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?
Thanks,
Dave

Hi David
only supported formats are given in
Table 66. Camera Input Signal Cross Reference, Format, and Bits Per Cycle
From sect.37.4.3.2.1 Parallel Interface IMX6DQRM :
"..according to configuration of DATA_WIDTH. If DATA_WIDTH is configured to N,
then 20-N LSB bits are ignored."
