2440+sm502的问题? [复制链接]

好不容易可以读到SM502芯片的DEVICE ID了,加载502驱动的时候又遇到了头疼的问题!请各位用过或懂的大侠帮忙一下,先谢过了!
问题是这样的:
首先把跟s3c2440disp显示驱动有关的都去掉,接着再加SM502驱动,步骤如下:
1、把WinCEVGX驱动复制到BSP里面
2、在platform.reg文件的最后添加
IF BSP_DISPLAY_SMIVGX
[HKEY_LOCAL_MACHINE\System\GDI\Drivers]
      "Display"="ddi_vgx.dll"
[HKEY_LOCAL_MACHINE\Drivers\Display\SMIVGX]
  "CxPanel"        =    dword:320
  "CyPanel"        =    dword:280
  "CxScreen"    =    dword:320
  "CyScreen"    =    dword:280
  "CursorZoom"    =    dword:1    ;;{0, 1}
  "Bpp"             =    dword:10    ;{8, 10, 20}
  "RefreshRate"    =    dword:3c
  "DisplayType" =  dword:3        ;;{1 = panel, 2 = CRT, 3 = panel + CRT}
;ACCELENT 2440-cgs1
  "FB_BASE"        = dword:08000000
  "FG_BASE"        = dword:0BE00000

; For DMA API on STELLCOM Peacock, should be same as in config.bib file.
;  VGXDMA    84040000  000E0000  RESERVED    ; in config.bib
;;  "SDRAM_BASE"      = dword:84000000
;;  "VGXDMABUF_ADDR"  = dword:84040000
;;  "VGXDMABUF_SIZE"  = dword:E0000
ENDIF

3、在platform.bib文件里加入以下内容
IF BSP_DISPLAY_SMIVGX
       ddi_vgx.dll          $(_FLATRELEASEDIR)\ddi_vgx.dll              NK  SH
ENDIF BSP_DISPLAY_SMIVGX

4、驱动的smi.cpp文件，最开始加入
#define HOST_ENABLE

5、build，再下载到板子上。

运行时出现错误了,调试信息如下:

感觉是gwes没加载起来,不知道是什么问题?
大家帮忙分析一下!

像见

这个和硬件紧密相关，但是做过SM502的恐怕很少，所以要找到答案，难。

已经可以读得到sm502的device id了,觉得应该硬件基本正常了吧?

刚才又测了一下,不排除硬件的问题.
把OS下载到没有SM502芯片的板子上,OS正常启动,没有出现调试信息错误.
而且我发现在有SM502芯片的板子上,进入OS后,一直不停的在调用OEMIdle()这个函数,请问在什么情况下会调用此函数呢?在没有SM502芯片的板子上OS起来之后是不调用这个函数的!难道受硬件影响?哪位高人能指点一下吗?

没做过，昨天刚发过一个关于显卡驱动的IC。
请问LZ这个驱动是自己写的？还是别人提供的？
