Hi Tom,

I Try to running Linux Mainline Kernel V 4.4.0 to boot up in my chromebook using Ctrl+U in dev mode and using USBv3.0 drive as a drive.

I using this command:

aperfeito@alarm:/# sudo make -j5 uImage UIMAGE_LOADADDR=0x82408000 dtbs modules

In doc in http://git.denx.de/?p=u-boot.git;a=blob_plain;f=doc/README.chromium;hb=HEAD

SAY:

1. Patch U-Boot

Open include/configs/tegra124-common.h

Change:

#define CONFIG_SYS_TEXT_BASE 0x80110000

to:

#define CONFIG_SYS_TEXT_BASE 0x81000100 I did this and compiled U-boot.... OK

And after copy the files generated by Kernel compilation (uImage) Mychromebooks BLEPS everytime when try to boot with this files generated: 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 \ # console=tty0 init=/sbin/init root=PARTUUID=%U/PARTNROFF=1 rootwait rw noinitrd --bootloader bootloader.bin #dummy

file vmlinux.kpart created

Put the file vmlinux.kpart in Kernel Partition /dev/sda6 and file uImage compiled in /boot also dtb(s) tegra124-nyan-big and -blaze.dtbs

My USB: 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

Sorry, Alexander. I’m not sure what you are asking me to do here.

I’ve got an action-item to look at Simon’s Nyan-big patches, but haven’t had a chance to do that this week. I’ll try to get to it early next week, and if everything looks good I’ll post a PR to bring those patches in to u-boot/tegra.

Hope this helps,

Tom

There is a series which shows how to do this for tegra and rockchip. It is at u-boot-dm/chain-working and you can find a README there as well.

The series has not been applied yet - I think it is in Tom Warren's queue?

Regards, Simon [...]

Hi Alexandre,

[...]

...

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@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@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.

There is a series which shows how to do this for tegra and rockchip. It is at u-boot-dm/chain-working and you can find a README there as well.

The series has not been applied yet - I think it is in Tom Warren's queue?
