Create Meego rootfs using Ubuntu Lucid

Francisco Keppler Silva Alecrim — Thu, 20 May 2010 15:44:29 +0000

This week I took some time playing with Meego distro. I got a D510MO motherbord with Atom processor to put Meego working on it. It wasn’t a hard work regarding Meego already contain a X86 repository. Last Meego release was from March 31st but they have a repository contain more recent packages. So I created a new image with most recent packages. I faced some problems to create Meego image using Ubuntu and notes about my experience with Meego are available on my wiki page.

Palestra – Uninorte – Introdução desenv. mov. Nokia usando Linux

Francisco Keppler Silva Alecrim — Fri, 16 Apr 2010 16:26:04 +0000

Ontem estive na Uninorte falando sobre o desenvolvimento para dispositivos móveis da Nokia usando Linux. Este foi o maior público para o qual já palestrei. Acredito que mais de 200 600 300 pessoas estavam no evento. Muito bom este tipo de evento interno com o objetivo de promover a integração entre os alunos de redes da Uninorte. Acho sensacional o fato do departamento de computação estimular a utilização de SW livre por meio de palestras e eventos.

APRESENTAÇÃO DISPONÍVEL AQUI!

Na próxima semana teremos outro evento na Uninorte, o FLISOL!

O FLISOL é aberto para o público em geral e as inscrições já estão abertas!

Você que quer conhece mais sobre SW livre? Resposta: SIIIIIIIMMMM !!!

Quer instalar Linux no seu laptop, mas não se sente muito confortável? Resposta: SIIIIIIIMMMM !!!

Este evento é para você! FLISOL!

N810/N800 + Linux 2.6.33 + Ubuntu Karmic (ubuntu-minimal)

Francisco Keppler Silva Alecrim — Sat, 27 Feb 2010 21:02:20 +0000

This week I got Ubuntu Karmic(ubuntu-minimal) working on N810/N800 with Linux kernel version 2.6.33. Serial, USB(g_ether) and flash memory are working fine with this version. It’s enough to use console over SSH and test some terminal applications. But it’s going to take time to get it working fully on n8x0 like linux-omap 2.6.29.

—————–

$ ssh ubuntu@10.0.1.10
ubuntu@10.0.1.10′s password:
Linux n810 2.6.33-rc8-07939-g4fe94ed-dirty #149 Fri Feb 26 14:58:22 AMT 2010 armv6l
…
ubuntu@n810:~$ cat /proc/cpuinfo | grep Hardware
Hardware : Nokia N810
ubuntu@n810:~$ uname -a
Linux n810 2.6.33-rc8-07939-g4fe94ed-dirty #149 Fri Feb 26 14:58:22 AMT 2010 armv6l GNU/Linux
ubuntu@n810:~$ cat /etc/issue.net
Ubuntu 9.10

—————–

You can download images:

* linux 2.6.33 to n800/n810

* ubuntu karmic minimal image (just console over SSH)

* howto to create your own images

* patches, pkgs and etc

Some notes about Linux 2.6.33 with n8x0:

* Some corrections are necessary to get USB working.

* My kernel configuration define g_ether(USB gadget ethernet) as built-in(CONFIG_USB_ETH=y).

* initfs is not necessary. My kernel configuration changed to bootup directly by flash memory(CONFIG_CMDLINE=”root=1f04 rootfstype=jffs2 console=ttyS2,115200n8″).

* My personal linux-omap tree is available at gitorious

Some notes about ubuntu Karmic with n8x0:

* Generated using rootstock

* Correction to apt works correctly with JFFS2

* Workaround to startup USB interface(IP 10.0.1.10) automatically using udev

* Using openssh-client/server instead of dropbear(lightweight). Dropbear install fails

PS:
* Thanks to Stskeeps, luke-jr from #mer at irc.freenode.net !

* rbelem, post done. enjoy it! http://www.rbelem.info/

* Doubts, questions or comments? Post it here or use #ubuntu-arm at irc.freenode.net

Sync Evolution and N95

Francisco Keppler Silva Alecrim — Sun, 04 Jan 2009 06:54:17 +0000

A few days ago I synchronized Evolution with my N95 phone. It was possible because I found a tutorial/post from Ubuntu Forum that helped me a lot.

Thanks to HyRax!
