Overview

Ubuntu Linaro Alip is pre built file system. For more information Ubuntu based Rootfs provided by Linaro. Variscite used linaro-vivid-alip-20151215-714 image added Vivante Graphic acceleration and compile the GStreamer with i.MX6 support.

Create Ubuntu Alip SDCARD is prerequisite step. Please make sure you run it and have a bootable Ubuntu SDCARD as described in the linked WIKI.

The steps require to build an Bootable SDCARD:

Build Ubuntu Alip NFS. Build Ubuntu Alip NFS
Created Ubuntu Alip bootable SDCARD. Create Ubuntu Alip SDCARD
Copy required file to your SDCARD
Boot your target from SDCARD
Format and partition the target eMMC
Install U-Boot and Linux Kernel images
Install the root file system
Deploy the kernel modules
Deploy the Wi-Fi modules and firmware

Copy required file to your SDCARD

Note:
Make sure you built U-Boot for NAND.

Plug-In the bootable SDCARD
$ cd  ~/var-som-mx6-alip/
$ mkdir -p /media/rootfs/opt/images/Alip
$ sudo cp uboot-imx/SPL /media/rootfs/opt/images/Alip
$ sudo cp uboot-imx/u-boot.img /media/rootfs/opt/images/Alip
$ sudo cp linux-2.6-imx/arch/arm/boot/uImage /media/rootfs/opt/images/Alip
$ sudo cp linux-2.6-imx/arch/arm/boot/dts/*var*.dtb /media/rootfs/opt/images/Alip
$ sudo cp ~/Downloads/linaro-alip-20151215-v1.tar.bz2  /media/rootfs/opt/images/Alip

Format and partition the target eMMC

Boot your target and:

$ fdisk /dev/mmcblk1

w
$ mkfs.ext4 /dev/mmcblk1p1 -Lrootfs

Install U-Boot and Linux Kernel images

Note:
Make sure you built U-Boot for NAND.

$ flash_erase /dev/mtd0 0 0
$ kobs-ng init -x SPL --search_exponent=1 -v > /dev/null
$ flash_erase /dev/mtd1 0 0
$ nandwrite -p /dev/mtd1 u-boot.img
$
$ flash_erase  /dev/mtd2 0 0
$ nandwrite -p /dev/mtd2 uImage
$ nandwrite -p /dev/mtd1 -s 0x1e0000 imx6q-var-som.dtb
$ sync

Install the root file system

$ mkdir tmp
$ mount /dev/mmcblk1p1 tmp/
$ tar xf linaro-alip-20151215-v1.tar.bz2  -C tmp/
$ umount tmp
$ rm -rf tmp

Deploy the kernel modules

$ cd ~/var-som-mx6-alip/linux-2.6-imx
$ sudo make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- modules_install INSTALL_MOD_PATH=/media/rootfs/

Deploy the Wi-Fi modules and firmware

$ cd ~/var-som-mx6-alip/build-utilites
$ gedit setup-env
set:
export ROOTFS=/media/rootfs

$ ./sudo_build_wl18xx.sh modules
$ ./sudo_build_wl18xx.sh firmware
$ ./sudo_build_wl18xx.sh bt-firmware
$ sudo umount /dev/sdxxx*

u-boot paramters

echo "Please stop at u-boot and set enviroment" echo "setenv bootargs console=ttymxc0,115200 video=mxcfb1:off root=/dev/mmcblk1p1 rootwait rw" echo "saveenv"
