Prerequisites
To install Docker Engine on your platform
- Please refer to Docker Installation Guide for details
To pull ubuntu 12.04 image from Docker Hub & run the image
$ docker pull advrisc/u12.04-quarklbv2
$ docker run --name quarkLBV2011 -it advrisc/u12.04-quarklbv2 /bin/bash
To copy BSP from local filesystem to the container
$ docker cp ${BSP_PACK} quarkLBV2011:/home/adv/
To copy files from the container's filesystem to local machine
$ docker cp quarkLBV2011:/home/adv/${BSP_HOME}/${BDIR}/tmp/deploy/images/quark ~
Introducing BSP
- The BSP is based on Yocto Project with Intel enhanced features for Quark, plus specific target board features from Advantech Inc..
Naming Rule
- The tarball/prebuilt image name is consist of the model name followed by "LB" or "LI" plus version number and released date.
- For example, U222LBV2011_2016-01-29.zip which "U222" stands for UBC-222, "LB" is acronym of Linux BSP, "V2011" stands for Version 2.011.
- For example, U222LIV2011_quark_2016-01-29.zip which "LI" is acronym for prebuilt Linux Image.
BSP pack
- Using one of the following ways
- Unpack BSP pack to home directory
$ unzip ${BSP_PACK} -d ~/
- The description of some important folders list below:
- ${BSP_HOME}/
- meta-advantech/: meta layer by Advantech
- meta-intel-*/: meta layer by Intel
- setup.sh: to setup one new build environment(read this if the BSP is got from GitHub)
- oe-init-build-env: to initiate build environment
- ${BSP_HOME}/
Prebuilt image pack
*** read this if the BSP is got from GitHub ***
- Perform the following command to unpack prebuilt-image-pack to home directory
$ unzip ${IMAGE_PACK} -d ~/
- Prepare one FAT32 formatted SD card, and mount it to mount point
$ cp -a ${IMAGE_DIR}/sdcard/* ${SD_MOUNT}/
Build Instructions
Please refer to this link to set Git configuration first.
To create one new build environment
- Perform the following commands in terminal console
$ cd ${BSP_HOME}
$ ./setup.sh
(read this if the BSP is got from GitHub)$ BOARD=${BOARD_ID} source ./oe-init-build-env ${BDIR}
To continue an exist build environment
- Perform the following commands in terminal console
$ cd ${BSP_HOME}
$ BOARD=${BOARD_ID} source ./oe-init-build-env
To build all image files
- To create/continue a build environment
- Perform the following command in terminal console
$ bitbake image-full
- The following files will be located in directory "./tmp/deploy/images/quark" while building process finished successfully.
- boot/grub/grub.conf
- bzImage
- core-image-minimal-initramfs-quark.cpio.gz
- grub.efi
- image-full-quark.ext3
To build toolchain installer
- To create/continue a build environment
- Perform the following command in terminal console
$ bitbake image-full -c populate_sdk
- The installer, iot-devkit-glibc-x86_64-image-full-i586-toolchain-${POKY}.sh, will be located in the directory "./tmp/deploy/sdk".
To build grub individually
- To create/continue a build environment
- Perform the following command in terminal console
$ bitbake grub
- The file, grub.efi, will be located in directory, ./tmp/deploy/images/quark.
To build linux kernel individually
- To create/continue a build environment
- Perform the following command in terminal console
- to show up menuconfig
$ bitbake linux-yocto-quark -c menuconfig
- to do build
$ bitbake linux-yocto-quark
- to show up menuconfig
- The file, bzImage, will be located in directory, ./tmp/deploy/images/quark.
To build initramfs individually
- To create/continue a build environment
- Perform the following command in terminal console
$ bitbake core-image-minimal-initramfs
- The file, core-image-minimal-initramfs-quark.cpio.gz, will be located in directory, ./tmp/deploy/images/quark.
Customization
Setting up SDK
- Please follow the section,to build toolchain installer, to build one toolchain installer first.
- Perform the following command in terminal console
$ cd ${BSP_HOME}/${BDIR}/tmp/deploy/sdk
$ sudo ./iot-devkit-glibc-x86_64-image-full-i586-toolchain-${POKY}.sh
- Enter directory or press Enter while following question shows up:
Enter target directory for SDK (default: /opt/iot-devkit/1.7.2):
- Just press Enter while following question shows up:
You are about to install the SDK to "/opt/iot-devkit/1.7.2". Proceed[Y/n]?
- While following message shows up means the SDK is ready.
Extracting SDK...done Setting it up...done SDK has been successfully set up and is ready to be used.
Setting up cross compiling environment
- SDK has been set up (ref. Setting up SDK)
- Perform the following command in terminal console
$ source /opt/iot-devkit/${POKY}/environment-setup-i586-poky-linux
