wince 地址迁移问题

wince 地址迁移问题 [复制链接]

小弟在做2410wince驱动
需要把一个
#define PD6710_MEM_BASE_ADDRESS     (0xA4000000)        //(0x04000000)NgCS2 0x04000000
#define PD6710_IO_BASE_ADDRESS      (0xA5000000)        //(0x05000000)//      0x05000000

迁移到nGcs5 地址区间  
请问 是直接把上面的地址提升128M*3 就行了吗 谢谢

今天上午我也碰到了一个类似的问题如下:
        pNANDFConReg = (volatile S3C2443_NAND_REG *)0xB1400000;                        // 0x4E000000
        pMatrixConReg = (volatile S3C2443_MATRIX_REG *)0xB1500000;                        // 0x4E800000
        pDMAConReg = (volatile S3C2443_DMA_REG *)0xB0E00000;                                // 0x4B000000
        pIOPortReg = (volatile S3C2443_IOPORT_REG *)0xB2100000;                        // 0x56000000

看看2410手册中内容映射部分的ngcs5的地址范围就明白了。。

我的意思是说  wince里的虚拟地址映射是啥样的

你应该看一下OEMAddressTable，看看这个表里面是否有这个片选对应的物理空间及相应的虚拟地址空间。

好的 谢谢楼上

小弟找到了
在\WINCE420\PLATFORM\SMDK2410\KERNEL\HAL\ARM\map.a 里查到

再次感谢楼上

; Module Name:
;
;    map920.h
;
; Abstract:
;
;   This module contains the OEM memory map for the S3c2410
;
;--


;
; OEMAddressTable defines the mapping from the 4GB physical address space
; to the kernel's 512MB "un-mapped" spaces.  The kernel will create two ranges
; of virtual addresses from this table. One from 0x80000000 to 0x9FFFFFFF which
; has caching & buffering enabled and one from 0xA0000000 to 0xBFFFFFFF which
; has the cache & buffering disabled.
;
; Each entry in the table consists of the Virtual Base Address to map to,
; the Physical Base Address to map from, and the number of megabytes to map.
;
; The order of the entries is arbitrary, but DRAM should be placed first for
; optimal performance. The table is zero-terminated, so the last entry MUST
; be all zeroes.
;
       
; Mapped for S3C2400X01

小弟第一次发贴,感谢上面同志们的回帖,我不太知道怎么结贴  刚才一不留神给加了120分...对不住  改不了了  管理员能否修改一下 50分就行了  谢谢  不好意思啊  汗.....
