[U-Boot] Compiling Mainline Kernel v4.4.70 Stable to ChormeBook Nvidia Tegra TK1 (Ubuntu-Xenial) -Uboot Not Booting (BlackScreen)

[Alexandre N. Perfeito]

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 at alarm:/# sudo make tegra_defconfig

root at alarm:/# sudo make menuconfig

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


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


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

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

 root at 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 at 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 at alarm ~]$ sudo cgpt show /dev/sda
[sudo] password for aperfeito:
       start        size            part           contents

                                                          Attr: priority=0 tries=0 successful=0
       65600    53542815     7             Label: "ROOT-A"

                                                         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)


Cheers


Perfeito, Alexander
