Greetings,

 

If one wanted to add flash memory to an i.MX6S with a SPI nor flash, what is the limiting factor for the maximum addressable memory?  I see references in the manual that state a 16k memory size size for SPI boot, and I also see a setting for 16-bit or 24-bit (but I'm not sure this refers to the address bits).
