dm6446 and BT656

Other Parts Discussed in Thread: TVP5150AM1, TVP5150

Hello,


I am working with DM6446, it is connected to BT656 video source (tvp5150am1). But it seems that do not interrupt the system, and with DQBUF ioctl froze. I am testing with Texas Instruments PSP 04.02 (http://downloads.ti.com/dsps/dsps_public_sw/psp/LinuxPSP/OMAP_04_02/04_02_00_07/index_FDS.html) saUserPtrLoopback code.

I verify that tvp5150am1 registers are correct for BT656 (default values, and 0x03 (TVP5150_OP_MODE_CTL ) to 0x09 value), and Yout signals working,  And DM6446 configuration is like tvp514x system. Any ones have DM6446 registers configuration for BT656 (for compare with mine)? Any idea why DM6446 does not interrupt?


Thank you in advance.

Best regards,
