Just build you FM V4L2 driver as part of the your kernel and boot the board.
Once after booting the board you will have /dev/radio0 entry for your FM radio. Seems you need to change the /dev/radio0 permissions to "666" you can use the kfmapp (V4L2 compliant FM test application) at below location to validate your FM driver. http://git.omapzoom.org/?p=platform/hardware/ti/wpan.git;a=tree;f=tools/kfmapp;h=710184f873149f05c0550253419872ad8a0cce1d;hb=d03a9f4296d7b8523ad857dcf225287ab7d51a90 So if your FM driver is fully compliant with the V4L2 specifications then, copy the complete FM GUI solution to package/apps/ of your Android source code and build it, this create following 1) system/lib/libfmradio.so 2) system/etc/permissions/com.ti.fm.fmradioif.xml 3) system/app/FmRxApp.apk 4) system/app/FmTxApp.apk 5) system/app/FmService.apk Now copy these binaries to your filesystem and boot the board. Now you can see 2 icons on your android application pane one for FM RX and one for FM TX, just launch the FM RX icon which eventually opens the /dev/radio0 Regards Manju On Tue, Mar 27, 2012 at 10:37 AM, Ranganath TM <[email protected]> wrote: > Hi Manjunath, > > Thanks for your time, > > I am working on Snowball AP9500 processor, > > I am little bit confused about the folder structure, > > can you please guide me in adding the FM Module it. > > Thanks, > > Ranganath.T.M > > > On Tue, Mar 27, 2012 at 8:46 PM, halli manjunatha <[email protected]> > wrote: >> >> Hi Ranganath, >> >> If your driver is V4L2 compliant then you can just use the complete >> solution straight forward with minimal changes to JNI part which is at >> service/src/jni/JFmRxNative.cpp for FM RX and >> service/src/jni/JFmTxNative.cpp for FM TX >> >> Regards >> Manju >> >> On Tue, Mar 27, 2012 at 5:22 AM, Ranganath TM <[email protected]> >> wrote: >> > Hi Manjunatha, >> > >> > Thanks for your support, >> > >> > My FM driver is V4L2 complaint driver, >> > >> > can you please explain me where to modify, >> > >> > how can I proceed further. >> > >> > Thanks, >> > >> > Ranganath >> > >> > On Wed, Mar 21, 2012 at 9:12 PM, halli manjunatha <[email protected]> >> > wrote: >> >> >> >> Hi Ranganath, >> >> >> >> I dont know about the AW chip but you can use the above mentioned >> >> framework for your chip with little modifications as below >> >> >> >> Is your FM driver is a V4L2 compliant driver? if yes then you can use >> >> the >> >> complete FM package as is without much modifications >> >> >> >> If your FM driver is not a V4L2 then you need to modify the JNI part of >> >> the FM package means you just needs to rewrite the >> >> FM/service/src/jni/JFmRxNative.cpp file for your driver >> >> >> >> Regards >> >> Manju >> >> >> >> On Wed, Mar 21, 2012 at 9:13 AM, Saravanaperumal Annamalai >> >> <[email protected]> wrote: >> >>> >> >>> Hi Ranganath, >> >>> You might also check this link if the FM chip is Si >> >>> Labs >> >>> one. >> >>> >> >>> http://mmbtools.crc.ca/content/view/53/33/ >> >>> >> >>> >> >>> Regards >> >>> Saravana >> >>> >> >>> >> >>> >> >>> On Wed, Mar 21, 2012 at 12:37 AM, halli manjunatha >> >>> <[email protected]> >> >>> wrote: >> >>>> >> >>>> Hi Ranga, >> >>>> >> >>>> As for I know you wont find a standard API set for FM radio in >> >>>> Android, cos Google doesn't supports FM by default and so all the >> >>>> vendors are using there own home brew FM framework. >> >>>> >> >>>> One such thing is Texas Instruments FM radio solution below links >> >>>> give >> >>>> you the details >> >>>> >> >>>> 1) driver - >> >>>> >> >>>> http://git.omapzoom.org/?p=kernel/omap.git;a=tree;f=drivers/media/radio/wl128x;h=231954bbc6a9e234cc2bfca53eb02f28b7a7d407;hb=460374248586421260dbffca91454907ff8c5ada >> >>>> >> >>>> 2) FM framework - >> >>>> >> >>>> >> >>>> http://git.omapzoom.org/?p=platform/hardware/ti/wpan.git;a=tree;f=tools/FM;h=3f950c8b2e0cae5f540caabb58a7f114cc78bb8f;hb=bebfa00ede52e48e205c9c8de4012b52184a9214 >> >>>> >> >>>> Regards >> >>>> Manju >> >>>> Regards >> >>>> Manju >> >>>> >> >>>> On Tue, Mar 20, 2012 at 2:05 AM, Ranganath TM >> >>>> <[email protected]> wrote: >> >>>> > Hi All, >> >>>> > >> >>>> > I am trying to port an FM in android GB, along with my application >> >>>> > for >> >>>> > AWNH580(Azurewave FM hardware module), but to write an application >> >>>> > I don't have any specific API. >> >>>> > >> >>>> > please help to write an application and to port the FM module. >> >>>> > >> >>>> > Thanks, >> >>>> > Ranga >> >>>> > >> >>>> > -- >> >>>> > unsubscribe: [email protected] >> >>>> > website: http://groups.google.com/group/android-porting >> >>>> >> >>>> >> >>>> >> >>>> -- >> >>>> Regards >> >>>> Halli >> >>>> >> >>>> -- >> >>>> unsubscribe: [email protected] >> >>>> website: http://groups.google.com/group/android-porting >> >>> >> >>> >> >>> >> >>> >> >>> -- >> >>> Regards >> >>> Saravana >> >> >> >> >> >> >> >> >> >> -- >> >> Regards >> >> Halli >> > >> > >> > >> > >> > -- >> > Thanks And Regards >> > Ranganath T.M >> > >> >> >> >> -- >> Regards >> Halli > > > > > -- > Thanks And Regards > Ranganath T.M > -- Regards Halli -- unsubscribe: [email protected] website: http://groups.google.com/group/android-porting
