I am suffering a problem, how to add a new UART in iMX6 solox platform?
I have looked thought some of relevant papers, such as “BSP porting guide”, “Linux user guide”, “datasheet of iMX6” etc.. I saw that there are two default UARTs, which are used for debugging A9 and M4 cortex in the demo Yocto project in default. I am still confusing how to set a new UART (such as UART3/4/5) in the demo board. To be fair, the new UART will be used to connect an extra sensor (Ultrasonic sensor), which is RS-232 communication protocol between the iMX6’s board and it.
Could anyone can tell me how to do that? Many thanks.
