TWR-LS1021A supports 2Gb parallel NOR flash?

Question asked by bean huo on Feb 28, 2018


i am using TWR-LS1021A , and now want to increase on-board parallel nor flash to 256MB(2Gb). 

But I checked the schematic, its address bus range only supports A0~A25, means it only can support maximum 1Gb density NOR flash.  is this true??  is there a possibility to do change on the board to support 2Gb?
