2、SDK的配置及系统镜像编译、生成

LinuxSDK准备好之后，接下来重点介绍一次性全部编译和部分编译的过程。编译完成后，可通过打包指令生成最终的img（该img文件可通过烧写工具烧写到开发板）。既然介绍编译，首先少不了编译用的指令，每个SDK的编译指令估计都有略微的差别，以下介绍全志T536的SDK中都支持哪些编译指令，通过如下指令进行查看：

Host#  source build/envsetup.sh

备注：进入LinuxSDK源码的根目录执行该命令。

执行source build/envsetup.sh指令后，信息中展示了相关指令，以下是对这些指令的介绍：

备注：

1）croot/ctarget等是快速切换目录的指令。例如：croot是直接切换到SDK根目录。其他指令用户可自行摸索。

2）通常不执行source build/envsetup.sh指令，这样的话，切换目录的快捷指令如croot/ctarget等等无法使用。另外执行表中指令时要加上./，例如：./build.sh menuconfig。

3）最快编译出固件的几条指令：

Host#  ./build.sh config

Host#  /build.sh

Host#  /build.sh pack

2.1、配置SDK生成配置文件

进入LinuxSDK源码目录执行如下命令，配置内核版本、处理器型号、评估板型号、显示方式、编译器等信息。

Host#  cd T536/T536_Tina5.0_AIOT_V1.1/

Host#  ./build.sh config

备注：

1. 首次执行上述命令会出现官方阅读说明，在等待倒计时结束后输入"Y"，按回车确认即可。
2. 如需配置Linux内核，Config配置选项"All available kern_name"请选择"linux-5.10- origin"；如需配置Linux-RT内核，Config配置选项"All available kern_name"请选择"linux-5.10-rt"。

embfly@embfly-virtual-machine:S cd T536/T536 Tina5.0 AIOT V1.1/

配置完成后，我们可以查看sdk的配置文件来判断配置是否正确，该配置文件是位于SDK根目录下的.buildconfig(只有通过ls -al指令才能看到该文件)。以我们刚刚生成的配置文件为例，.buildconfig内容如下：

export LICHEE_PLATFORM=linux

从以上信息可以获得LICHEE_BOARD=stk-t536，编译的固件是针对主板stk-t536，该主板的相关配置信息都保存在SDK根/device/config/chips/t536/configs/stk-t536目录，该目录中的内容如下：

embfly@embfly-virtual-machine: ~/T536/T536_Tina5.0_AIOT_V1.1$ cd device/config/chips/t536/configs/stk-t536
embfly@embfly-virtual-machine: ~/T536/T536_Tina5.0_AIOT_V1.1$ cd device/config/chips/t536/configs/stk-t536$ tree -L 1
.
├── arisc.config

├── sys_config.fex
├── uboot-2023
└── ubuntu

因本次选择编译buildroot，那么在stk-t536配置文件夹下的buildroot目录中就可以找到BoardConfig.mk文件，该文件确认了LICHEE_BR_DEFCONF（buildroot的默认配置文件）为sun55iw6p1_aiot_t536_defconfig，同时该文件还明确了编译内核时的配置文件为LICHEE_KERN_DEFCONF=buildroot_linux_defconfig，BoardConfig.mk内容如下：

LICHEE_BUILDING_SYSTEM:=buildroot
LICHEE_BR_VER:=202205
LICHEE_BR_DEFCONF:=sun55iw6p1_aiot_t536_defconfig
LICHEE_KERN_DEFCONF:=buildroot_linux_defconfig
LICHEE_NO_RAMDISK_NEEDED:=y

我们本次选择内核是linux-5.10-origin，那么在stk-t536配置文件夹下的linux-5.10-origin目录，我们可以找到buildroot_linux_defconfig。

├── board_stk_t536.dts
├── bsp_defconfig
└── buildroot_linux_defconfig

如果期望编译的固件内核是实时内核，那么在执行.build.sh config时，要选择linux-5.10-rt，那么在stk-t536配置文件夹下的linux-5.10-rt目录，我们可以找到实时内核的配置buildroot_linux_defconfig。

通过以上信息可以判断生成的.buildconfig文件是正确的。接下来即可进行固件的编译。

2.2、编译 LinuxSDK

2.2.1、配置内核选项

我司默认配置的是Linux内核（推荐使用），如对系统实时性要求较高，则需配置编

译Linux-RT内核。如需修改内核编译选项配置，请继续执行"./build.sh menuconfig"命令打开图形配置界面。此命令通过读取.buildconfig中LICHEE_KERN_DEFCONF指定的内核配置文件，以图形界面的方式提供内核编译配置查看和修改方法。如无需修改内核编译选项配置，可跳过此步骤。

menuconfig是一套图形化的配置工具，需要ncurses库支持。ncurses库提供了一系列的API函数供调用者生成基于文本的图形界面，因此需要先参考“安装依赖环境”章节安装ncurses库。ncurses库安装完成后，执行如下命令打开图形配置界面。

