# 安全启动与升级
本工程中于示例[安全启动](https://docs.bekencorp.com/armino/bk7236/zh_CN/latest/developer-guide/security/bk_security_boot.html)，[安全升级](https://docs.bekencorp.com/armino/bk7236/zh_CN/latest/developer-guide/ota/bk_security_ota.html)。
**BK7236 安全功能还在开发与完善中，请注意下述限制**
- 本工程仅支持在 8M FLASH 上运行。
- 构建生成的 otp_efuse_config.json 仅使能安全启动及 FLASH AES 加密功能，您可通过 EFUSE 使能更多安全特性。
- 示例日志中，BL1/BL2 以及安全世界（TF-M）开启了部分日志，您可选择通过 EFUSE 或者编译选项关闭。
## 如何使用工程
### 硬件要求
8MB FLASH 的 BK7236 开发板。
### 编译
#### 编译命令
在 Armino 根目录下输入下述命令进行编译：
> make bk7236 PROJECT=security/secureboot APP_VERSION="v1.0"
工具链安装等准备工作请参考[快速入门](https://docs.bekencorp.com/armino/bk7236/zh_CN/latest/get-started/index.html)。
#### 生成不同版本号
如果您想运行安全升级，建议使用不同的 APP_VERSION 编译两次，例如：
- 首次编译时，APP_VERSION="v1.0"，生成的 all-app.bin 用于烧录。
- 第二次编译时，APP_VERSION="v2.0"，生成的 ota.bin 用于升级。
通过检查启动日志中 APP Version 就可以判断当前运行的版本。也可通过打印时间判断使用的版本:
```
bk_init:I(0):armino app init: Jul 21 2023 10:12:47
bk_init:I(2):APP Version: v1.0
```
#### 配置安全计数器
可通过工程下的 ota.csv 中的 app_security_counter 来配置安全计数器，它用于防止升级时版本降级。
要注意 ota.csv 中 app_security_counter 不能小于 BK7236 开发板上当前运行程序的 app_security_counter 值，
否则无法升级成功。如果开发版本上从未运行过安全启动程序，则 app_security_counter 值应该为 0。
关于 app_security_counter 可参考 [安全配置](https://docs.bekencorp.com/armino/bk7236/zh_CN/latest/developer-guide/config_tools/bk_config_security.html)
#### 配置 BL2 日志级别
可通过工程下 config/bk7236/config 修改 CONFIG_TFM_BL2_LOG_LEVEL 来配置 BL2 日志级别。
### 连接 UART
UART0 用于 BKFIL 进行烧录，非安全世界的日志显示以及以及 CLI 命令输入。
UART1 用于安全世界的日志显示。
### 烧录 all-app.bin
将 Armino/build/secureboot/bk7236/all-app.bin 使用 BKFIL 烧录到板子上。
### 配置 OTP/EFUSE
将 Armino/build/secureboot/bk7236/otp_efuse_config.json 文件烧录到开发板上，烧录步骤请参考[OTP/EFUSE 配置](https://docs.bekencorp.com/armino/bk7236/zh_CN/latest/developer-guide/config_tools/bk_config_otp_efuse.html)。
**重要：请先烧录 all-app.bin，再配置 OTP/EFUSE，配置过程中避免断电**

## 安全启动
### 安全启动 CLI 命令
配置完 OTP/EFUSE 之后，重启开发板即可观察到安全启动流程。

## 安全升级
在安全启动的基础上可以进一步示例安全升级，包括下述几步：
- 启动 HTTP 服务器
- 连接路由器
- 触发升级
### 启动 HTTP 服务器
使用 HFS(Http File Server) 来启动一个 HTTP 服务器，您也可以使用其他 HTTP 服务器。
将 Armino/build/secureboot/bk7236/ota.bin 拷到 HFS 服务器上，如下图所示:
![HFS 服务器](hfs.png)
### 连接路由器
测试安全升级时，运行 HTTP 服务器的电脑与开发板需要处于同一局网中。
本例路由器/密码为 Tenda_062C88/1234568，使用下述命令将开发板连接到路由器上:
> sta Tenda_062C88 12345678
### 触发 OTA
使用下述命令运行 OTA:
> http_ota http://192.168.5.100:8080/ota.bin
### 重启
当 OTA 下载完成且 TF-M 对下载的 IMAGE 完整性检查完成之后，手动重启板子，重启后 BL2 对下载的 IMAGE 验签，验签通过了
之后将 IMAGE 搬到主分区。

#### 重启后安全世界日志
下载完成后，重启开发板，BL2 会对下载的 IMAGE 进行验签，验签通过之后交换到主分区，可以观察到 BL2 会打出 Swap type: test 与
Starting swap using move algorithm，表示使用
完整日志如下:
```
