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.

Format and partition the target eMMC
Boot your target and:
$ fdisk /dev/mmcblk1 n p 1 <enter for default> <enter for default> t 83 w $ mkfs.ext4 /dev/mmcblk1p1 -Lrootfs
Install U-Boot and Linux Kernel images
