从上面来看是否意味着对Parallel Flash Memory的擦除失败?

 

 

 

另外, Robin的邮件建议“不用AMS3接NOR FLASH片选, 可以接AMS0-2任意一根片选.”

 

请问我需要如何操作呢?是否在评估板上的SW3开关上进行怎么操作呢?

i already told you -- you cannot use the 4th async bank with the last release.  so dont.

 

as for switch settings, read the documentation:

thanks, 您指的是ASYNC MEMORY BANK 3 (1M BYTES)这个无法使用, 也就是最大只能用到3M Bytes的空间, 是这样理解吗?
