现在我们项目gps模块使能由mcu控制,imx6在uart初始化之前就一直在收到gps数据

内核启动过程中不断打印如下log,不知道是什么原因导致的?

imx-uart 21ec000.serial: overwrite!

imx-uart 21ec000.serial: overwrite!

imx-uart 21ec000.serial: Rx FIFO overrun

which i.mx6 are you using? which BSP and board are you using?

is the GPS turned off when the kernel is starting? is there any GPIO to control the GPS?

我们用的是imx6d-sabresd ,bsp用的linux3.10.53+android4.4.3

gps 使能是由mcu控制;所以当内核启动的时候 gps是打开的。
