Installing Custom Kernel on Nexus 5

[altr0n]

Hello All,

First and foremost, I am following this guide: https://docs.ubuntu.com/phone/en/devices/porting-new-device

I have managed to build and install Ubuntu Touch on my Nexus 5. I would like to compile a custom kernel but I am running into some issues.

First, I cloned the source tree from here: https://github.com/ubports/android_kernel_lge_hammerhead

Then I placed the source in the kernel/lge/hammerhead directory

Next I modified the device/lge/hammerhead/BoardConfig.mk to build using the cyanogenmod_hammerhead_defconfig configuration as a test run.

Now, onto the problems...

The first problem that I had was that the kernel was not getting the device tree appended to it, I was able to copy the original tree from my working boot.img and that bypassed my "dtb not found errors"

Now when I try to run my new image, by running:

fastboot boot my-img.img

I simply hang at the google logo. I've not made any modifications to the kernel source or configuration yet there is still something that I am missing.

Does anyone have any suggestions or ideas? I'd really like to start on some kernel development and I'm not terribly familiar with the Android ecosystem.

Thanks!

@altr0n

I managed to get my own kernel compiled, the issue was that I did not have a console argument specified that I needed (I founded it on another post here)

console=tty0

Needed to be added to my kernel command line args.

Hope this is useful to someone in the future!
