Hi!
1.- Both Flash and RAM. I already know that it's risky, but we cannot afford a bigger uC for this project. So I had to reduce the provided APP (the TV one), maintaining the API without changes. In this way, if the API is ok, it wouldn't mind whether the app is developed from the beginning by me or an addapted one from ADI. In any way, the ADV7611 shouldn't enter a state where I cannot go out without reseting the device.
2.- The ADV7611 is directly connected to an FPGA.
3.- The problem is that we are using this automatic CSC. For some reason, the ADV7611 stops decoding the AVI infoframes and the CSC is not able to determine which color space is present at the input, so it configures de converter wrongly. If I do not use this automatic CSC, I put it in manual mode and I decode the received AVI-IF by software, the problem is the same because the ADV7611 has stopped receiving the new AVI-IF.
