Hi,
I have OlinuXino MICRO and I want to use other serial ports (UARTs) I see on CON2 there are AUART1_TXD/RXD (pins 5 and 6) and PWM0_DUART_RXD/TXD (pins 13 and 14). How can I access them? Are they linked to some tty?
Thanks,
Ivan

Hi,
I think it's the /dev/ttySP1 device.
Is there an example here :
https://github.com/OLIMEX/OLINUXINO/blob/master/SOFTWARE/iMX233/MOD-ZIGBEE/main.c (https://github.com/OLIMEX/OLINUXINO/blob/master/SOFTWARE/iMX233/MOD-ZIGBEE/main.c)
I'm also interested but don't have the time to test it for the moment.
Please, let us know if you can control this UART.

Laurent
Hi,
Yes, I managed to control it and it is /dev/ttySP1.
I have 2 MICROs and I connect them to each-other. On both I have installed minicom (pacman -S minicom) and they are talking to each other successfully.
I'm using this to control XBee Pro and to enter in command mode. And it works ;-)
Greetings,
Ivan
Thanks a lot for your feedback ;)

Hi Ivan,
Which Linux kernel version did you use and did you do something special?
I like to use the UART as well but fail to get a connection. Also in /dev/tty* I do not see the port.
Regards Rob.
Hi Rob,
the version I'm using is: 2.6.35-8-ARCH+ from the link below:

Hi froggysoft,
did You find linked tty for additional uart AUART1_TXD/RXD (pins 5 and 6) on OlinuXino MICRO?
I can't find ttySP1 (ls /dev/tty*) like You ...
Thank you
It's /dev/ttyAPP0 on latest kernels (3.7.9+). Comes from "application uart".
