# watchdog timer |
|||
|
|||
## 1. 例程介绍 |
|||
|
|||
本例程示范了baremetal环境中的看门狗功能使用。 |
|||
|
|||
本例程目前支持的demo包括使用中断喂狗和不使用中断喂狗两种。 |
|||
|
|||
## 2. 如何使用例程 |
|||
|
|||
|
|||
本例程需要用到 |
|||
- Phytium开发板（FT2000-4/D2000） |
|||
- [Phytium Standalone SDK](https://gitee.com/phytium_embedded/phytium-standalone-sdk) |
|||
|
|||
### 2.1 硬件配置方法 |
|||
|
|||
本例程支持的硬件平台包括 |
|||
|
|||
- FT2000-4 |
|||
- D2000 |
|||
|
|||
对应的配置项是， |
|||
|
|||
- CONFIG_TARGET_F2000_4 |
|||
- CONFIG_TARGET_D2000 |
|||
|
|||
### 2.2 SDK配置方法 |
|||
|
|||
本例程需要， |
|||
|
|||
- 使能FWDT |
|||
|
|||
对应的配置项是， |
|||
|
|||
- Use FWDT |
|||
|
|||
### 2.3 构建和下载 |
|||
|
|||
#### 2.3.1 构建过程 |
|||
|
|||
- 在host侧完成配置 |
|||
>配置成D2000，对于其它平台，使用对于的默认配置，如FT2000-4 `make config_ft2004_configs` |
|||
``` |
|||
$ make config_d2000_configs |
|||
$ make menuconfig |
|||
``` |
|||
|
|||
- 在host侧完成构建 |
|||
``` |
|||
$ make |
|||
``` |
|||
|
|||
#### 2.3.2 下载过程 |
|||
|
|||
- host侧设置重启host侧tftp服务器 |
|||
``` |
|||
sudo service tftpd-hpa restart |
|||
``` |
|||
|
|||
- 开发板侧使用bootelf命令跳转 |
|||
``` |
|||
setenv ipaddr 192.168.4.20 |
|||
setenv serverip 192.168.4.50 |
|||
setenv gatewayip 192.168.4.1 |
|||
tftpboot 0x90100000 baremetal.elf |
|||
bootelf -p 0x90100000 |
|||
``` |
|||
|
|||
### 2.4 输出与实验现象 |
|||
|
|||
- 启动进入wdt测试，分为定时器喂狗和不喂狗。 |
|||
|
|||
#### 2.4.1 启用定时器喂狗 |
|||
|
|||
- 配置看门狗定时器中断，设置6s喂狗一次。 |
|||
|
|||
 |
|||
|
|||
#### 2.4.2 不喂狗 |
|||
|
|||
- 不配置看门狗定时器中断，设置超时时间为6s，两次超时(12s)后系统复位。 |
|||
|
|||
 |
|||
|
|||
## 3. 如何解决问题 |
|||
|
|||
Q: 看门狗复位时间 |
|||
|
|||
A: FWdtSetTimeout设置的时间为看门狗定时器的超时时间，两次超时后系统复位。 |
|||
|
|||
## 4. 修改历史记录 |
|||
|
|||
v0.1.1 初次合入watchdog timer |
|||
