4.1 System platform

Hardware:

 Target board ( SAMA5D4-XULT)

 CAM8200-U Module

 SD card

 5V power adapter

Software:

 Boot image( target board\linux\image\）

 luvc_test(disk-CAM8200-U\linux\)

4.2 Preparation

1. According to the target board using a corresponding image to start the development board.

2. If the customer had modified the kernel source, the user can added the new configuration to the kernel, refer the following steps:

Enter to the following kernel: cd linux-at91 make distclean make sama5d4_defconfig make menuconfig

As the following kernel configs:

Device Drivers --->

Multimedia devices --->

[*] Video capture adapters --->

[*] V4L USB devices --->

<*> USB Video Class (UVC)

[*] UVC input events device support

Input the following commands to compile the kernel: make make uImage

You can find the file “uImage” on the directory of arch/arm/boot/, replace the uImage on the SD card and run the board.

4.3 Testing

1) Copy the file luvc_test(disk\linux\) to the SD card

2) Insert the SD card to the target board

3) Turn on the board and input the following commands:

Photographed testing:

4.3-inch LCD:

./luvc_test -c -f yuyv -s 320x240 -c --skip 10 /dev/video0

7-inch LCD:

./luvc_test -c -f yuyv -s 640x480 -c --skip 10 /dev/video0

The photo capture.jpg will be generated on the directory /tmp/.

The command "-skip 10" means skip 10 frames which can catch the image clearly.
