It would help if you put yourcode somewhere and ask people for taking a look on it. Also, as Patrick and Luca said, the better environment for you todevelop a new driver is using a copy of v4l-dvb + your driver. Assumingthat your driver is called "mydriver", you need just to: a) create a newer dir with your driver: /linux/drivers/media/dvb/mydriverb) Under /linux/drivers/media/dvb/mydriver: create a Kconfig and a Makefile You may use another Kconfig/Makefile as example (for example, pluto2)c) Add your driver directory at /linux/drivers/media/dvb/Makefile: obj-y := dvb-core/ frontends/ ttpci/ ttusb-dec/ ttusb-budget/ b2c2/ bt8xx/ cinergyT2/ dvb-usb/ pluto2/ mydriver/ d) Add a source line for your driver at /linux/drivers/media/dvb/Kconfig: source "drivers/media/dvb/mydriver/Kconfig" After that, you will be able to use v4l-dvb makefile to compile yourdriver. With make helpyou'll see some useful syntax that may help your development.
