iMX8QM开发板回环测试lpuart

[EmptyObject_]

使用iMX8QM开发板回环测试lpuart，发送一次数据，但是lpuart接收那边会收到三次数据，测了好几个lpuart都是这样，是因为内核中的驱动文件fsl_lpuart.c里面的问题嘛，我用的是Android AutoMotive13.0.0_1.1.0

Hi @EmptyObject_ 

I hope you are doing well

Have you modified the driver file fsl_lpuart.c?

Please share your connection in case of loopback mode to further debug the issue.

Thanks & Regards
