i want to display 720*480 video through composite output and to send YCC8 or BT.656 to daughter board on DM365.
From the following article, it seemed possible. but i couldn't find any document how to do it.
Simply, i turned on some registers relating to digital output and checked PINMUX1.
NTSC TV out is working, but i can't get any signal from digital output pins; VCLK, VSYNC, HSYNC, and YOUT0.
Please let me know where i got wrong. Any suggestion will be very helpful.
In the application, a DMAI Display instance is created with VideoStd_D1_NTSC and Display_Output_COMPOSITE.
In davinci_enc_set_ntsc(), turned on some registers: CLKCTL.CLKDIG, VIOCTL.VCLKE, and LCDOUT.OEE.
The following is VENC register setting.
