器件型号:AM620-Q1

工具与软件:

您好、亲爱的专家

环境、

SDK 10.0

HW、AM62_LP_EVM 和 AM62A_LP_EVM

按照该指令进入深度睡眠模式。

https://software-dl.ti.com/processor-sdk-linux/esd/AM62AX/10_00_00/exports/docs/linux/Foundational_Components / Power_Management / Pm_low_power_modes.html?highlight=sleep%20mode

echo mem > /sys/power/state

我们的转储消息如下所示、

但我认为标准消息如下。

echo mem > /sys/power/state

似乎我们丢失了一些日志消息、 深度睡眠是否正常?

或者我会错过什么吗?

非常感谢
