Hi Fabio,
I get a magenta line down the left side of the screen unless I replace
the 5 with a 6.
ie.
+ for (count = 0; count < 6; count++)
+ hdmi_writeb(hdmi, val, HDMI_FC_INVIDCONF);
This is with a imx6q processor. With the 6, the picture looks great!
Troy
It also works if I change the 5 to a 4! A 3 fails though.
To summarize:
0 works
1 fails
2 works
3 fails
4 works
5 fails
6 works
Very strange.
Troy
