DM6467+TVP7002中采集1080P@50、1080P@60

Other Parts Discussed in Thread: TVP7002

各位好!我的环境是DM6467+TVP7002,TVP7002作为采集芯片,采集的数据送到DM6467的VPIF口,然后编码显示。我们已经在同一块板卡上做了采集480P/576P/720P@50/720P@60/1080I@50/1080I@60等分辨率,出来的效果很好。但是采集1080P@50和1080P@60的时候,VP口总是报错,采集不到数据,不知道为什么?我的寄存器配置是按照TI文档的推荐值进行的。如下:

1080P@60分辨率:

TVP7002配置:REG01:0x89

                            REG02:   0x80

                            REG03:   0xE0

                            REG04:   0xA0

                           REG15:   0x47

                          REG40:    0x07

                         REG41:     0x01

                           REG42:   0x8B

                           REG43:   0x08

                          REG44:0x04

                           REG45:0x04

                         REG46:0x2D

                              REG47:0x2D

                         REG48: 0x00

                        REG49:0x00

 

VPIF口的配置:

{"1080P-60", 1920, 1080, 60, 1, 0, 272, 1920, 1, 42, 1122, 0, 0, 0, 1125, 0, 0, 1},

这样配置出来后VP口一直得不到数据。请求大牛指点迷津,非常感谢!!
