So IFC_AD[0] is the MSB on the bus and it should be connected to MSB of the NOR flash, that is DQ[15]. This expalins "reversal" in connectivity on the IFC bus.</P><P></P><P>Regards</P></BODY></HTML> Wed, 18 Feb 2015 06:24:24 GMT https://community.nxp.com/t5/T-Series/Connecting-nor-flash-with-t2080-processor/m-p/380995#M79 Bulat 2015-02-18T06:24:24Z
