Installing Custom Kernel on Nexus 5
-
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!

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!
