Re: [android-building] How to upload a driver that I created to my device?

2019-07-19 Thread 'Dan Willemsen' via Android Building

Android (as AOSP) does not build the kernel along with the platform code --
it's expected to be delivered as a prebuilt. So setting KERNEL_DEFCONFIG
won't do anything.

Re: [android-building] SDK building - development/build/sdk.atree - couldn't locate source file error

2019-07-19 Thread 'Dan Willemsen' via Android Building

Building the sdk generally requires using the 'sdk' product when calling
lunch -- it looks like that's why you were building a bunch of tools
independently.

I wouldn't be surprised if the sdk generation code didn't support
OUT_DIR(/OUT_DIR_COMMON_BASE) that was anything other than "out".

Re: [android-building] How to upload a driver that I created to my device?

2019-07-19 Thread abhishekkumardwiv...@gmail.com

If you have full source code of Android stack with the kernel then you can
check at AndroidBoard.mk file which will address the config file used for
kernel compilation. If you want to compile only kernel then you can do
something like:
$ make -j4 KERNEL_DEFCONFIG=xyz_defconfig
Here the xyz_defconfig is the file name which you might have found in
AndroidBoard.mk.
This is the usual way but I am not sure about the device you are using.
