Flash 地址空间

[梦]

所有空间 0xFFC00000~0xFFFFFFFF 总容量4M
redboot空间 0xFFFE0000~0xFFFFFFFF 大小128K
以后写内核可以从 0x00000000开始写。

要据刷RDC在刷flash输出的内容

( 0)Address = 0xFFFE0000, Length = 7970
( 1)Address = 0xFFFE2000, Length = 7790
( 2)Address = 0xFFFE4000, Length = 7680
( 3)Address = 0xFFFE6000, Length = 7934
( 4)Address = 0xFFFE8000, Length = 8036
( 5)Address = 0xFFFEA000, Length = 7848
( 6)Address = 0xFFFEC000, Length = 7974
( 7)Address = 0xFFFEE000, Length = 7950
( 8)Address = 0xFFFF0000, Length = 7990
( 9)Address = 0xFFFF2000, Length = 8082
( 10)Address = 0xFFFF4000, Length = 8192
( 11)Address = 0xFFFF6000, Length = 8168
( 12)Address = 0xFFFF8000, Length = 8192
( 13)Address = 0xFFFFA000, Length = 8192
( 14)Address = 0xFFFFC000, Length = 8192
( 15)Address = 0xFFFFE000, Length = 8180
可以知道0xFFFE0000~0xFFFFFFFF为redboot区域。
