現在想把原本2.6.32內核的cmos攝像頭驅動移植到 2.6.35
參考了這網誌:
http://blog.csdn.net/csuwzc/article/details/6527372 把原本友善之臂提供的2.6.32 裡
s3c2440camif.c、s3c2440camif.h、s3c2440_ov9650.c、sccb.c、sccb.h 附製到 2.6.35裡'
之後
s3c2440camif.c 中的:
S3C2410_GPJ0 ->
S3C2410_GPJ(0)
S3C2410_GPJ1 ->
S3C2410_GPJ(1)
:
然後 添上kconfig 與 Make
編憶完並載上mini2440後 試圖開啟 Qtopia 裡的Cmos 攝像頭測試程序: 是言裝置有錯
comsole裡的打印錯誤是這樣:

那請問我要怎修改內核源代碼/改變配置 才能讓cmos攝相頭可以運行呢?
謝謝
