Which products are you using?
IMX6U6AVM08AC(IMX6DL DDR_2G EMMC_4G)
kernel version:3.14.52
Uboot version:u-boot-2016.03
when I used the cmd "cat /dev/ttymxc3" at upper status,I found that the terminal printf "rx fifo overrun".However, the data transmission interval is 100ms, and each frame of data transmission is less than 20ms.In this case, what state is it that the register cannot be set?
tks
