IMX28 UART0 test

alexaldridge — Wed, 23 Mar 2016 11:26:46 GMT

Hi mates! I've successfully booted into linux Kernel and installed Java. Now I'm looking for a way for testing UART0. I had thought about doing an echo like this:

echo "hello" > /dev/tty0 but does not seem to work.

Could you please point me the right direction?

Hello,

The Debug UART can be accessed through the /dev/ttyAM0 device file.

The application UART can be accessed through the /dev/ttySP0 device file.

Regards,

Yuri.
