怎么能使用最大64k的闪存?

嗨,没有任何一个有如“代码银行“我FX2(高达16K的代码/数据)和闪光(24LC64)64 kb的我如何能使用的最大闪光64K?帕斯卡

          Hi,   
Does any one have example for "Code banking" i have FX2 (up to 16k code/data) with flash (24LC64) of 64 kb how can i use the maximum the 64k of the flash?

FX2LP 128引脚版本能够与外部存储器工作,可以支持代码高达64KB…当代码大小远小于该代码时,为什么要进行代码银行业务??

          FX2LP 128 pin version is capable of working with external memory and can support code up to 64KB... why do you want to go for code banking when your code size is much smaller than that??

1。当代码越来越大时,FX2有16字节的片上代码/数据RAM,然后从KEIL ***错误L107中获得错误:地址空间溢出。2。对于64K闪存的FX2,我如何能够在16K的限制下进行编码,而不需要代码银行?三。我们有64K的小闪光灯,但我们将升级到1M闪存AM29 LV010B,为将来的代码扩展,应该是非常大的。泰纳克斯

          1. the FX2 has 16 KBytes of On-Chip Code/Data RAM when the code is getting bigger then that i getting error from keil *** ERROR L107: ADDRESS SPACE OVERFLOW.   
2. for the FX2 with 64k flash how i can code over the 16k limit without code banking?   
3. we have the small flash of 64k But we going to upgrade to 1M flash AM29LV010B for future expansion of the code that should be very large.

在你的设计中,64K闪存是如何连接到FX2的????如果你下载DVK,你可以注意到FX2连接到一个SRAM并使用它作为外部存储器,在这种操作中它可以理论上有一个64K大小的固件。KEIL工具链能够生成代码存储固件…我所困惑的是,你是不是真的在使用一个串行接口,并不时地下载代码到内部RAM,试图实现代码银行,或者你使用一个并行接口,并想对它进行编码。

          How is this 64k flash connected to FX2 in your design???   
If you download the DVK, you can notice in the schematic that FX2 is connected to a SRAM and uses it as external memory and in this kind of operation it can theoretically have a firmware of size 64k...   
Keil tool chain is capable of generating code banked firmware... what i'm confused is whether you are actually using a serial interface and downloading code to internal RAM from time to time and trying to achieve code banking or are you using a parallel interface and want to code bank it....
