See you there!

We’re working with Qt Kinetic at INdT. Mamona, as our platform, should support it. 

Question: Do you want to test on your device?

Answer: You can follow this tutorial HERE.

The video below demonstrates Infoshare feature in Carman 0.7 beta 2:

Main difference to beta 2:

  * Infoshare feature does not need Pidgin anymore
  * Carman supports up to 4 connected buddies
  * Jabber/MSN/Yahoo are the supported protocols
  * Infoshare daemon: infosharingd handles all communication between Carman
    and libpurple, using DBus.
  * A lot of improvements in carman-evas code

Thanks Carman team !

Nice days at Porto de Galinhas with good presentations and a great opportunity to share open source experiences. That was Bossa Conference 2009!

You can see some presentations posted by Bossa guys and great pictures posted at Marcelo’s flickr.

I’m still waiting for new posts at http://openbossa.blip.tv/ with presentations from Koen, Kate and Barbieri.

Yesterday I tested the open source WLAN driver stlc45xx developed by Kalle Valo and community.

First I tested it with Maemo using a simple open wlan network and it works fine.

The problems that I faced:

* Missing tools
You will need some tools that does not came with the original image. Some extra packages installed(wireless-tools dropbear-server libicd-network-dummy dropbear-scp) using an extra repositories. I installed the packages with default Maemo kernel(2.6.21-omap1) to have access to internet during the installing of preview packages.

* RD flags did not work properly
Using all flags defined by README the device turn off without any output or error message. I used the “flags no-omap-wd, no-lifeguard-reset” as Briglia and it works.

* Navegate using Maemo browser
Maemo does not recognize the WLAN interface and I’m not able to select a network using the UI. So I connected to network using Xterm, but anyway I was not able to navegate using MaemoBrowser. It was necessary to create a DUMMY connection say the Maemo ICD that network is available.

I did some notes and it’s available on my wiki page.

Bossa is gonne be a great opportunity to share experience related to Open Source and Embedded development.

I selected some presentations that I won’t miss.

* Koen Koin - Multimedia and OMAP CPUs

* Marcel Holtmann - New NM for Embedded Linux systems

* Kate Alhola - Maemo 5 (freemantle)

I’ll see you there!

I have a N810 and 3 OS in the same device.

Now you will ask me : How?

The answer is below:

1 - Move your Maemo to the MMC internal

* Advantage : you will have more space.

Steps:  http://maemo.org/community/wiki/HowTo_EASILY_Boot_From_MMC_card/

Now you have the Maemo in the internal MMC.

2 -  Flash Mamona in your flash memory

* Advantage: Nowadays Mamona distro is good for developers.

Steps:  http://dev.openbossa.org/trac/mamona/wiki/Releases/0.1/RunningMamona

3 - Debian XFCE in external MMC

* Advantage:  Debian rocks !!

You should partition your MicroSD in 2 parts:

- partition 1 - 100MB - fat32

- partition 2 - ALL THE REST - ext2

Download the Debian rootfs

wget  http://debian.i2c3.com/debian-armel-n800-xfce-beta3.tar.bz2

Untar the Debian rootfs in the second partition:

tar -xvjf  debian-armel-n800-xfce-beta3.tar.bz2

Boot using your external MMC.

That’s all!!

Hi all,

+

I tested SDIO GPS with a OMAP1710 and it works. Many phones and internet tablets are based on this platform. The steps below show the procedures I’ve done:

== KERNEL SIDE ==

Compile a new kernel from linux-omap with some additional features activated.

Device Drivers  ---><*> MMC/SD card support  --->   SDIO UART/GPS class support

Boot your device with this feature.

Maemo-omap1710:~# modprobe sdio_uart

Plug your SDIO card and the message below will be printed.

mmc_slot (GPIO 193) is now openmmci-omap mmci-omap.1: cover is now closedmmci-omap mmci-omap.1: command timeout (CMD8)mmc0: new SDIO card at address f111

The entry /dev/ttySDIO0 should be created.

== USER SIDE ==

I’m using GPSd to test it. Download the last version, compile and install on my device using scratchbox.

Start the GPS daemon

Maemo-omap1710:~# gpsd -N -n -D 2 /dev/ttySDIO0 &Maemo-omap1710:~# gpsd: launching (Version 2.34)gpsd: listening on port 2947gpsd: running with effective group ID 0gpsd: running with effective user ID 0gpsd: opening GPS data source at '/dev/ttySDIO0'gpsd: speed 4800, 8N1gpsd: garmin_gps not active.gpsd: gpsd_activate(1): opened GPS (4)gpsd: SiRF packet seen when NMEA expected.gpsd: FV  0x06: Firmware version: MEW-05-00-030627Wgpsd: FV  0x06: Firmware version: 2.4.02.02 0800003f21

The filesystem used is based on Maemo.

Hi all,

Maemo gave me a discount to buy a N810 and soon I’ll do some test using the tool that I based my final project (SOM-IA + MAEMO + MEMORY).

Regards,

Alecrim.

Hi all ,
Last week,I was doing my final project and using an interesting tool,called Xautomation ( http://hoopajoo.net/projects/xautomation.html ). I’m using a Nokia 770 to do some test and this tool is very important to automate my test.It is already available on x86,I packaged for ARMEL.It is avaliable on my web page under construction. I tested on N800 and it works.

Xautomation ARMEL Debian package :

http://extindt01.indt.org/keppler/

PS : I will talk about my final project in few days.
