Porting FM In Android Along With The Application

[Ranganath TM]

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

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 -

Hi Ranganath,

               You might also check this link if the FM chip is Si Labs one.

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

Hi Manju,

Can you send the path of Android FM Android application, so that I can analyze the complete flow from application layer to the kernel, And I can get better idea to implement.

Thanks,

Hi Jhon,

You have to have complete Android source code to build this.

You can get the source code for Panda board from below locations

ICS FS:
http://source.android.com/source/downloading.html

Google OMAP Kernel:
https://android.googlesource.com/kernel/omap.git
Branch: origin/android-omap-panda-3.0

This code will have the FM source code by default

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 

[halli manjunatha]

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

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

[halli manjunatha]

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

Hi Manjunath,

can you please tell the .mk to add kfmapp so that I can build it.

Thanks,

Ranganath.T.M    

[halli manjunatha]

The above mentioned link has kfmapp.c kfmapp.h and Android.mk copy all
these things in to a folder.

In the parent folder within which this kfmapp folder is present you
have to have below line to use the Android.mk of kfmapp.

include $(call first-makefiles-under,$(call my-dir))

I think this will solve your problem.

Hi Manjunath,

Thanks for your time,

I want to add the FMRXAPP to eclipse, 

I am not getting how to make it,

because the Android SDK does not contain any FM Api's,

please guide to resolve this issue.

Thanks,

Ranga

[halli manjunatha]

Hi Ranganath,

Sorry for delayed response.

Even I never used this app on Eclipse.

But you can try it by removing the dependicies of JNI layer in FM RX
JAVA files (FM/FmRxApp/src/com/ti/fmrxapp/FmRxApp.java).

Hi Manjunath,

Now I am able to build my driver framework and application on our board,

The device is getting opened and Firmware is downloaded,

can you tell me the command in terminal to open the FM Module and make it running,

For example to enable WIFI I am using svc wifi enable.

And also do you know how to run android command line application.

Thanks,

[Ranganath TM]

Hi Manjunath,

Do you Know In android how to do library registration,

I am getting an error library not yet registered,

For example I want register libfmradio.so where to make it,

please help in resolving these issue.

Thanks,

Ranga 

[Ranganath TM]

Hi Manjunath,

I am able to switch on my device,

Able to set it in to RX mode,

when try to scan the frequency I am getting the following error,

vidioc_get_ext_ctrls: Id = 8001010,ext_ctrl->ctrl_class = 980000VIDIOC_G_EXT_CTRLS:error!!

continously.

Thanks,

Ranga 

[halli manjunatha]

Ranganath,

Does your driver supports ioctl VIDIOC_S_HW_FREQ_SEEK? seems its not.

Thing is FM JNI calls this v4l2 ioctl when you do seek from the GUI.

Can you give me the link to your driver so that we can verify this.

If your driver is not supporting VIDIOC_S_HW_FREQ_SEEK ioctl then need
to tweek the FM JNI so that it will do SET_FREQ (for 200KHz gap
between 2 channels) and check the signal strength if signal strength
is good enough then come outt of seek else check next frequency.

Meanwhile you can check the set_freq by selecting
(menu->set_frequency-> enter the frequency desired in MHz).

Hi Manjunath,

When I lunch My FM RX application it is giving me the error as "vendor registration failed".

In JNI file android_fmradio.cpp  In the below function,

// if we haven't registred the library yet do it

    if (!session_p->isRegistered) {

        session_p->vendorMethods_p = (fmradio_vendor_methods_t *)

            malloc(sizeof(*session_p->vendorMethods_p));

        if (session_p->vendorMethods_p == NULL) {

            free(session_p->vendorMethods_p);

            retval = FMRADIO_IO_ERROR;

            goto early_exit;

        }

    }

I am not getting things how to do it ,

Please help me regrading this.

Thanks,

Hi Ranganath,

Which FM framework you are using?.. seems this error message is not
from TI's FM framework.... and more like ST Ericsson's FM solution

Anyway this error message indicates you dont have the Vendor specific
handlers required by the framework.(like FM framework calls JNI layer
for FM turn ON but there is no link exist between FM framework and
V4L2 Fm driver to do this).

I am looping Anupam Roy who is working in this front.

Hi,

 The error message indicates that the JNI layer is not able to find the vendor specific handler as already indicated by Manju.

The vendor driver is seeked run time in /system/lib on phone. To support the usage of different TX and RX chip, the search will first be done for a library libfmradio.(*)_rx.so (rx mode) / libfmradio.(*)_tx.so (tx mode), if neither is found it will try to load libfmradio.(*).so.

