Hopefully a simple question, but I can't seem to find a concise answer. Simply put, when mapping an 8 bit parallel gray scale sensor to the 20 bit parallel CSI port, what are the mapping options. I see the SDB board uses the top 8 bits (D12:D19) of the CSI port. I recall reading somewhere that the next 8 bits down (D4:D11) are also supported. I think I've also seen the low 8 bits used.
I just want to capture a byte oriented frame buffer without any overhead so I want to be sure I pick a mapping that doesn't force me to capture 16 or 32 bit words. I assume whatever mapping restrictions there are they are the same for all i.MX6?
