器件型号： AM62A7

您好、  

最近、VTM（热管理器框架）用于我们的电路板 AM62A7。 在过热 VTM 上调用 ordered_poweroff (true) 函数。 它可以清理应用层、但不会复位以太网、GPIO、PWM 等接口 这是 ORDERDY_poweroff () 的已知行为还是应该重置所有的负面?

    您好、Jay、

    您可以在执行断电时共享日志吗？

    应该会暂停 Linux 驱动程序、但我需要检查是否执行了任何其他步骤。

    此致、

    我可以看到、驱动器没有像以前那样被移除/挂起、因为以太网指示 LED 和 PWM LED 亮起。 此外、摄像头传感器的电源仍处于开启状态、并由 GPIO 控制。 如果.remove 功能执行正常、摄像机电源应关闭。

    如果我方面还需要其他任何东西、请允许我这样做。

    此致、

    Jay

    尊敬的 Jay：

    一个后续问题：

    不会重置以太网、GPIO、PWM 等接口

    您能解释一下期望它做什么吗？ 您是否希望这些外设完全关闭？ 这些 IO 的 PMIC 电源轨是否发生了变化？

    此致、
