How to test TV-IN ( ADV7180) for IMX53 ARD board

Swamy — Wed, 18 Apr 2012 13:21:41 GMT

Hi All,

I am using IMX53 ARD board with android 2.3.4.

I enabled the driver under Device Drivers > Multimedia device > Video Capture Adapters > MXC Camera/V4L2 PRP Features, and now my .config file is updated with "CONFIG_MXC_TVIN_ADV7180=y"...

Please let me know how shall I verify the video in? I have connected the camera to J42 connector of the ARD board.

Regards,

Swamy

I have tested it only using unit_test.

But I think you can refer the unit_test source code, and create a simple app in order to test it.

Otherwise, if you can only test, it would be better take a pre-built linux image and test it. After that you can start your app.

OK Thanks, I will take a look into the unit test program.

But normally when we enable the adv7180 tv-in driver from menu config and port it to the board, how to launch the TV-IN mode?

Please suggest

you can configure kernel to build in the module, so you will not need insmod or modprobe

but I have no idea if there is any other program to be used instead of insmod and modprobe.

I have insmod working. Please tell me how to enable the driver and check for the tv-in

configure the module as 'build-in', then you will not need to insmod.

then run the unit-test program : mxc_v4l2_tvin.

Hi Charles,

Thanks for the response.

Currently I have enabled the driver using the menuconfig, Device Drivers > Multimedia device > Video Capture Adapters > MXC Camera/V4L2 PRP Features, and now my .config file is updated with "CONFIG_MXC_TVIN_ADV7180=y"

I am using the Android 2.3.4 on ARD. I do not have this unit test package. Please tell me how to get this and test?

Regards,

Swmay

Hi Angolini,

Is it possible to share me the unit_test source code or any place where I can get it?

Regards

Swamy

Hi Swamy

Maybe, would be better you start to work with this device using a linux only enviroment.

You can download LTIB from link I sent you, install and load it. Once you have seen this TVin working you would have better knowledge to create your onw source code to test it on android enviroment.

For build in a module, when you configure kernel to use it, instead of pressing space once, press it twice. Instead of "M" (that means build as module) you will see "*", that means built in.

Thanks Angolini I will check it.

Hi Angolini,

I downloaded 11.05 BSP and I checked /opt/freescale/pkgs....I could not locate the unit test source code there.

daiane_angolini — Thu, 19 Apr 2012 15:04:22 GMT

sorry, my mistake

the package name for unit_test is not unit_test =P

It´s imx-test-X.X.tar.gz

X.X is the release number

Re: How to test TV-IN ( ADV7180) for IMX53 ARD board

charleschang — Fri, 20 Apr 2012 03:21:04 GMT

right, it's in the test package,

and modify the fb dev path, the test program can be run on android.

Hi Charles,

Could you please tell me how to use this test package in android environment?

We are trying to cross compile the test package and we are getting too many errors on include paths not able to find headers...

sudo make PLATFORM=arm LINUXPATH=/home/android/myandroid/kernel_imx/include KBUILD_OUTPUT=/home/android/Desktop CROSS_COMPILE=/home/android/myandroid/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-

Please tell us where exactly I am doing wrong?

Also please tell me where exactly we need to modify the fb dev path?

Swamy

Hi Charles,

I copied directly the test file and ran on the android, it gives me permission denied error, the persmission to the file also set to read+write+executable. Still it throws that error.

Also,

We were able to cross compile the imx-test-11.05.01.tar.gz test package and generate the mxc_v4l2_tvin.out binary which is an ARM executable,but when we try to run it on the ARD board we get Permission Denied error.

#./mxc_v4l2_tvin.out -ow 1024 -oh 768 -ol 10 -ot 20 -f YU12

./mxc_v4l2_tvin.out: permission denied

Can you please tell us whether the problem is with the binary or how to give permissions so that we can run it on the ARD board.

The errors occurred while Cross compiling...

Hi All,

We are able to build the file now...but we are getting following error when we run the binary file...can you please suggest.

daiane_angolini — Tue, 24 Apr 2012 16:30:40 GMT

unrecognized std should be that you´re trying to decode a unrecognized standard.

Do you have any other capture device?

Hi Daiane,

We tried connecting(to J42) different digital camera with video mode ON and also connected DVD player, we are getting following error for both.

bash-3.2# ./mxc_v4l2_tvin.out -ow 1024 -oh 768 -ol 10 -ot 20 -f YU12
TV decoder chip is adv7180_decodmxc_v4l_close: release resource

In driver we have enabled (*) Device Drivers > Multimedia device > Video Capture Adapters > MXC Camera/V4L2 PRP Features, and now my .config file is updated with "CONFIG_MXC_TVIN_ADV7180=y"

Is there anything we need to further enable? and any arguments we are missing in the command

# ./mxc_v4l2_tvin.out -ow 1024 -oh 768 -ol 10 -ot 20 -f YU12

copy mxc_v4l2_tvin.c to android framework folder,

write an Androidk.mk for it:

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)

include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := eng
LOCAL_MODULE := mxc_v4l2_tvin
LOCAL_SRC_FILES := mxc_v4l2_tvin.c
LOCAL_SHARED_LIBRIES := libc
include $(BUILD_EXECUTABLE)

then run mm command, it will be build and place on the out folder.

I don´t know.

Maybe it´s time to start the debug.

Please, share dmesg.
