- Subject: [ECOS] How to interpret hal_platform_extra.h?
Hi all,
I am working on a ixdp425 board which has 4 chips of 16M SDRAM, while
the standdard release has 4chips of 64M. It seems that I have to modify
the MMU table in hal_platform_extra.h to make it adapt to my board. But I
can't understand the following code:
======================
//256MB SDRAM
.set __base,0x000
.rept 0x100 - 0x000
FL_SECTION_ENTRY __base,0,3,0,0,1,0
.set __base,__base+1
.endr
//...some other similar sections
=======================
Could anyone please give me some advice on this? Thank you.
