Other Parts Discussed in Thread: AM3517

大家好,我在使用AM3517的过程中,发现机器突然死机了,终端显示如下信息,不停的打印,不知道为什么,请问一下,有什么方法可以解决这个问题,我用的是TI官方提供的DEMO包。

  • 请您明确下一下问题:

    1. 您所使用的开发部是否是ti原厂提供的开发板,是哪一款?

    2. 您所使用的demo sdk是哪个版本?

    3. 在什么情况下导致死机?

  • slave addr=0x4B这个设备连在哪个i2c上?比如连在nr上

    请在bootargs中加入i2c_bus=nr ,100

    降低i2c总线速度试试.
