Repository for omap850 ASoC audio driver template

Marek Belisko — Mon, 11 Jan 2010 20:52:55 +0000

Hey guy who wish to have asap audio working on your HTC wings, wizards….

One month before I started to work on porting existing omap850 audio driver to latest kernels ASoC driver.
Currently I have no very much time but I just prepared templates for ASoC audio driver.

Currently when you compile ASoC driver and boot during on WM playing music you can also play music in linux with this template
using aplay, mplayer or whatever.

Current driver consist from more parts. I make a decision to split EAC code to codec dai and cpu dai.
Maybee in future it will be combined again but will see.

You can clone from (using git or http protocol ):

git://github.com/nandra/linux-omap.git

http://github.com/nandra/linux-omap.git

branch is eac_audio.

All contributors and reviewers are WELCOME

How to setup nfs root for HTC development.

Marek Belisko — Wed, 25 Mar 2009 22:02:49 +0000

After 4 hours of collaboration and testing I would like to share how to setup nfs rootfs for speeding up HTC (or whatever) development.I assume you have nfs server installed and running . In below example will be server ip:192.168.2.16 and target ip:192.168.2.15.

1. copy rootfs somewhere to filesystem e.g. /home/user/rootfs

2. export directory in /etc/exports
should look like:
/home/user/rootfs 192.168.2.0/3(rw,sync,no_root_squash,no_subtree_check)

3. restart nfs-server: /etc/init.t/nfsserver restart

4. Server will be connected to target via cdc-ether interface. To avoid problems we need to add
static ip configuration for usb0 interface. I’m running on opensuse for different distros check
manual.
Create new file in : /etc/sysconfig/network/ifcfg-usb0
# USB configuration for HTC phones
BOOTPROTO=’static’
IPADDR=’192.168.2.16′
NETMASK=’255.255.255.0′
NAME=’usb0′
STARTMODE=’hotplug’
USERCONTROL=’no’
BROADCAST=”
ETHTOOL_OPTIONS=”
MTU=”
NETWORK=”
REMOTE_IPADDR=”

5. Add correct kernel command parameters.
set CMDLINE “root=/dev/nfs ip=192.168.2.15 nfsroot=192.168.2.16:/home/user/rootfs ,nfsvers=3″

5. Run Haret and enjoy. That’s all

Note:

I face that problems with Kernel panic – attemp to kill init was caused by non existing /dev/console node. To create new one run sudo mknod /console c 5 1

Hacking HTC Oxygen (HTC 310, SPVC 100)

It’s an one of the first smartphones from HTC. I bought one from my colleague for trying to port linux on it. Currently some work was done on similar models like Typhoon or Tornado (http://vivien.chappelier.free.fr/typhoon/index.html).
I try to get sources from mentioned web page, browse and try to compile kernel for Typhoon model. I was lucky so compilation works for first time without errors.

Next I load image to SD card on phone and with using Haret (http://www.handhelds.org/moin/moin.cgi/HaRET) try to load kernel from winCE. After message jumping to kernel I see only nice variety of colors on display but not recognizable text . Problem could be because of display resolution. Next try will be to adapt existing fb driver for Oxygen TFT display. Trying to search for some specs wasn’t successfull so I try to open device and check producer name or any other clue. So thats the progress. You can find early more infos in new project.
