We connected a analog camera to an external video-decoder (adv7180) which is connected to the viu using the 8bit itu656-interface (Vybrid VF512R3CMK4).
When we start the video-decoder it sends out the serial protocol, and we can see correctly the protocol (SAV/EAV starting with FF 00 00 XX, where XX has different state for field/vsync/hsync, ...)
The VIU detects field-irqs, but we don't get any vsync-irq.
Although we don't get any error-irqs, so it seams that the received protocol is correct (see ecc-errors in scr-register of viu), but the internal decoder from the viu-module doesn't generate a vsync-irq.
Has anybody use the viu using the 8bit itu656-mode ??
Here's the pining
PTC2 -> VIU_DATA2
PTC3 -> VIU_DATA3
PTC4 -> VIU_DATA4
PTC5 -> VIU_DATA5
PTC6 -> VIU_DATA6
PTC7 -> VIU_DATA7
PTC8 -> VIU_DATA8
PTC9 -> VIU_DATA9
PTB16 -> VIU_DATA10
PTA7 -> VIU_PIX_CLK
Another question is : How does the viu differ between 8bit and 10bit itu656-mode ?
