from the journal.  So I've learned a lot  
from what is already written.  Whatever the final form factor, the  
work I've done up to now will not be lost.


At this point I'm debating whether to substitute gedit for the  
functionality of abiword.  Gedit includes many of the feature a  
programmer is looking for. It is extensively internationalized. It  
has a  python extension system that I think will make for easy  
integration into my application.


I'm leaning towards the structure of a remote debugger, even though  
the client and server will mostly reside on the same machine.  I'd  
like for the application to be insulated from errant client programs.


I'm having a lot of fun, and feeling much more productive than I  
did a few months ago.


I'd love to hear from a few people who are willing to help me  
perfect my ideas or have experience that could keep me from going  
down unfruitful paths. I've written a wiki page trying to pull  
together some of my ideas: http://wiki.laptop.org/go/ 
Python_Debugger_activity_for_the_XO.  There is also a little more  
bio info about me at http://wiki.laptop.org/go/User:GeorgeHuntd

Re: new F11-for-XO1 images available for testing

[rihowa...@gmail.com]

Daniel that is interesting.

My arm devices are booting directly on ubifs. One is running ubuntu  
( SheevaPlug ) and the other Fed 8 ( OpenRD Client). I am going to  
build Fed 11 this weekend for the OpenRD Client and then try and get  
the XS bits ported to it (but that is for a separate thread with  
Martin L.)

These devices use a special build of u-boot from Marvell to initiate  
the boot.

Wish I knew how to create drivers for OFW so it could boot from UBIFS.

Re: new F11-for-XO1 images available for testing

[rihowa...@gmail.com]

Any thoughts on moving from jffs to ubifs ?
Seems like ubifs has really improved in stability recently.

I have been playing with some ARM based devices, using a recent  
kernel, and went from jffs to ubifs and the file access and boot  
performance improved enormously.
Should hopefully see the same thing with the XO-1.

OLPC repository problems causing yum to time out

[rihowa...@gmail.com]

I was helping an XO user to resolve a problem with yum failing on her  
system.
After trying it on my XO I discovered that the OLPC  repositories are  
not responding. Hence yum errors out with a  timeout.
I can fix this for he,r but that leaves the problem out there for all  
the hundreds of thousand other XOs.
 Is this just a temporary outage?  If not could a dummy responder be  
set up to prevent the yum time out, as this is a difficult problem  
for naive users to deal with.

Re: [Testing] Wireless test results

[rihowa...@gmail.com]

I find 767,  with either q2e18 or q2e24, connecting to a WPA AP  
succeeds 100% of the time for me using a Linksys WRT54g L.

  With OFW q2e32 I have seen the network connection die. Seems like  
the stack is dead.  I assume it is the marvell driver that is  
delivered with q2e32.  My other XO running 767 with q2e18 maintains  
its connectivity.

Re: OLPC upgrades

Those software gauges tell you what ever 'version of the truth' the  
author wants to tell you and make you feel happy about your device.
To perform power measurements reliably you need to instrument with a  
good quality physical voltmeter and ammeter.

I was exhausted that day.  Finally took some vacation time after that  
and
caught up on my sleep ;)  Anyway what do you say to a 7 year old that
  wants to help?  You do not say no, you say yes and encourage them.
  That is how to help develop inquisitiveness and volunteerism.

Re: XOs with no sound

[rihowa...@gmail.com]

I have seen this problem when the alsamixer settings have become  
messed up.  Seems like there are one or 2 processes that occasionally  
write to the alsamixer config file.

You can alter the settings by running the graphical program /usr/bin/ 
alsamixer  from the terminal.  There is also a command line program / 
usr/sbin/alsactl but being late at night I can't remember the syntax  
off hand.

Mildred,

In the Control Panel, select Network and then in the Mesh server  
field put the server name.

Chat is a jabber client.
Also other people have gajim and or pidgin running okay and no  
problem with saving configuration.
