DIY mainline kernel (4.12)+ ubuntu base 17.04 (zesty) for vim pro and EMMC install

Ok,
here is the latest list of all the steps I followed to build an intermediate target : khadas UBOOT + linux 4.12 mainline + xenial on VIM pro

###Prepare project tree

cd ~ install -d ~/project/khadas/ubuntu/{linux,rootfs,archives/{ubuntu-base,debs,hwpacks},images,scripts} cd ~/project/khadas/ubuntu/

###Clone the utils repository to fetch the tools for development:
git clone https://github.com/khadas/utils.git

###Download the U-Boot source tree, take a notice of the branch ubuntu as the option when you run git clone:

git clone https://github.com/khadas/u-boot -b ubuntu

###Edit and change bootargs in
~/project/khadas/ubuntu/u-boot/board/khadas/configs/kvim.h

replace
"root=LABEL=ROOTFS rootflags=data=writeback rw logo=osd1,loaded,0x3d800000,1080p60hz vout=1080p60hz,enable hdmimode=1080p60hz console=ttyS0,115200n8 console=tty0 no_consol
with
"root=/dev/mmcblk0p1 rootflags=data=writeback rw rootwait console=ttyAML0,115200 console=tty0 earlyprintk=aml-uart,0xc81004c0 fsck.repair=yes governor=ondemand no_console_suspend elevator=noop\0" \

###Build UBOOT for Khadas VIM:

cd ~/project/khadas/ubuntu/u-boot/
make kvim_defconfig
make -j4 CROSS_COMPILE=aarch64-linux-gnu-

Generated files:
fip/u-boot.bin: bootloader blob for eMMC

###Build linux kernel mainline:

Fetch the linux mainline repository from Linus Torvalds’s GitHub repository:

cd ~/project/khadas/ubuntu/linux
git init
git remote add torvalds https://github.com/torvalds/linux.git
git fetch torvalds master
git checkout remotes/torvalds/master

###Patch a few files
Retrieve this patchset

Do a tar xzf on it, this will create a patches/ folder containing 7 .patch files

In that folder, replace 0004*patch with this newer version

Assuming that the patches are in ~/Downloads/patches/
apply these 4 ones…

cd ~/project/khadas/ubuntu/linux
git am ~/Downloads/patches/0001-CONFIG-add-kvim_defconfig-from-defconfig-for-VIM.patch
git am ~/Downloads/patches/0002-CONFIG-config-wifi-ethmac.patch
git am ~/Downloads/patches/0003-DTS-disable-scpi_clocks.patch
git am ~/Downloads/patches/0004-EMMC-add-EMMC-partitions-porting-from-amlogic-linux-.patch
git am ~/Downloads/patches/0006-CONFIG-remove-some-unused-modules.patch

###Patch ~/project/khadas/ubuntu/linux/drivers/Makefile manually

diff --git a/drivers/Makefile b/drivers/Makefile
index dfdcda0…ec2731d 100644
— a/drivers/Makefile
+++ b/drivers/Makefile
@@ -182,3 +182,4 @@ obj-$(CONFIG_FPGA) += fpga/
obj-$(CONFIG_FSI) += fsi/
obj-$(CONFIG_TEE) += tee/
obj-$(CONFIG_MULTIPLEXER) += mux/
+obj-$(CONFIG_AMLOGIC_DRIVER) += amlogic/

###Building kernel, dtb & modules

cd ~/project/khadas/ubuntu/linux
touch .scmversion
make -j4 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- Image amlogic/meson-gxl-s905x-khadas-vim.dtb modules

NB=> Answer ‘y’ for any question asked related to amlogic config option !

###Get ubuntu xenial base tarball…

cd ~/project
sudo wget  http://cdimage.ubuntu.com/ubuntu-base/releases/16.04.2/release/ubuntu-base-16.04.2-base-arm64.tar.gz

Now get inspired from [How to] Debian Stretch + Linux 4.9 from scratch (w/download, EMMC only)
and
###Build rootfs
cd ~/project
truncate --size 1300M rootfs.img
mkfs.ext4 -F -L ROOTFS rootfs.img
sudo mkdir /mnt/kvimrootfs
sudo mount -o loop rootfs.img /mnt/kvimrootfs
cd /mnt/kvimrootfs
sudo rm -rf * lost+found/

