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 2.022.
For example, U222LBV2011_2016-01-29.zip which "LI" is acronym for prebuilt Linux Image, DualQuad means this image is fit for Dual Core/Quad Core.

BSP tarball

Unpack BSP tarball to home directory by performing the following command:
$ tar xvf ${BSP_TARBALL} -C ~/
(Every BSP with different version contains an unique folder, e.g. after unpacking 7420A1LBV5080_2016-03-09.tgz to home directory, the directory , ~/imx6LBV5080_2016-03-09 is the BSP's home folder.)
The description of some important folders list below:
sources/
meta-advantech/ : meta layer by Advantech
meta-fsl-*/ : meta layer by Freescale
fsl-setup-release.sh : to create one new build environment
setup-environment : to continue an exist build environment

Prebuilt image

Perform the following command to build one boot-up SD card
$ gunzip -c ${PREBUILT_IMAGE} | dd of=${SD_DEVICE} bs=1M

Build Instructions

To create one new build environment

Perform the following commands in terminal console
$ cd ${BSP_HOME}
$ MACHINE=${MC} source fsl-setup-release.sh -b ${BDIR} -e x11

# umount /media/mmcblk0p?
# cd /media/sda1
# dd if=${SDCARD_IMAGE} of=/dev/mmcblk0 bs=4M conv=fsync
# P2START=$(fdisk -lu | grep mmcblk0p2 | awk '{print $2}')
# echo -e "d\n2\nn\np\n2\n${P2START}\n\nw\n" | fdisk -u /dev/mmcblk0

Continue an exist build environment and build sdcard image

Setting up SDK

Please follow the section,To build toolchain installer, to build one toolchain installer
Perform the following command in terminal console
$ cd ${BSP_HOME}/BDIR}/tmp/deploy/sdk
$ sudo ./poky-eglibc-x86_64-fsl-image-qt5-cortexa9hf-vfp-neon-toolchain-${POKY}.sh
Enter directory or press Enter while following question shows up:
Setting up sdk 1.png
Just press Enter while following question shows up:
Setting up sdk 2.png

Setting up cross compiling environment

SDK has been set up (ref. Setting up SDK)
Perform the following command in terminal console
$ source /opt/poky/${POKY}/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi

Building & updating u-boot manually

To build u-boot

The cross compiling environment has been set up. (ref. Setting up cross compiling environment)
Make one copy from Yocto working directory
$ mkdir -p ~/code
$ pushd ${BSP_HOME}/${BDIR}/tmp/work/${MC}-poky-linux-gnueabi/
$ rm -rf ~/code/u-boot-imx
$ cp -a ./u-boot-imx/${UBOOT}/git ~/code/u-boot-imx
$ popd
Configure u-boot
$ cd ~/code/u-boot-imx
$ make distclean
$ make ${MX6PROC}${BOARD}${BOARD_REV}_${MEM_SIZE}_config
Start building u-boot
$ make -j4 LDFLAGS=
The two files, u-boot-crc.bin & u-boot-crc.bin.crc, are located in directory "~/code/u-boot-imx".

To update u-boot to target device

Perform the following command to transfer to exist boot-up SD card
$ dd if=u-boot_crc.bin.crc of=${SD_DEVICE} bs=512 seek=2 conv=fsync
$ dd if=u-boot-crc.bin of=${SD_DEVICE} bs=512 seek=3 conv=fsync
Make sure new u-boot does work then perform the following commands to transfer to on-board flash
# dd if=u-boot_crc.bin.crc of=/dev/mmcblk0 bs=512 seek=2 conv=fsync
# dd if=u-boot-crc.bin of=/dev/mmcblk0 bs=512 seek=3 conv=fsync

Building & updating kernel/modules/dtb manually

To build kernel/modules/dtb

The cross compiling environment has been set up. (ref. Setting up cross compiling environment)
Make one copy from Yocto working directory
$ mkdir -p ~/code
$ pushd ${BSP_HOME}/${BDIR}/tmp/work/${MC}-poky-linux-gnueabi/
$ rm -rf ~/code/linux-imx
$ cp -a ./linux-imx/${KERNEL}/git ~/code/inux-imx
$ popd
Configure linux kernel
$ cd ~/code/linux-imx
$ make distclean
$ make imx_v7_adv_defconfig
$ make menuconfig PKG_CONFIG_SYSROOT_DIR= PKG_CONFIG_PATH=
Start building linux kernel
$ make -j4 zImage LOADADDR=0x10008000 LDFLAGS=
The kernel image file, zImage, is located in the directory "./arch/arm/boot/".
Start building kernel modules
$ make -j4 modules LDFLAGS=
Copy all modules to a temporary rootfs directory, "~/temp/rootfs"
$ make modules_install INSTALL_MOD_PATH=~/temp/rootfs
Start building device tree blob
$ make -j4 ${IMX6PROC}-${BOARD}-${BOARD_REV}.dtb
The device tree blob, ${IMX6PROC}-${BOARD}-${BOARD_REV}.dtb, is located in the directory "./arch/arm/boot/dts/".

To update kernel/modules/dtb to target device

Copy zImage & ${IMX6PROC}-${BOARD}-${BOARD_REV}.dtb to the 1st partition of SD card
Copy modues to the 2nd partition of SD card.
Make sure all new linux kernel, device tree and kernel modules work well, then copy all of them to the on-board flash
