TVP5150 Patch Update
While testing the TVP5150 boards this weekend, I found that I sometimes got video which seemed to be shifting colors. It didn’t seem to be hardware related, so I started investigating the tvp5150 register settings. I’m using the defaults for everything, but I did seem to isolate it down to the color subcarrier PLL. By setting the “Color subcarrier PLL frozen” bit, the problem seemed to go away. So, I’m attaching v2 of the patch for the RR SDK. If you’re interested in the particular change, it’s the tvp5150_init_reg_seq structure in tvp5150_davinci.c file. Here is the new version:
static const struct tvp5150_reg tvp5150_init_reg_seq[] = {
{TOK_WRITE, REG_OPERATION_MODE, 0×01},
{TOK_WRITE, REG_OPERATION_MODE, 0×04},
};
And here is the new patch…
tvp5150_v2.patch
