我们使用的是dm8168 evm 的程序代码。

我们用附件saLoopBackVip1.c 测试

附件程序有下面的定义:

#define CAPTURE_DEVICE "/dev/video5"

//#define CAPTURE_DEVICE "/dev/video0"

=============================================

关闭//#define CAPTURE_DEVICE "/dev/video5"

打开#define CAPTURE_DEVICE "/dev/video0"

测试vip0

图像正常还回。

我们的vip0 是adv7441输入的，只是把tvp7002的i2c地址改成adv7441的地址，然后在tvp7002.c的文件里修改了一些寄存器的配置。

==========================================

打开#define CAPTURE_DEVICE "/dev/video5"

关闭//#define CAPTURE_DEVICE "/dev/video0"

测试vip1 没有图像还回输出，

报告错误：
Port a overflowed

================================================

3.测试vip1是我们做了如下的修改：

在board-ti8168.c

static struct omap_board_mux board_mux[] __initdata = {

/* PIN mux for non-muxed NOR */
TI816X_MUX(TIM7_OUT, OMAP_MUX_MODE1), /* gpmc_a12 */
