I'll add more data about my problem, and what I already tested: I'm working over a Nexus 5 (MSM architecture, Linux 3.4.0 based). The .config used is the one by default (hammerhead_defconfig). When the kernel is booted, it only shows the Google screen, and stops there, forever.
I tried (with a working boot image) changing the 'console' parameter when generating the image with mkbootimg (tty, tty0, ttyHSL0), and I tried with different .config options as MSM_SERIAL_DEBUGGER (compilation error), FIQ_DEBUGGER (compilation error) and SERIAL_MSM (compiled, but no difference). I was looking for the addition of a device in my computer. 2013/12/18 Marc Marí <5.markm...@gmail.com> > Hello > > I am new to Android and to Kernel development, but I would like to test > some things.
