Question
rpici
I am using your Debian (wheezy) on a SolidRun Hummingboard-i2eX.
uname -a
Linux cubox-i 3.14.14-cubox-i #2 SMP Mon Aug 31 19:36:11 CDT 2015 armv7l GNU/Linux
In /dev, it looks like there are two IMX serial devices:
ls -l /dev/ttymxc*
crw-rw---T 1 root dialout 207, 16 Feb 4 2001 /dev/ttymxc0
crw-rw---T 1 root dialout 207, 19 Feb 4 2001 /dev/ttymxc3
I can send/receive data from /dev/ttymxc0 (uart1) by using pin 8 (Tx) and pin 10 (Rx) of the 26-pin header on the board.
But how can I access /dev/ttymxc3 (uart4)? Is there a pin somewhere on the board that I can connect to so I that I can send serial input to uart4?
Thank you.
