1.1 Приветствие:
Добро пожаловать в Freescale QorIQ SDK (эталонный дистрибутив)
Yocto Project имеет обширную документацию по OE, включая справочное руководство, которое можно найти по адресу:
     http://yoctoproject.org/documentation
Для получения дополнительной информации об OpenEmbedded посетите их веб-сайт:
     http://www.openembedded.org/
Теперь вы можете запустить 'bitbake '
    fsl-image-networking
    fsl-image-networking-full


2. Производим сборку 
cd ~/yocto-sdk
. ./setup-env -m ls1046afrwy
!!! fsl-image-networking - офф образ nxp
!!! fsl-image-networking-full  - офф образ nxp
!!! core-image-sato - будет собран дистрибутив с GUI
!!! core-image-base - базовая версия
!!! core-image-minimal - что то там минимальное
!!! ovs-dpdk - что то там с openvswitch и dpdk
 
bitbake fsl-image-networking

Настройка  fsl-image-multimedia-full убираем x11 и сборка
vim conf/local.conf 
-------------------
DISTRO_FEATURES_remove = " x11" <--- убираем #, раскомментировать строку, тем самым сборка будет без x11
-------------------
Производим сборку:
bitbake fsl-image-multimedia-full

Сборка под sdcard:
wic create ls104x-uboot-bootpart --no-fstab-update -e fsl-image-networking

Booting board with full rootfs from large storage device

1. Prepare the media (SD/USB/SATA) and format it to ext2 format.
2. Mount the ext2 partition, extract a full rootfs into this partition, and unmount the partition.
3. Power up or reset the board.
4. Press a key on the keyboard when prompted on the terminal to enter into the U-Boot command line.
5. Set up the environment in U-Boot using command described in the table below.

LS1046ARDB and  FRWY-LS1046A

Program TF-A binaries on NAND flash:

1. Boot the board from default bank.
2. Flash bl2_nand.pbl to NAND flash:
=> tftp 82000000 $path/bl2_nand.pbl
=> nand erase 0x0 $filesize;nand write 0x82000000 0x0 $filesize;
3. Flash fip_uboot.bin to NAND flash:
=> tftp 82000000 $path/fip_uboot.bin
=> nand erase 0x100000 $filesize;nand write 0x82000000 0x100000 $filesize;
4. Boot the board from NAND flash. The board boots with TF-A.

Question:

Question 1: How can I compile ATF with OPTEE?
Answer: For compiling ATF with OPTEE, add the below line in your conf/local.conf file:
DISTRO_FEATURES_append = " optee"

Question 2: How can I compile ATF with RCW image that is different from default image?
Answer: Modify RCWNOR or RCWSD and RCWNAND in .conf file. 
For example, update ls1043ardb.conf file in meta-freescale layer as follows:
RCWNOR ?= "RR_FQPP_1455/rcw_1600"

Question 3: How can I add custom additional packages to default rootfs?
Answer: Set IMAGE_INSTALL_append in the conf/local.conf file.
