Flash memory application

Hello, All!

What is the common practice for flash memory application for bootloader: NOR or NAND? And the same question - for kernel image storing and file system.

Thanks in advance.

Whichever is cheaper in your application?

The thing to watch out for is that for first boot you need some memory that can be directly addressed by your CPU, i.e. execute-in-place. Not all memories support this, e.g. CompactFlash is sector-addressed and would require very complex interface logic -- it would be cheaper to buy a small primary bootstrap (which is, in fact, often done.)
