compiling Linux-davinci image

benon kagezi

I am using the DM368EVM.., I am trying to get the mt9p031 driver compiled so that I can use Gstreamer.

I am trying to just get the camera running and storing the video on the target, or stream it onto the LCD touch screan that comes with the DM368EVM module.

I follow the instructions at: http://processors.wiki.ti.com/index.php/UG:_DaVinci_PSP_Installation_on_DM36x_EVM#Building_and_using_the_MT9P031_CMOS_image_sensor_driver

I am using the latest src from: git clone git://arago-project.org/git/projects/linux-davinci.git linux-davinci

At the tail end after typing "make" I get the error below.

LD drivers/media/video/davinci/built-in.o
CC [M] drivers/media/video/davinci/vpss.o
drivers/media/video/davinci/vpss.c:28:27: error: mach/hardware.h: No such file or directory
make[4]: *** [drivers/media/video/davinci/vpss.o] Error 1
make[3]: *** [drivers/media/video/davinci] Error 2
make[2]: *** [drivers/media/video] Error 2
make[1]: *** [drivers/media] Error 2
make: *** [drivers] Error 2

How do I solve this error? Or is there another way to stream video from the camera and store it.

Thanx.

Hi,

I am using the latest version (1st July 2012). I used the git command.

This doesnt answer my question "which branch are you using" ?

which branch did you checkout (git checkout) from the arago, for ex the branches present

in arago are davinci-next, master dvsdk... so which one of these did you checkout and you are trying to build ?

Thx,

Hi,

I checked out using:

git clone git://arago-project.org/git/projects/linux-davinci.git linux-davinci

The above command doesn't checkout a branch it clones a tree.

to checkout a branch refer this link http://linux.die.net/man/1/git-checkout

Hi Prabhkar

I dont know which branch the command git clone git://arago-project.org/git/projects/linux-davinci.git linux-davinci gets. I see there are three branches as you mentioned, davinci-next, master and DEVDAVINCIPSP...

Hi,

The command which you issued clones entire tree, so now the question is on which branch you want to work on ?

Thx,

Hi Prabhakar

I want to compile to compile the mt9p031 driver. I am assuming the driver will be in the master branch. So I am going to try use the master branch.

Thanx.

Hi Prabhakar

I checked out master, and does not have the mt9p031 driver, so I checked out the dvsdk branch, and I get the error:

CC [M] drivers/media/video/davinci/vpss.o
drivers/media/video/davinci/vpss.c:28:27: error: mach/hardware.h: No such file or directory
make[4]: *** [drivers/media/video/davinci/vpss.o] Error 1
make[3]: *** [drivers/media/video/davinci] Error 2
make[2]: *** [drivers/media/video] Error 2
make[1]: *** [drivers/media] Error 2
make: *** [drivers] Error 2

The steps I follow are:

1. make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- menuconfig
2. make

What am I not doing right?

Hi,

I checked out master, and does not have the mt9p031 driver, so I checked out the dvsdk branch, and I get the error:

What command did you issue to checkout ?

Please follow the below steps to build and checkout:

1: git checkout -b <local branch name> origin/dvsdk

2: make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- clean distclean

3: make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- davinci_dm365_defconfig

4: make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- uImage -j 48

I checked out this branch and built it successfully

Thx,

Thanx Prabhkar

One more question: The compiled object is a .o format. How do I compile the mt09p031.c to mt09p031.ko instead of mt09p031.o

“CONFIG_SOC_CAMERA_MT9P031=y” is included in linux-davinci/arch/arm/configs/davinci_dm365_deconfig

Thanx.

The mt9p031 driver is built along with the kernel, you don’t need to build a ko file.

For enabling mt9p031 you need to set vpfe_capture.interface=1 in bootargs.
