Using adv7604 video decoder in dm8148 board

Other Parts Discussed in Thread: TVP7002

Hi ,

I am using a custom board with DM8148 in which the adv7604 video decoder is attached. Please tell me what are the changes I need to do in the "arch/arm/mach-omap2/ti81xx_fb.c" and "vi arch/arm/mach-omap2/board-ti8148evm.c" file for using adv7604 video decoder instead of tvp7002 video decoder.

In my custom board, the video decoder is attached to the i2c bus 0.

Thanks,

Debasish

HI Debashish,

If you have v4-l2 subdevice developed for adv7460 already, yu need to modify

ti81xxvin_main.c
ti81xx_vpss.c
board-ti8164evm.c
ti81xx.h and few other files.

Please refer the link. Some customer has integrated tvp5158 instead of tvp7002 to V4L2 capture.
