Hi
On fsl-yocto-4.1.15_1.1.0
We found that uart driver of fsl-yocto-4.1.15_1.1.0 support RS-485,and we used ioctl to use RS-485 to receive and send data to another device,but it only can receive the first data ,the second time we want to re-transmit and get no response
I print USR2 register ,the first time I receice data the USR2 is 4008,the second time I receive date the USR2 is 5008
According to imx6 DRM ,it means IDLE condition has been detected.
Please help to solve this issue
Thanks
