Hi,
I developed a proprietary board based upon DM365 UdWorks RDK. Video front end consists of a DM365 coupled with a single TVP5158 video decoder connected as in UdWork schematic except of slave video decoder.
I used mcvip_test.out application to display the captured video using option 5 (4 channel in CIF format) but the image lacked of red components, so I forced "blue" screen output from TVP5158 setting registers as follows:
reg 0xA9 = 0x08
reg 0x90 = 0x80 (Y component)
reg 0x91 = 0x40 (Cb component)
reg 0x92 = 0x20 (Cr component)
Checking TVP5158 output with oscilloscope I don't see any output of Cr component and also, saving frames on file there's no Cr component.
This is YUVIN_0000_384x288.BIN first line: 40 80 40 80 40 80 40 80 40 80 40 80 40 80 40 80 ...
Any suggestions?
Thanks in advance.
Stefano
