MV2440으로 공부하고 있습니다.
초보자입니다. ㅠ0ㅠ
로지텍 ㅋㅞㄱ캠 4000 프로를 장비에 인식 할려고 합니다.
많이 힘드네요 ;;;

시디 /MV2440_v1.4/source/Linux/mv2440_v2/240_320
mv2440_kernel2.4.20_r1.1.tar.gz mv2440_uboot_dev.tar.gz
를 이용해서 장치를 인식할려고 합니다.

먼제 USB usb-ohci-s3c2440.c 클럭을 수정하였습니다. 7->5 수정
커널의 drivers/char/Makefile 의 timer. 부분을 삭제하였습니다. 컴파일시 에러가 나서 ..
그리고 pwc파일을 수정하엿구여 4000을 인식하도록요
(ARM으로 배우는 임베디드 시스템 책을 참조하엿습니다. )

#make menuconfig
===================================================
Multimedia devices ---> M> Video For Linux
Video For Linux ---> [*] V4L information in proc filesystem

<*> Support for USB
[*] USB verbose debug messages

<M> OHCI (Compaq, iMacs, OPTi, SiS, ALi, ...) support

선택 ... CD에 있는 root.cramfs 에
/usr/lib/modules/2.4.20_elfin-d1.5/kernel 에 커널에 컴파일후 생긴
/lib/modules/2.4.20_elfin-d1.5/kernel/drivers을 복사해서 넣었습니다.

만들어진 zImage 와 cramfs를 장비에 포팅 시켯습니다.

부팅후
insmod -f videodev
insmod -f pwc
insmod -f pwcx-2.4.20.c (책에서 구한 파일을 강제로 올렸습니다. )

근데 인식이 안되더군요 ;;;;

dmesg 한 결과는

은 안올라 가더군요 ....

MV2440에 대한 자료가 너무 없는 것같습니다..
ㅠㅠ 도와주세요 ~!!
