- 2.cpu_wtd_sysfs：
- switchboard.c （fpga下i2c访问Switch CPLD1，Switch CPLD2 ：CPLD, FPGA , QSFP）
- script
- bmc_wtd：syscpld.c中wd_en和wd_kick节点对应寄存器，crontab，FUNCNAME
- AST2500/2600 WDT切换主备：BMC用WDT2作为主备切换的watchdog控制器
- AC后读取：bmc处于主primary flash（设完后：实际主，wtd1主，wtd2主）
- 切换spi备：wtd2的2c寄存器设为0x93，换另一个flash后reboot后从备起（设完后：实际备，wtd1主，wtd2备）
- 用WDT1切主：（设完后：实际备，wtd1备，wtd2备）
- 用WDT2切主：（设完后：实际备，wtd1备，wtd2主）
- 用WDT1切主：（设完后：实际主，wtd1主，wtd2主）
- 关于清空寄存器：（设完后：WTD1主，WTD2主，实际主）
- 结论：从主切到备，需要一个wdt的status是default也就是0的wdt，然后用0x93切换
- BMC喂狗实现：sys/class/gpio/gpio1/value获取gpio1值

AST2500/2600 WDT切换主备：BMC用WDT2作为主备切换的watchdog控制器
AC后读取：bmc处于主primary flash（设完后：实际主，wtd1主，wtd2主）
如下0x100代表default flash。
切换spi备：wtd2的2c寄存器设为0x93，换另一个flash后reboot后从备起（设完后：实际备，wtd1主，wtd2备）
如下202第1位（不是第0位）和第9位置为1，发现这时确实WDT2可控，当前在备flash启动。
用WDT1切主：（设完后：实际备，wtd1备，wtd2备）
用WDT2切主：（设完后：实际备，wtd1备，wtd2主）
用WDT1切主：（设完后：实际主，wtd1主，wtd2主）
关于清空寄存器：（设完后：WTD1主，WTD2主，实际主）
wdt1和wdt2都切到备flash。
如下clear寄存器清除wdt1的status，保留了reset次数，但是将code source（主备）清除为0（主）。
再用wdt2切换主。
这次切到了主。
用wdt1切换到备。
清空wdt1的status。这时如果用我们的测试脚本bootsource会判断是在主，其实是在备。
尝试wdt1用0x13切换主，成功切到主。
结论：从主切到备，需要一个wdt的status是default也就是0的wdt，然后用0x93切换
从备切到主，需要满足两（三）个wdt中都从备切到主。比如wdt1是备，wdt2是备，那要对wdt1，wdt2都下一次0x93。如果wdt1，wdt2中一个是备，那对对应的wdt下0x93。
还有因为清空寄存器造成的虽然在备，但是wdt都是显示在主，这时候用0x13就可以切到主。用wdt2进行切换主备。避免使用清空寄存器0x14/0x34。

BMC喂狗实现：sys/class/gpio/gpio1/value获取gpio1值
bmc喂狗gpio硬件管脚：
bmc监听gpio中断硬件管脚：
导出GPIO:echo $gpio_num > /sys/class/gpio/exporteg: echo 1 > /sys/class/gpio/export执行完以上命令后，如果该gpio接口存在且未被占用则会出现如下目录：/sys/class/gpio/gpio1设置方向:gpio的方向分为两类：in和outin:表示该gpio用于输入。（如该gpio连接一个按钮）out:表示该gpio用于输出。（如该gpio连接一个led灯）指定为in模式的命令：echo in > /sys/class/gpio/gpio1/direction指定为out模式的命令如下：echo out > /sys/class/gpio/gpio1/direction //默认value为0echo low > /sys/class/gpio/gpio1/direction //指定方向为out且value为0echo high > /sys/class/gpio/gpio1/direction //指定方向为out且value为1设置高低:只用当方向为out模式时才能指定gpio接口的电压的高低。这个很容易理解，因为如果是in模式的话，它的电平高低取决于所连接外设的电平高低，我们只能读取它的值，不能更改它的值echo 1 > /sys/class/gpio/gpio1/value //指定gpio1为高电平echo 0 > /sys/class/gpio/gpio1/value //指定gpio1为低电平