Host#  cd /home/embfly/T536/T536_Tina5.0_AIOT_V1.1/

Host#  ./build.sh menuconfig

embfly@embfly-virtual-machine: ~$ cd /home/embfly/T536/T536_Tina5.0_AIOT_V1.1/
embfly@embfly-virtual-machine:/T536/T536 Tina5.0 AIOT V1.1$ ./build.sh menuconfig

可通过键盘的方向键选中对应菜单栏。在<Select>被选中的情况下，可按Enter键进入子菜单。菜单选项中蓝色高亮的字母代表此菜单选项的快捷键，可在键盘上按下对应的字母快速选中对应的菜单选项。

每个菜单选项前的括号内容表示当前菜单选项的配置状态。选中对应的菜单选项后，按下Y键，会将相应的选项配置编译到内核中，同时菜单选项前面变为<*>。按下N键，不会将相应的选项配置编译到内核中。按下M键，会将相应的选项配置编译为内核模块，菜单选项前面变为<M>。如需搜索，可按下/键打开搜索框，然后输入要搜索的内容。

2.2.2、保存内核配置

内核配置完成后，可以进行编译并生效。如果要把当前的内核配置保留下来后续使用，务必执行如下命令，保存配置的选项。Linux内核配置保存在"device/config/chips/t536/co nfigs/stk-t536/linux-5.10-origin/buildroot_linux_defconfig"；Linux-RT内核配置保存在"device/config/chips/t536/configs/stk-t536/linux-5.10-rt/buildroot_linux_defconfig"。

Host#  ./build.sh saveconfig

embfly@embfly-virtual-machine: ~/T536/T536_Tina5.0_AIOT_V1.1$./build.sh saveconfig 
05-12 17:54:25.476 129924 D mkcommon: ========ACTION List: handle_defconfig saveconfig;=======

05-12 17:54:25.561 129924 D mkcommon: GEN Makefile
05-12 17:54:26.214 129924 D mkcommon: make[1]: Leaving directory '/home/embfly/T536/T536_Tina5.0 AIOT V1.1/out/t536/kernel/build'

embfly@embfly-virtual-machine:~/T536/T536_Tina5.0_AIOT_V1.1$

2.2.3、配置 Buildroot

如需修改 Buildroot 配置，请执行如下命令打开 Buildroot 配置界面，通过读取

"out/t536/stk-t536/buildroot/buildroot/"目录下的.config 文件，以图形界面的方式提供文件系统编译配置查看和修改。如无需修改 Buildroot 配置，可跳过此步骤。

Host# cd /home/embfly/T536/T536_Tina5.0_AIOT_V1.1/

Host# ./build.sh buildroot_menuconfig

可通过键盘的方向键选中对应菜单栏。在<Select>被选中的情况下，可按 Enter 键进入子菜单。菜单选项中蓝色高亮的字母代表此菜单选项的快捷键，可在键盘上按下对应的字母快速选中对应的菜单选项。

每个菜单选项前的括号内容表示当前菜单选项的配置状态。选中对应的菜单选项后，按下 Y 键，会将相应的选项配置编译到 Buildroot 中，同时菜单选项前面变为< * >。按下N 键，不会将相应的选项配置编译到 Buildroot 中。如需搜索，可按下/键打开搜索框，然后输入要搜索的内容。

配置完成后，选中<Save>，按Enter键保存配置选项。然后选中<Exit>，按 Enter 键退出。退出后，即可进行buildroot根文件系统的编译。

2.2.4、保存buildroot的配置

为了保留buildroot的配置下次使用，需要执行如下命令，保存buildroot配置选项。配置选项将自动保存至"/home/embfly/T536/T536_Tina5.0_AIOT_V1.1/buildroot

/buildroot-202205/configs/sun55iw6p1_t536_defconfig"。这个配置是在SDK的配置文件.buildconfig中指定。指令如下：

Host# ./build.sh buildroot_saveconfig

2.2.5、编译 LinuxSDK

在LinuxSDK源码目录下执行如下命令，一键编译SPL、U-Boot、Linux内核和Buildroot根文件系统。

Host#   ./build.sh

备注：若修改内核、Qt模块等配置，需重新执行"./build.sh"命令，再打包生成 Buildroot Linux系统镜像文件。

预计耗时约30min（时间取决编译主机的配置）编译完成后，生成 SPL、U-Boot、Linux内核和Buildroot文件系统镜像文件，镜像文件需转化为.fex格式后使用。

本次操作会将SPL镜像（boot0_nand_sun55iw6p1.bin、boot0_sdcard_sun55iw6p1.bin 和boot0_spinor_sun55iw6p1.bin）转化为boot0_sdcard.fex、boot0_nand.fex、boot0_spin or.fex文件；将U-Boot镜像(u-boot-sun55iw6p1.bin)、U-Boot设备树镜像、sys_config配置文件合并生成boot_package.fex文件；将内核镜像(boot.img)、内核设备树镜像转化为boot.fex文件；将文件系统镜像文件转化为rootfs.fex文件。

最后将boot0_sdcard.fex、boot0_nand.fex、boot0_spinor.fex、boot_package.fex、boot.fex、rootfs.fex等文件，打包生成"out/t536_linux_stk-t536_uart0.img"buildroot系统镜像文件。
