The commands have usually no idea what sort of memeory  (if  any)  is

attached  to  the addresses you pass. [Exception is cp and - epending

on the configuration - tftp which recognize NOR flash areas  and  use

flash write code then.]

cp is the only regular command to write to NOR flash.  It  cannot  be

used for NAND, though. NAND has it's own interface, the nand command.

 

Best regards,
