Installing Navit on the HP H2210 ipaq[edit]

Error creating thumbnail: Unable to save thumbnail to destination
Navit on iPAQ H2210


I tried to build Navit cvs for my HP H2210 ipaq using the OpenEmbedded cross-compile environment. Later i did the same for the Nokia n810.
These notes were made during the process. It's sort of a howto.
It is by no means perfect or complete but shows my progress at this time (may/june 2008) with the issues needing attention. Maybe, by the time you reed this, the issues I found are already fixed, or new ones popped up. Feedback is welcome.

The H2210 is running the Ångström 2007.12 Linux distribution from SD card.
My PC is running Fedora 9 on AMD x86_64.


First read the info from http://wiki.openembedded.net/index.php/Getting_Started
Then set up the build environment with the info from http://www.angstrom-distribution.org/building-angstrom

In build/conf/local.conf add:


In the org.openembedded.stable/packages/navit directory you edit SRC_URI and EXTRA_OECONF in navit_cvs.bb:

 SRC_URI = "svn://navit.svn.sourceforge.net/svnroot/navit/trunk;module=navit;proto=https"
 EXTRA_OECONF = "--disable-binding-python --disable-gui-sdl --disable-samplemap --enable-avoid-float --enable-avoid-unaligned  --disable-binding-dbus --enable-gui-gtk --disable-postgresql --disable-graphics-sdl"

and add in navit_cvs.bb:

 DEPENDS = "gtk+ libglade"

Then in navit.inc, comment out the RRECOMMENDS:

 DESCRIPTION = "Navit is a car navigation system with routing engine."
 DEPENDS = "glib-2.0 gtk+"
 #RRECOMMENDS = "gpsd speechd flite"   <---

If you didn't already, get the dev tree:

 git clone git://git.openembedded.org/openembedded org.openembedded.dev

Copy over dbus-native-1.2.1.bb, dbus-1.2.1 directory and dbus.inc from the org.openembedded.dev tree to the org.openembedded.stable tree.

Edit gmp-native.inc and add:

 LDFLAGS += " -Wl,--allow-multiple-definition "

Then go to the main dir of the build environment (/stuff) and type:

 bitbake navit

The system will be busy for some time.
Drink some coffee...

Meanwhile go to http://www.angstrom-distribution.org/repo/ and get and install flite for your CPU and for Ångström 2007.12. For h2200, the CPU is arm5vte.
Maybe you need more, if so, please let us know.

When the bitbake build is ready, go to the angstrom-tmp/deploy directory to find your packages. Install and configure as described Configuration.

Internal gui on iPAQ H2210

E.g. try the Internal GUI for a graphical menu, fullscreen map, OSD, etc.

Relevant bugs: 4344
4348 Can be ignored as it appears
Also see this email.
Usefull reading: bitbake manual.


Later, september 2009, I found out that one needs automake-native version 1.10.2, so I copied over the automake package directory from .dev to .stable and added


to local.conf.



bitbake 1.8.12 didn't work as well as 1.8.10.


For my build I had to change the plugins block in navit.xml to make the libs found:

       <plugin path="$NAVIT_LIBDIR/*/${NAVIT_LIBPREFIX}lib*.so.*"/>
       <plugin path="$NAVIT_LIBDIR/*/${NAVIT_LIBPREFIX}libgraphics_null.so" active="no" />

Please note the '.*' at the end of the first plugin path. Alternatively you can attempt to install the navit-dev package which has the correct .so links.

Alsa and flite[edit]

I still need some help/info to get flite working standalone; I now get:

 $ flite -t test
 ALSA lib pcm_plug.c:773:(snd_pcm_plug_hw_refine_schange) Unable to find an usable access for '(null)'
 audio_open_alsa: failed to set number of channels to 1. Invalid argument.

System sounds work. Flite doesn't. Stereo audio goes well with aplay, mono gives the error.

First of all need to rename /etc/ssoundrc to /etc/asound.conf.

Further path to a solution:
Add a working mono to stereo thingie to /etc/asound.conf.
Recompile flite with not 'default' as default device but the mono to stereo converter.

