I'm creating a camera driver for Android. I've got my mydriver.c file. Apparently I need to compile it into a .ko, is that right ?
And then to load it I should do a
#insmod ./mymodule.ko, will it work ?
Do I need to be root ? And how I put the .ko file on my Android tablet ?
回答1:
Yes, you need to be root. And, insmod ./yourmodule.ko should work fine.
回答2:
Are you trying to make this new camera work as a standard camera through Android's camera API?
In that case, unless your tablet has a particularly unusual configuration, simply installing a new kernel driver will do nothing. You still need an Android camera HAL module implementation that converts commands and data between your driver's kernel interface and Android's camera framework code.
