需要连接128MB 的NOR FLASH , OMAPL138 的EMIFA 地址总线最大可以达到多少？ 能否配置出128MB EMA_A[26:0]
EMIFA的地址线总共23根，2根EMA_BA[1,0]线，所以每个CS空间的寻址空间是2^25=32M，总共有4个asyn CS空间，EMIF的总寻址空间为128M. 接128MB的Nor flash可以参考下面Wiki网站上的接法。http://processors.wiki.ti.com/index.php/Connecting_NOR_Flash_to_OMAP-L138#Hardware_Connection_for_64Mx16_device
