Atmel 9261 实现GPIO驱动的问题
lyqgzce
芯片是AT9261，Wince6.0系统。
我首先在G:\WINCE600\PLATFORM\AT91SAM9261EK_BIN\SRC\DRIVERS\下建立了一个文件夹IOLyq然后在此文件夹下建立了以下几个文件
IOLyq.cpp , IOLyq.def , IOLyq.reg , sources.cmn, makefile
文件内容分别为：
1.IOLyq.cpp
#include <windows.h>
#include <types.h>
#include <ceddk.h>
#include <memory.h>
#include <nkintr.h>

#include <Winuser.h>
#include "AT91SAM9261_oal_intr.h" //
#include "atmel_spi_ioctl.h"
#include "AT91SAM9261EK_ioctl.h" //
#include "at91sam9261_gpio.h"

然后，我更改了以下文件：
1）. 在G:\WINCE600\PLATFORM\AT91SAM9261EK_BIN\CATALOG下打开AT91SAM9261EK_BIN.pbcxml，然后添加GPIO驱动的选项，首先找到<BSP>…</BSP>并在里面添加下面一行：
<BspItemId>Item:Cirrus Logic:bsp_atmel9261_gpio_at9261_at9261</BspItemId>
然后在< CatalogFile >…</CatalogFile>中添加下面的驱动描述：
<Item Id="Item:Cirrus Logic:bsp_atmel9261_gpio_at9261_at9261">
<Title>GPIO</Title>
<Description>GPIO Driver</Description>
<Type>BspSpecific</Type>
<Variable>BSP_ATMEL9261_GPIO</Variable>
<Location>Device Drivers</Location>
<SourceCode>
<Title>$(_WINCEROOT)\PLATFORM\AT91SAM9261EK_BIN\SRC\DRIVERS\IOLyq</Title>
<Path>$(_WINCEROOT)\PLATFORM\AT91SAM9261EK_BIN\SRC\DRIVERS\IOLyq</Path>
</SourceCode>
</Item>
上面实际上添加了GPIO驱动，环境变量为BSP_ATMEL9261_GPIO，源代码位于路径”\SRC\DRIVERS\IOLyq”下面。
2）添加驱动模块到NK中
打开”files\”目录下的platform.bib文件，添加如下内容：
IF BSP_ATMEIL9261_GPIO
IOLyq.dll $(_FLATRELEASEDIR)\IOLyq.dll NK SHK
ENDIF
最后，我定制了一个OS，在Third Party中加入了GPIO那一项，（如下图，感觉此项有些不对）
但是，下载后测试GPIO控制失败，我认为是在加入驱动时出错了，另外，我点生成->open release directory in build Window 后切换至G:\WINCE600\PLATFORM\AT91SAM9261EK_BIN\SRC\DRIVERS 目录 然后 输入build 回车，结果在IOLyq目录下生成了build.log文件内容如下：

我是初学做wince驱动的，感觉这方面的资料很少，特别是CE6.0版本的，麻烦帮我看看大概是哪个地方出问题了，或者，给我些指导应该看些什么资料，谢谢。
