wince5.0+2440 由64M改为128M Booting Windows CE version 5.00 for (ARM)
最近在弄这个这个内存的扩展工作,硬件已经进行了修改,软件的具体修改工作如下:
1.fw.s
HandleFIQ是存放着FIQ服务程序入口地址的地址,内存多了64M，所以要加上64M的内存。
HandleFIQ EQU 0x33ffff1c
改成
HandleFIQ EQU 0x37ffff1c
这个文件第二个要改的地方
ldr r3, = (0x8C000000 - 0x30000000)
改成
ldr r3, = (0x88800000 - 0x30000000)

到此内核修改结束
但是该过之后WINCE不能正常启动,我的DEBUG版本下的系统启动信息如下:

然后就停止在此处不往下执行了,
1.ldr r3, = (0x8C000000 - 0x30000000)
改成
ldr r3, = (0x88800000 - 0x30000000)
---》这个不需要修改啊。
2.DCD 0x8C000000, 0x30000000, 64 ; 64 MB DRAM BANK 0,1
---》值需要修改为DCD 0x8C000000, 0x30000000, 128 ;而且后面的依次增加64M，也就是0想0想04000000，比如修改之前是
DCD 0x90800000, 0x48000000, 1 ; Memory control register
那应该改为
DCD 0x94800000, 0x48000000, 1 ; Memory control register
而不是像楼主那样修改
3.s2440.h
#define DMA_BUFFER_BASE 0xAC000000
---》这个不需要改
还有好一些，我就不列举了，一看就知道楼主的BSP包是之前非标准的BSP包，我们现在的产品也有类似的BSP包，我也做过SDRAM从64M升级到128M，我做了记录，楼主如有需要，我可以把这个记录文档发给你，就是关于怎么从64M升级到128M的。
驱动有地方冲突
主要是和USB的驱动程序所分配的地址冲突了，具体文件armint.c里的UsbdclearEir和ohcd.c
