I have a ADV7626-based system that is working just fine. My customer asked if I could change the Free Run color from Blue to Grey.
Referencing the HW manual, section 126.96.36.199, I am changing the cp_def_col_auto, CP Map, Address 0xBF to disable insertion of default color, cp_def_col_man_val, CP Map, Address 0xBF to output default colors as given in CP_DEF_COL_CHA, CP_DEF_COL_CHB and CP_DEF_COL_CHC, then setting the def_col_cha, def_col_chb and def_col_chc to specific amounts of Green, Red, and Blue (0x80, 0x80, 0x80) respectively.
In summary: If I set register 0xBF to 0x12 I always get a nice Blue (default free run color). If I set register to 0xBF to 0x14, I get a dull green color no matter the def_col_xxx settings.
Any idea where I am going wrong with these settings?
