[Raspberry Pi General] marcosx86:
Pursuing the full build, I've managed to completely do it, but now I'm stuck on starting up the Android environment. Perhaps I'm missing something. This is my local_manifest.xml:

For initializing my repo, I used LineageOS's cm-11.0 branch. Also, did some small tuning on the kernel/rpi config (added verbosity, etc), and plugged in trevd's device_broadcom_rpi's BoardConfig.mk's Kernel settings to comply on my changes.

But this config.txt is not working. Modified ramdisk.img's loglevel (init.rc) to 8 but not a single Android line, except kernel's. This is the config.txt I'm using:

hdmi_drive=2
config_hdmi_boost=5
hdmi_group=1
hdmi_mode=4
hdmi_force_hotplug=1
disable_overscan=1

framebuffer_width=1280
framebuffer_height=720
framebuffer_depth=16
framebuffer_ignore_alpha=1

kernel=kernel
#cmdline="console=tty1 console=ttyAMA0,115200 no_console_suspend dwc_otg.lpm_enable=0 androidboot.carrier=wifi-only"
cmdline="dwc_otg.lpm_enable=0 console=tty1 rootwait androidboot.carrier=wifi-only root=/dev/ram0"
device_tree=bcm2708-rpi-b-plus.dtb
initramfs ramdisk.img

avoid_warnings=2

Perhaps the kernel can't mount/find the initial root partition (ramdisk.img?)?

Any help on booting this thing is appreciated :D
