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 Torvaldsās 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 onesā¦
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 dfdcda0ā¦ec2731d 100644
ā a/drivers/Makefile
+++ b/drivers/Makefile

###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 āyā for any question asked related to amlogic config option !
###Get ubuntu xenial base tarballā¦
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 modulesā¦
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 installsā¦
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 buildā¦
sudo chroot /mnt/kvimrootfs mkinitramfs -o /boot/initrd.img 4.13.0-rc1
will output lots of nvida warnings and one ERRORā¦
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 rootfsā¦
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

###nb: DOES THIS EVEN SEEM CORRECT FOR emmc ?
Then, flash the resulting update.img
Alas,
during burning of update.img, I get blocking errors
