器件型号：AM62P 主题中讨论的其他器件：SysConfig、 TPS65224-Q1
工具与软件：
我要使用的 SDK 是 mcu_plus_sdk_am62px_10_00_00_14
我们使用的是一个定制电路板、其中我们连接了2个 I2C、一个是 MCU_I2C0、另一个是 WKUP_I2C0。
请参阅下图以供参考：
我使用的示例是 "PMIC_QA_WATCHDOG_RESET"。
我已修改 PMICApp_wdogQAModeReset。

编译并运行代码后、我将得到以下输出。
正在启动 Q&A 看门狗复位示例！！
根据通信模式为 Q&A 看门狗配置 PMIC GPIO 引脚... 停止更新的
看门狗禁用成功！！
在 Q&A 模式下配置 PMIC 看门狗... 停止更新的
错误：PMICApp_wdogQAmodeReset：337：PMIC Q&A 看门狗复位模式测试... 失败！！
错误：PMIC_QA_WATCHDOG_RESET_MAIN：143：某些测试失败！
没有手表被禁用并且 MCU 在一段时间后被复位。
您能帮助解决这个问题吗？
