Hi Community,

 

I am using Sabre-AI board running Android M with kernel 3.14.52.

I am trying to interface a GPS device with Android. I am using UART as the communication interface. As soon as the board boots I am getting the following error:

 

imx-uart 21e8000.serial: Rx FIFO overrun

imx-uart 21e8000.serial: Rx FIFO overrun

imx-uart 21e8000.serial: Rx FIFO overrun

imx-uart 21e8000.serial: Rx FIFO overrun

imx-uart 21e8000.serial: Rx FIFO overrun

imx-uart 21e8000.serial: Rx FIFO overrun

imx-uart 21e8000.serial: Rx FIFO overrun

imx-uart 21e8000.serial: Rx FIFO overrun

 

And the board hangs for sometime. The GPS HAL is not able to communication over UART.

I saw the thread  iMX6Quad uart RX Fifo Overrun  but it did not helped me.

Can anyone give me the solution

 

Thanks

Deepika
