hi,
I am using imx6q sabreauto board, till yesterday uart was working fine, but now it's not, is there any other option to get uart output???.
Hi Dan,
uart cable is working fine for other board. but only when i plug it to one particular device it's giving some junk value, is there any other way so that i can uart output??
what i need to change serial.h???
Here is code which is there
/* UART 1 configuration */
/*!
* This specifies the threshold at which the CTS pin is deasserted by the
* RXFIFO. Set this value in Decimal to anything from 0 to 32 for
* hardware-driven hardware flow control. Read the HW spec while specifying
* this value. When using interrupt-driven software controlled hardware
* flow control set this option to -1.
