1 Setup Build Environment

1.1 The Ubuntu release

The Ubuntu 14.04 64 bit release is the recommend developing environment. You might be able to use the later Ubuntu release as your developing environment as well.

1.2 Install the Compile Toolchain

1.2.1 Download the necessary toolchains from Realtek FTP site.

ToolChain Name	FTP Site	Remark
icedtea-bin-7.2.4.7.tgz	ftp://rtkwifidisplay:7Fc4dH@ftp3.realtek.com/1295ToolChain/icedtea-bin-7.2.4.7.tgz	Build Android
JAVA.sh	ftp://rtkwifidisplay:7Fc4dH@ftp3.realtek.com/1295ToolChain/JAVA.sh	Set JAVA Tool
android-ndk-r9c.tgz	ftp://rtkwifidisplay:7Fc4dH@ftp3.realtek.com/1295ToolChain/android-ndk-r9c.tgz	Build DvdPlayer

1.2.2 Toolchain installation (instructions in GREEN)

a) Untar ‘icedtea-bin-7.2.4.7.tgz’ to the Home Directory of Users.

b) Untar ‘android-ndk-r9c.tgz’ to ‘/opt’

sudo ln -s android-ndk-r9c android-ndk /*Make a static link*/

c) Install the toolchain of uboot

sudo apt-get install u-boot-tools

sudo apt-get install libssl-dev

Install libswitch-perl to pack the secure install.img

#sudo apt-get install libswitch-perl

d) Copy ‘JAVA.sh’ to the Home Directory of Users

e) Re-Link the ‘sh’ in ‘/bin’

cd /bin

sudo unlink sh

sudo ln –s bash h

f) sudo apt-get install bison

g) sudo apt-get install libxml2-utils

h) add move

apt-get install g++-multilib gcc-multilib lib32ncurses5-dev lib32readline-gplv2-dev lib32z1-dev

2 Build Secure install.img

2.1 Bootcode -加密的请使用附的大客户版本LK

Place the corresponding HW Setting to "tools/flash_writer/image/hw_setting/rtd1295/demo/0002"

RTD1296_hwsetting_BOOT_4DDR4_4Gb_s1866.config

There are two files that you could modify with your hardware configuration for security.

project/target/rtd1295.mk

CHIP_ID ?= rtd1295

CUSTOMER_ID ?= demo

CHIP_TYPE ?= 0002

PRJ ?= 1296_force_emmc_S_E

NAS_ENABLE ?= 1

LK_FW_LOAD ?= 0

tools/flash_writer/inc/1296_force_emmc_S_E.inc

(Be selected with “project/target/rtd1295.mk”)

Board_HWSETTING = RTD1296_hwsetting_BOOT_4DDR4_4Gb_s1866.

Build bootcode

# ./build_rtk_lk.sh rtd1295

Output :

bootloader_lk.tar

2.2 Kernel

Cd Wrt/

Make menuconfig

2.3 Image file and Makefile.in

Copy the bootcode to ‘image_file’

#cp bootloader_lk.tar to ‘target/linux/rtd1295/image/image_file-r1005776/packages/omv’

Put the AES/RSA keys into ‘OpenWrt-ImageBuilder-rtd1295-nas_emmc.Linux-x86_64/target/linux/rtd1295/image/’

SDK 下载下来这个位置下有9把KEY 但不知道和bootcode 是否一致，所以手动再考一次

并且最好备份起来，以免后续换了Bootcode 什么的丢失

Copy these keys from Bootcode/tools/flash_write/image

(1) aes_128bit_key.bin

(2) aes_128bit_key_1.bin

(3) aes_128bit_key_2.bin

(4) aes_128bit_key_3.bin

(5) aes_128bit_seed.bin

(6) rsa_key_2048.fw.pem

(7) rsa_key_2048.tee.pem

(8) rsa_key_2048.pem

(9) rsa_key_2048.pem.bin.rev

To change the keys with your own, please follow the steps below.

Change the AES keys including

aes_128bit_key_1.bin

aes_128bit_key_2.bin

aes_128bit_key_3.bin

aes_128bit_key.bin

aes_128bit_seed.bin

Please use vi to modify these 5 AES keys directly. Be aware that each should be 16 bytes.

