15 years agoHi and thanks for your reply, I attached a screenshot to this post.
My Configuration is:
IOWR(ALT_VIP_VFR_0_BASE, 3, 0); // Frame Select
IOWR(ALT_VIP_VFR_0_BASE, 4, DDR_SDRAM_BASE); // Frame 0 Base Address
IOWR(ALT_VIP_VFR_0_BASE, 5, 384000); // Frame 0 Words
IOWR(ALT_VIP_VFR_0_BASE, 6, 384000); // Frame 0 Single Cycle Color Patterns
IOWR(ALT_VIP_VFR_0_BASE, 7, 0); // Frame 0 Reserved Bit
IOWR(ALT_VIP_VFR_0_BASE, 8, 800); // Frame 0 Width
IOWR(ALT_VIP_VFR_0_BASE, 9, 480); // Frame 0 Height
IOWR(ALT_VIP_VFR_0_BASE, 10, 3); // Frame 0 Interlaced
IOWR(ALT_VIP_VFR_0_BASE, 0, 1); // start Frame Reader @Hans: I think there is one value wrong in your configuration: IOWR(ALT_VIP_ITC_0_BASE, 11 ,261); // HORIZONTAL BLANK in my calculation Horizontal Blank must be frontporch+syncpulse+backporch = 40+1+216 = 257. Can you tell me, why you used 216? Thanks.