###expand xenial in this new rootfs
cd /mnt/kvimrootfs
sudo tar -xzf ~/project/ubuntu-base-16.04.2-base-arm64.tar.gz

###install kernel modules…
cd ~/project/khadas/ubuntu/linux
sudo make -j4 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- modules_install INSTALL_MOD_PATH=/mnt/kvimrootfs

last output line will show
DEPMOD 4.12.0
(or 4.13.0-rc1 as of 22july17)

###prepare for chroot and apt installs…
sudo apt-get install qemu qemu-user-static binfmt-support debootstrap

###Setup the Chroot environment:
sudo cp -a /usr/bin/qemu-aarch64-static /mnt/kvimrootfs/usr/bin/
sudo mount -o bind /proc /mnt/kvimrootfs/proc
sudo mount -o bind /sys /mnt/kvimrootfs/sys
sudo mount -o bind /dev /mnt/kvimrootfs/dev
sudo mount -o bind /dev/pts /mnt/kvimrootfs/dev/pts

User account

USERNAME=khadas
PASSWORD=khadas
sudo chroot /mnt/kvimrootfs adduser --disabled-password --gecos "" $USERNAME
sudo chroot /mnt/kvimrootfs usermod -aG sudo $USERNAME
echo "$USERNAME:$PASSWORD" | sudo chroot /mnt/kvimrootfs chpasswd

Serial console

sudo chroot /mnt/kvimrootfs ln -s /lib/systemd/system/serial-getty\@.service /etc/systemd/system/getty.target.wants/serial-getty@ttyS0.service

misc Packages

sudo chroot /mnt/kvimrootfs bash -c "echo 'nameserver 8.8.8.8' > /etc/resolv.conf"
sudo chroot /mnt/kvimrootfs apt update
sudo chroot /mnt/kvimrootfs apt install --yes --no-install-recommends sudo fbset network-manager initramfs-tools openssh-server
sudo chroot /mnt/kvimrootfs apt install --yes --no-install-recommends ifupdown net-tools udev vim ssh ping

Hostname

sudo chroot /mnt/kvimrootfs bash -c "echo ivnKhadasVIM > /etc/hostname"

Ramdisk build…

sudo chroot /mnt/kvimrootfs mkinitramfs -o /boot/initrd.img 4.13.0-rc1

will output lots of nvida warnings and one ERROR…
W: Possible missing firmware /lib/firmware/nvidia/gk20a/fecs_data.bin for module nouveau
Unsupported ioctl: cmd=0x5331

###Handle new initrd.img
sudo mv /mnt/kvimrootfs/boot/initrd.img ~/project

###Clean rootfs…
sudo chroot /mnt/kvimrootfs apt clean
sudo rm -f /mnt/kvimrootfs/usr/bin/qemu-aarch64-static
cd ~/project/khadas/ubuntu
sudo cp linux/arch/arm64/boot/dts/amlogic/meson-gxl-s905x-khadas-vim.dtb /mnt/kvimrootfs
sudo sync
sudo umount /mnt/kvimrootfs/dev/pts
sudo umount /mnt/kvimrootfs/dev
sudo umount /mnt/kvimrootfs/sys
sudo umount /mnt/kvimrootfs/proc
sudo umount /mnt/kvimrootfs

###produce ramdisk.img
cd ~/project
khadas/ubuntu/utils/mkbootimg --kernel khadas/ubuntu/linux/arch/arm64/boot/Image --ramdisk initrd.img -o ramdisk.img
rm -f initrd.img

###Pack a logo
cd ~/project
wget https://meyer.io/dl/khadasvim/debian-bootup.bmp
khadas/ubuntu/utils/logo_img_packer debian-bootup.bmp logo.img
rm -f debian-bootup.bmp

###Fix the symlinks in image_upgrade/
cd ~/project/images_upgrade
ln -f -s ~/project/khadas/ubuntu/u-boot/fip/u-boot.bin u-boot.bin
ln -f -s ~/project/khadas/ubuntu/u-boot/fip/u-boot.bin.sd.bin u-boot.bin.sd.bin

ln -f -s ~/project/khadas/ubuntu/linux/arch/arm64/boot/dts/amlogic/meson-gxl-s905x-khadas-vim.dtb kvim.dtb

###Pack the system update image…
cd ~/project
khadas/ubuntu/utils/aml_image_v2_packer -r images_upgrade/package.conf images_upgrade update.img

###nb: DOES THIS EVEN SEEM CORRECT FOR emmc ?

