GPMC可以用来外接SRAM吗?



我现在因为需要,外接了一个SRAM芯片,注意,真的是一个64K-Word Static RAM(16bit),我的问题是:

(1)这个芯片可以接到GPMC上面吗??

(2)写应用程序时,假如我要操作这个SRAM的某一个地址,请问我改怎么处理?有没有什么相关的程序或者文档能让我借鉴下。

  • 1. 参考TRM手册,应该OK。

    The general-purpose memory controller (GPMC) is an unified memory controller dedicated to interfacing
    external memory devices:
    • Asynchronous SRAM-like memories and application-specific integrated circuit (ASIC) devices
    • Asynchronous, synchronous, and page mode (only available in non-multiplexed mode) burst NOR flash
    devices
    • NAND Flash
    • Pseudo-SRAM devices

    2. 

    这个和GPMC的地址池分布设计相关,建议你参考一下这个:http://www.deyisupport.com/files/m/sitara_arm/11906.aspx
