RE: FLASH_BLOCK_SIZE isnt exact.


I do not know about the MIPS atlas board, but I guess two flash memories are accessed by 32 it unit. 
That is, one for D0~D15 and the other for D16~D31. So the block size should be 256k(0x40000) instead of 128K.

Subject: [ECOS] FLASH_BLOCK_SIZE isnt exact.


For example, MIPS Atlas board use strata flash memory. As you know strata 
flash has 128kbyte block size that is 0x20000byte.

But, there (in ecos src) defined as 'FLASH_BLOCK_SIZE = 0x40000'. And this 
define is used all over the platform that use strata flash.

I cannt understand this DEFINE.

So, the question is...

1. Why does ecos define FLASH_BLOCK_SIZE = 0x40000?
2. Can I modify this define 0x20000? Is there no ploblem(eg. block_number)?

Thank you.

P.S - My platform has two E28F640.
