Hi,
请教专家,我们采用AM335x的GPMC总线与FPGA连接,进行数据的传输。GPMC采用异步读写模式。写操作完全正确,读操作的时候,读到的数据不对。用FPGA内部的在线逻辑分析工具抓到的波形如下:
我们期望的是当GPMC_addr = 0D的时候,读到的数据GPMC_data = 0FFF。但是结果却总是读到后面的数据0FDF。想求助专家:1、为什么会读到后面的数据去了?2、怎么解决这个现象呢?
Best regards,

Hi,
Do you have any other better ideas about this issue? Why didn't I get a more promptly and more effective suggestion? Is TI's FAE so unprofessional that it never encounters a similar simple issue that giving nothing reasonable solution?
Look forward to your favorable reply and thank you very much.
Best regards,
