器件型号:TAS2780

从错误日志来看、问题似乎是 i2c。但是、i2c 下面的其它外设可以正常通信

    您好!

    请确保硬件连接正常。 然后使用以下命令:

    i2cdump -y -f 0 0x38
    0 is i2c bus no
    0x38 is 7-bit i2c device address

    One more thing, what the 7-bit i2c address on your device? It seemed 0x70, this address is so strange,
    kindly check the datasheet and hardware engineer.