Then, flash the resulting update.img

Alas,
during burning of update.img, I get blocking errors

Hi:
Have this error been fixed? or any update???

HI, not fixed yet, but I have been told a few hints on how to solve the issue… stay tuned

another hint: Add INSTALL_MOD_STRIP=1 to your make modules line.
It will strip the modules size down to about 1/10th the size!

Ok, almost done !
I finally managed to build from scratch u-boot + 4.12rc6 + zesty :hugs::star_struck::checkered_flag:
here are traces for the very 1st booting of my system on the vim pro …
Here are the few errors I noticed:
[ 0.000000] efi: Getting EFI parameters from FDT:
[ 0.000000] efi: UEFI not found.
and
[ 0.183345] dmi: Firmware registration failed.
and

thanks all for your likes,
I now would like to go one step ahead:
port the customization done by numbqq on 4.12-rc6 to 4.13-rc*

the task seems huge,
what I have at hand is a patchset, source repos from @numbqq, khadas, @umiddelb, @narmstrong, torvalds…

I cloned torvalds 4.12-rc6 sources…

GIT_OPT="–depth 1 --single-branch"
git clone $GIT_OPT -b 4.12-rc6 https://github.com/torvalds/linux.git linux-kernel-linus412-rc6

I cloned numbqq’s repo…

git clone $GIT_OPT -b 4.12-rc6 https://github.com/numbqq/linux.git linux-kernel-numbqq

and I meld compared the 2 trees…

meld linux-kernel-linus412-rc6/ linux-kernel-numbqq/

…enjoy the number of differences !

In meld GUI, I did notice most of the patchset content, but also things unfortunately not present in the patchset!

I will implement all the needed changes related to emmc as a shell script using only cp and sed commands,
but for now, I did just manually synced them by clicking here and there in meld and only for things I consider directly as related to EMMC

to be continued…

done sofar:

  • include in a shell script all the supposed patches needed on 412rc6 pure mainline source tree ;
  • build a kernel from that,
  • use this kernel image, dtb and modules to rebuild a system that boots properly

tbc…

hey guys,
how about this ? a mainline 4.12.0 kernel, patched on the fly with a shell script (and using only sed, ed and cp), which successfully boots on a kvim pro :checkered_flag::hugs::blush::1st_place_medal: and says…

I admit not everything works right away :worried:,
but at least we have a working process to produce, test, fix, iterate on mainline (4.12)
and some hope that the process can also be applied (with caution) to any 4.13 release candidate as well.
I consider to publish my toolset soon, if someone is interested enough to test and upgrade it :notes::surfing_man::men_wrestling::seedling:

Publish it please when my Khadas will arrive i want to test it.

Ok, 1st annoying issue was ethernet, now it is fixed, after a few additional tweaks to the defconfig file :sweat_smile:
and here is the dmesg trace
https://pastebin.com/je7rYFVD
Let’s see if there is something looking a bit wrong in it, I can see

[ 0.181379] dmi: Firmware registration failed.

but they seem ok enough for me for now, what do you think, guys ?

Next issue to solve :
get the hdmi monitor display the boot trace and then a login prompt (i know, no usb and keyboard support yet in mainline 4.12, but I just get prepared for some future good news)
it does display only a static logo for now;

Can anyone or @numbqq, @Gouwa give me a hint please, tks !

Hi ravelo,

You mean no boot trace and login prompt with 4.12.7/16.04.3 ?

yes Nick,
but i think it is because I removed
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_FB=y
from my defconfig…
I am rebuilding with them now…

for the info, boot trace and login prompt ok on serial console, which was my primary concern

Hi ravelo,

Yes, CONFIG_FRAMEBUFFER_CONSOLE is needed if you want to output message to HDMI screen.

Alas, that changed nothing,
still no boot trace and login prompt on my hdmi monitor :face_with_raised_eyebrow:

sudo /bin/fbset says “no /dev/fb0” !

What is your defconfig? Maybe drm module have not been loaded. Check about CONFIG_DRM,CONFIG_DRM_MESON and CONFIG_DRM_MESON_DW_HDMI. And try modprobe meson-drm to load drm module.

not there yet,
I did not build it as module,
CONFIG_DRM_MESON_DW_HDMI=y
