Re: [android-kernel] Flashing Android Kernel -- do I need to compile the entire source tree?

If you are just creating a new boot.img you can run "make boot image"

Hi guys,

I have a toroplus (sprint galaxy nexus). I want to add a couple lines to my kernel config file --> compile my kernel, and load that on my device.

I've gotten to the stage where I can make a zImage. The AOSP guide tells me to copy that to /device/samsung/tuna/kernel and then to make the entire project.

Do I have to make the entire project if I just want the updated kernel? I also don't have the proprietary binaries -- since its sprint.

Help would be much appreciated.

Hi,

It is not necessary to build the all tree, but, from my experience, I did not found a standard

procedure to update a kernel in an Android system: I think this is a real pity!

Each device has some "features" which require to google for them and understand.

As example, if it can be useful, I flashed a new kernel on Acer Iconia A500:

See the section "Acer Iconia A500 kernel recompile"

No, you don't. Simply building zImage from your kernel, and then
repack it along with ramdisk.img. Make sure using right physical
offset of RAM, it is varied device by device.
