How can activate/enable UART3-Rx/Tx in i.MX6Q ?

jaymind — Tue, 10 Mar 2015 09:47:44 GMT

Hello,

I have i.MX6Q and I want to connect one extra peripheral on UART which name in i.MX6-Q processor is UART3-Rx and UART3-Tx.

So please suggest me that How can I enable it or add it or activate it or test it on my board ? :smileyconfused:

Is there any setting in menuconfig or u-boot ?

And How can I check that this particular UART is activated in my system ? :smileyconfused:

I already wire out pins Rx, Tx and GND form their locations.

So please give me solution that how can I test that UART3.?

I ran below command and checked on my PC on other UART port,

echo "test" > /dev/ttymxc3

but nothing happened. :smileysad:

So, give solution regarding to this.

Thanks and Regards

Jaymin D