Therefore if you are using the STE FM Radio framework, the vendor library naming format should be of type..

libfmradio.(*)_rx.so
libfmradio.(*)_tx.so
libfmradio.(*).so

Hi Anupam,

yes I am using  STE vendor plugin, 

and you are right it cannot map the valid V4L2 format,

In  the file ste_fmradio_cg2900.c and in that function get_interrupt they are passing the controls.id  has V4L2_CID_CG2900_RADIO_GET_INTERRUPT,

but in the driver file radio-cg2900.c in the function vidioc_get_ext_ctrls there is no such case,

so it is going for default case,

can you help in resolving the issue,

Thanks,

The case “V4L2_CID_CG2900_RADIO_GET_INTERRUPT” is indeed missing, but if You don’t support the above events, this particular case would not work as it is!

Hi Anupam,

As you said it's right no device is adding to /dev directory except cg2900_core_test,

but what we are not getting any hint to suspect initialization problem,

Can you please suggest me how we can debug to find out whether it is initialization problem or something else,

as per as my analysis in GB the function cg2900_UART_probe is called and cg2900_hu_open is also called,

but in case of ICS cg2900_UART_probe is getting called but not cg2900_hu_open  and the chip reset and reading of chip information done 

after this only, can you please confirm on this, and can you please help to find out how the function cg2900_hu_open is called is it any way 

related to chip initialization. 

Thanks,

Hi Ranganath,

 

Possibly the CG2900 connectivity device could not initiate properly.

 

During this initialization, various MFD device nodes are also created. All these nodes should be available in /dev folder for e.g..

 

cg2900_audio

cg2900_bt_acl

cg2900_bt_audio

 

Only after this, FM Radio kernel driver is probed and registered as platform driver.

 

For e.g FM Kernel driver will be registered as platform driver and \dev\radio0 node should get added!

yes we are using git provided by STE .

2)      Do you see file clock-cg2900.c in path /kernel/drivers/staging/cg2900, can you provide me a zip of it?

PSA for CG2900 zip file

3)      Are you getting this error even after modifying the entry in init.rc?

Hi Ranganath,

This is strange.

For some background, Wlan requires a clock from cg2900 chip, for that purpose “sys_clk_out” is the clock which cg2900 adds for wlan to be used. For my knowledge can you tell me few things:

 

1)      About your environment: are you using git provided by STE, which SI version (repo tag) are you using?

2)      Do you see file clock-cg2900.c in path /kernel/drivers/staging/cg2900, can you provide me a zip of it?

3)      Are you getting this error even after modifying the entry in init.rc?

4)      For experiment, Can you first switch on BT and keep it on and then enable WLAN, do you still see this issue?

Hi Nitin,

Thanks for support,

please find the in-line comments

Hi Ranganath,

There could be multiple reasons for this:

1)      There are 2 wlan modules, one is umac and the other is open mac. It could be that some wrong binary has gone for wlan. Can you tell me how you do make for the complete system? And do you separately build kernel?

                       yes we will make complete system, please find below make command we use for build,

                   

                      source build/envsetup.sh && lunch ste_u8500-eng && make -j18 STE_USE_MOD_APE=1 FLASHKIT_ENABLE_                          MODEMINFILELIST=false COPS_ENABLE_SILENT_REBOOT_SUPPORT=false

                       

a.       To verify umac or openmac module inside the flashed image; goto /system/lib/modules/3.0.8+/kernel/net and do an “ls”. Give the name of the directory that is displayed.

                                Its a openmac, pls find the below log..

                               # cd /system/lib/modules/3.0.8+/kernel/net

                               # ls

                               compat-wireless-openmac

b.      To check the compilation flag, open file: vendor/st-ericsson/u8500/BoardConfig.mk and check flag WLAN_ENABLE_OPEN_MAC_SOLUTION, whether this is true of false.

          It is True 

2)      You may require to do some debugging by putting printks:

a.       file: clock-cg2900.c, function: cg2900_core_probe – this will confirm that clock is added by cg2900. And verify these prints during bootup.

                                Please find the log attached 

b.      Similarly, put prints inside file: kernel/arch/arm/mach-ux500/board-mop500-wlan.c function: cw1200_clk_ctrl and inside condition “if(enable)” – this will verify some wrong functionality of calling twice might not have happened.

                     Please find the log attached

Please do these and let me know.

 

Regards

Nitin

Hi Ranganath,

Hi Nitin,

Thanks so much for your support,

 Ajit,

Hope your doing well,

I am assuming that you are aware of current issue,

I am facing the below issue when I am trying to enable WIFI,

ADDRCONF(NETDEV_UP): wlan0: link is not ready,

I am suspecting the issue would be in WPA_Supplicant,

can you please help me in resolving the issue,