Steps: (Please progress in sequence, do not skip or reverse steps)

(1) Open binary file with vi

#vi -b aes_128bit_seed.bin

(2) Transfer to hexadecimal

: :%!xxd

0000000: 11cd ef12 1357 2468 a1b2 c3d4 9090 babe .....W$h........

0000010: 0a .

(3) Edit the content of AES bin file

(4) Transfer to binary

: :%!xxd -r

(5)Save and exit

:wq

Change the RSA keys including

rsa_key_2048.fw.pem

rsa_key_2048.pem

rsa_key_2048.tee.pem

These three RSA should use the instruction of 'openssl genrsa -out KEY' 2048' to generate.

For example, openssl genrsa -out rsa_key_2048.fw.pem 2048

Put the efuse utilities into ‘OpenWrt-ImageBuilder-rtd1295-nas_emmc.Linux-x86_64/target/linux/rtd1295/image/’

Copy it from tools/efuse_verify/out

(1) efuse_programmer.complete.enc

(2) efuse_verify.bin

Modify Makefile.in

#Vim OpenWrt-ImageBuilder-rtd1295-nas_emmc.Linux-x86_64/target/linux/rtd1295/image/ Makefile.in

注意：

制作加密包时，

用于MPTOOL 的生产包，secure_boot:=y，efuse_fw=1，efuse_key?=1，offline_gen=y，install_bootloader=1

之后用来USB 升级的以及制作OTA的包

secure_boot:=y，install_bootloader=1（这个根据需求决定是否打开）

# default value

# 1 = yes, 0 = no

install_bootloader=1

install_factory?=0

update_etc=1

stop_reboot=0

only_install_factory=0 # TODO: need confirm?

only_install_bootcode=0 # TODO: need confirm?

jffs2_nocleanmarker=0

install_dtb=1

# value

install_avfile_count=0

reboot_delay=5

customer_delay=0

rba_percentage=5

# 0: means use defalt;FAIL:1/INFO:2/LOG:4/DEBUG:8/WARNING:16/UI:32/TARLOG:256/MEMINFO:512

logger_level=0

layout_type=emmc

#layout_type=$(SUBTARGET)

layout_size:=$(if $(CONFIG_TARGET_LAYOUT_SIZE_8GB),8gb,4gb)

layout_size:=$(if $(CONFIG_TARGET_LAYOUT_SIZE_16GB),16gb,$(layout_size))

layout_size:=$(if $(CONFIG_TARGET_LAYOUT_SIZE_32GB),32gb,$(layout_size))

secure_boot:=y 直接写死不要有MAKEFILE 传参数

efuse_key?=1

chip_rev:=2 直接写死不要有MAKEFILE 传参数

hash_imgfile=1

verify=1

offline_gen=y

gen_install_binary?=n

ANDROID_IMGS?=n

HYPERVISOR=$(if $(CONFIG_XEN),y,n)

efuse_fw=1

处理bluecore.audio

将要使用的bluecore.audio ,zip起来放到这两个位置替换原有

OpenWrt-ImageBuilder-rtd1295-mnas_emmc.Linux-x86_64/target/linux/rtd1295/image/files

bluecore.audio.release_160705_81b00000.SQA.zip

OpenWrt-ImageBuilder-rtd1295-mnas_emmc.Linux-x86_64/target/linux/rtd1295/image/files/fw

bluecore.audio.zip

LK 烧录时，注意TOOL 要选择lk 打勾

3 Generate Image

3.1 Build install image

# cd OpenWrt-ImageBuilder-rtd1295-nas_emmc.Linux-x86_64

# make modules V=99 -j4; make image PACKAGES=ALL

Output:

OpenWrt-ImageBuilder-rtd1295-nas_emmc.Linux-x86_64/bin/rtd1295-glibc/install.img

3.2 Check install.img

Please check the components inside install.img, layout.txt and config.txt before doing installation, to avoid burning security failure. The files marked in red are only generated for security, and the files marked in blue are different from the normal installed package.
