VAR-SOM-MX6 - Ubuntu Linaro Alip-20151215 Flash your target from NET

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.

Build Ubuntu Alip NFS is prerequisite step. Please make sure you run it and have a complete NFS build directory as described in the linked WIKI. Also make sure you target is booted from NFS.

The steps require to build an Bootable SDCARD:

Build Ubuntu Alip NFS. Build Ubuntu Alip NFS
Boot your Ubuntu Alip with TFTP and mount your file system over NFS. Build Ubuntu Alip NFS
Copy required file to your NFS directory
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 NFS directory

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

$ cd  ~/var-som-mx6-alip/
$ sudo cp uboot-imx/SPL rootfs/root
$ sudo cp uboot-imx/u-boot.img rootfs/root
$ sudo cp linux-2.6-imx/arch/arm/boot/uImage rootfs/root
$ sudo cp linux-2.6-imx/arch/arm/boot/dts/*var*.dtb rootfs/root
$ sudo cp ~/baba/Downloads/
$ sudo cp ~/baba/Downloads/linaro-alip-20151215-v3.tar.bz2  rootfs/root/

Format and partition the target eMMC

Boot your target and:

$ fdisk /dev/mmcblk1

$ 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-v3.tar.bz2  -C tmp/
$ umount tmp
$ rm -rf tmp

Deploy the kernel modules

Deploy the Wi-Fi modules and firmware

u-boot paramters
