Simon,

    Hi , My Name is Alexander and i need some tip information about U-boot Board Nyan-Big to runinng Linux v4.4.x.x.

Can you please resend this to the U-Boot mailing list and cc me?

Thanks,
Simon

I compiled source 4.4.0.70 Ubuntu distribution in chroot environment in my chormebook Tegra Tk1.
After compilation the generated files were the following:

[aperfeito at alarm boot]$ ls -l
total 24992
-rw-r--r-- 1 root root    98874 Jul 13 14:54 config-4.4.70-ARCH
-rw-r--r-- 1 root root  8277506 Jul 13 14:54 initrd.img-4.4.70-ARCH
-rw-r--r-- 1 root root  2033244 Jul 13 14:54 System.map-4.4.70-ARCH
-rw-r--r-- 1 root root 15175680 Jul 13 14:54 vmlinuz-4.4.70-ARCH

I also compiled the u-boot-tegra in the same environment in chroot Ubuntu Xenial distribution these were compiled according to the email of Tom Warren send before

  Make 'nyan-big_defconfig' and everything ok as you see below the generated files:

[aperfeito at alarm u-boot-tegra]$ ls *.bin
u-boot.bin      u-boot-dtb-tegra.bin  u-boot-nodtb-tegra.bin
u-boot-dtb.bin  u-boot-nodtb.bin      u-boot-tegra.bin

Now is the tip I'm asking you:
I have two suggestions on how to put this in the KERNEL partition of my USB.
  My USB has two partitions
   To 1st. KERNEL Name with 16 megabytes of space dev / sda6
   A 2st.  ROOFS   Name approximately 29 Gigabytes of space where I worked to compile the UbuntuXenial and Uboot-Tegra srcs kernel as you see in the email.

Sugestion : 1
mkimage -D "-I dts -O dtb -p 2048" -f kernel.its vmlinux.uimg
  dd if=/dev/zero of=bootloader.bin bs=512 count=1
  vbutil_kernel \
    --pack vmlinux.kpart \
    --version 1 \
    --vmlinuz vmlinux.uimg \
    --arch arm \
    --keyblock kernel.keyblock \   --> How I do This  if necessary
    --signprivate kernel_data_key.vbprivk \  --> How I do This if necessary
    --config cmdline \ --> TXT file whit this config below
    --bootloader bootloader.bin

  *   kernel.its adjust to files below as given to te src kernel 4.4.0-70
./arch/arm/boot/dts/tegra124-nyan-blaze.dtb
./arch/arm/boot/dts/tegra124-nyan-big.dtb
  *
___________________________________________________TXT CONFIG FILE __________________________________________________
  *
console=tty1 init=/sbin/init root=PARTUUID=%U/PARTNROFF=1 rootwait rw noinitrd lsm.module_locking=0  ## OR ###
  *
initrd=/boot/initrd.img-4.4.0-ARCH console=ttyS0,115200n8 console=tty1 ignore_loglevel earlyprintk cgroup_enable=memory root=/dev/sda7

      ###  For config line need your sugestion with is the best.

Sugestion: 2

  I have to copy the kernel, generated initramfs, and dtb to the SDA6 partition and added the following kernel config to /dev/sda7/roofsparttion :/boot/extlinux/extlinux.conf

LABEL UbuntuXenial
 MENU LABEL UbuntuXenial on sda7 with 4.4 kernel
 LINUX /boot/vmlinuz-4.4.0
 FDT /boot/dtb/tegra124-nyan-big.dtb
 APPEND initrd=/boot/initrd.img-4.4.0-ARCH console=ttyS0,115200n8 console=tty1 ignore_loglevel earlyprintk cgroup_enable=memory root=/dev/sda7

How to make U-boot-Tegra now Work with Kernel 4.4.x.x as v3.10.x.x Kernels booting on USB.

Best Regards

See ‘nyan-big_defconfig’. Added Simon to CC as he’s used this build quite a lot.

HTH,

Tom
