Hi All Uboot-(TEGRA users) , My name is Alexander almost done here !!! I Need you Help !!! to make the chromebook TegraTk1 model running Ubuntu-Xenial Mainline v4.4.0.70 distribution repo not ChromiumOS https://chromium.googlesource.com/chromiumos/third_party/kernel/+/v4.4.70

After I compiled the Kernel and zImage with this:

root@alarm:/# sudo make tegra_defconfig

root@alarm:/# sudo make menuconfig

root@alarm:/# make savedefconfig root@alarm:/# sudo make -j5 zImage dtbs modules

That doesn't matter for U-Boot though.

Second: I caught this file in attached Then I runing this command:

root@alarm:/# sudo /u-boot-tegra/b/nyan-big/tools/mkimage -D "-I dts -O dtb -p 2048" -f kernel.its vmlinux.uimg

Third:

file bootloader create with:

root@alarm:/#sudo dd if=/dev/zero of=bootloader.bin bs=512 count=1 -- > # dummy file

Fourth:

file config.txt create with:

echo 'console=tty0 init=/sbin/init root=PARTUUID=%U/PARTNROFF=1 rootwait rw noinitrd' > config.txt

and do this commands:

root@alarm:/#sudo make INSTALL_MOD_PATH=/lib/modules/4.4.0.70-ARCH modules_install

root@alarm:/#sudo make INSTALL_DTBS_PATH=/boot/dtbs" dtbs_install

root@alarm:/#sudo depmod -F System.map "4.4.0.70-ARCH"

Fifth :

After the files created I runnig this scripth file Kernel.sh below:

vbutil_kernel \ --pack vmlinux.kpart \ --version 1 \ --vmlinuz vmlinux.uimg \ --arch arm \ --keyblock /usr/share/vboot/devkeys/kernel.keyblock \ --signprivate /usr/share/vboot/devkeys/kernel_data_key.vbprivk \ --config config.txt \ --bootloader bootloader.bin

file vmlinux.kpart created

 Sixth : Put the file vmlinux.kpart in Kernel Partition /dev/sda6

root@alarm:/# sudo dd if=vmlinux.kpart of=/dev/sda6

  Seventh:

I copy this file vmlinux.kpart in /boot from my USB drive Rootfs partition and zImage file

Follow my USB /dev/sda parttion:

[aperfeito@alarm ~]$ sudo cgpt show /dev/sda [sudo] password for aperfeito: start size part contents 0 1 PMBR (Boot GUID: AD11024D-1016-B345-A21D-F7B823B0318A) 1 1 Pri GPT header 2 32 Pri GPT table 64 32768 6 Label: "KERN-A" Type: ChromeOS kernel UUID: D43B02E7-AF2D-3642-93D8-370D84193655 Attr: priority=0 tries=0 successful=0 65600 53542815 7 Label: "ROOT-A" Type: 0FC63DAF-8483-4772-8E79-3D69D8477DE4 UUID: A01D12A1-C0E2-D54C-B68A-6E24E3896AE2 61997023 32 Sec GPT table 61997055 1 Sec GPT header

What I have doing wrong ? Chromebook Bleps one attempt when using ctlr+U or more than 0 (zero) tries (Black Screen)

Have you tried the README.chromium steps? It actually looks very similar to what you have here. But it has been tested.