The asound.conf that's needed:

 # simple dmix configuration
 pcm.dsp0 {
   type plug
   slave.pcm "dmix"
 ctl.mixer0 {                                                                                        
   type hw                                                                                         
   card 0                                                                                          
   type plug                                                                                           
   slave.pcm "10to20"                                                                                  
 pcm.10to20 {                                                                                        
   type route                                                                                          
   slave.pcm hw:0                                                                                      
   slave.channels 2                                                                                    
   ttable.0.0 1                                                                                        
   ttable.0.1 1

This gives:

But also:

 root@h2200:~$ flite -t test
 ALSA lib pcm_params.c:2152:(snd_pcm_hw_refine_slave) Slave PCM not usable
 audio_open_alsa: failed to get hardware parameters from audio device. Invalid argument

Any ideas on how to fix this or even investigate this?
Wishie has looked into this on #alsa
I also started asking about this on the festlang-talk mailinglist. From interaction with Nickolay I patched the alsa code to flite to force stereo. Then flite starts producing sound but still has issues: internally flite thinks about mono audio while the soundcard is in stereo after my small patch.

I can reproduce the mono thing on the PC. If I build flite there it also decides to produce mono wavs,just as on the ipaq. So there might be something in the alsa patch for flite...
Where does flite decide to produce mono sound?


Below is the local.conf I used, it might be usefull.

 # Where to store sources 
 DL_DIR = "/home/user/downloads" 
 # Which files do we want to parse: 
 BBFILES := "/usr/src/ipaq/org.openembedded.stable/packages/*/*.bb" 
 BBMASK = "" 
 # ccache always overfill $HOME.... 
 # What kind of images do we want? 
 IMAGE_FSTYPES = "jffs2 tar.gz " 
 # Set TMPDIR instead of defaulting it to $pwd/tmp 
 TMPDIR = "/usr/src/ipaq/${DISTRO}-tmp/" 
 # Make use of my SMP box 
 # Set the Distro 
 DISTRO = "angstrom-2007.1" 
 # 'uclibc' or 'glibc' or 'eglibc' 
 #ANGSTROM_MODE = "glibc" 
 MACHINE = "h2200"

Globalsat BC-337 CF GPS[edit]

Error creating thumbnail: Unable to save thumbnail to destination
Navit on iPAQ H2210 w/ Globalsat BC-337

I got me a CF GPS because it would be handy to use while on the move, together with the H2210 ipaq. SD card for Ångström and Navit. CF for the GPS. After inserting the card, dmesg gives me:

 <5>[2414239.760000] pccard: PCMCIA card inserted into slot 0
 <5>[2414239.760000] pcmcia: registering new device pcmcia0.0

Nothing more. Stuff sorta works:

 root@h2200:/boot$ pccardctl status
 Socket 0:
  5.0V 16-bit PC Card
  Subdevice 0 (function 0) [unbound]
 root@h2200:/boot$ pccardctl ident
 Socket 0:
  product info: "CF CARD", "GENERIC", "", ""
  manfid: 0x0279, 0x950b
  function: 2 (serial)

So no driver bound to the card. In #oe I learnt from hrw that i might need this patch. The process then becomes:

 bitbake -c clean virtual/kernel

then apply Koen's patch to defconfig and

 bitbake -cconfigure virtual/kernel

then apply the small kernel patch, and edit 8250.c according to this info to avoid conlicts between serial_cs (8250) and PXA serial device names. Then:

 bitbake virtual/kernel

Install the kernel, and do

ipkg install kernel-module-8250_2.6.21-hh20-r16_h2200.ipk kernel-module-serial-cs_2.6.21-hh20-r16_h2200.ipk.

After installing the kernel and rebooting we now get, when we insert the GPS:

 <5>[  155.760000] pccard: PCMCIA card inserted into slot 0
 <5>[  155.760000] pcmcia: registering new device pcmcia0.0
 <6>[  155.900000] Serial: 8250/16550 driver $Revision: 1.90 $ 2 ports, IRQ sharing disabled
 <7>[  156.090000] pcmcia_resource: pcmcia_socket0: odd IO request: base 0x3f8 align 0x100
 <4>[  156.090000] pcmcia: request for exclusive IRQ could not be fulfilled.
 <4>[  156.090000] pcmcia: the driver needs updating to supported shared IRQ lines.
 <4>[  156.140000] ttyS0: detected caps 00000700 should be 00000100
 <6>[  156.140000] 0.0: ttyS4 at I/O 0xc4960400 (irq = 30) is a 16C950/954

We can now set up the GPS using this document.
