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, U222LBV2011_quark_2016-01-29.zip which "LI" is acronym for prebuilt Linux Image.
BSP pack
- Unpack BSP pack to home directory by performing the following command:
$ unzip ${BSP_PACK} -d ~/
- The description of some important folders list below:
- $BSP_HOME/meta-clanton_v1.2.0
- meta-advantech/ : meta layer by Advantech
- meta-intel-*/ : meta layer by Intel
- setup.sh : to setup one new build environment
- oe-init-build-env : to initiate build environment
- $BSP_HOME/meta-clanton_v1.2.0
Prebuilt image pack
- Perform the following command to unpack prebuilt-image-pack to home directory
$ unzip ${PREBUILT_IMAGE_PACK} -d ~/
- Prepare one FAT32 formatted SD card, and mount it to mount point
$ cp -a ${PREBUILT_IMAGE_DIR}/sdcard/* ${SD_MOUNT}/

$ 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
