Raspberry 0 and on board uart

[mrdebug]

Hi, I can't use the uart of my new raspberry 0 wireless.
If I insert the system sd in a raspberry 3, the uart works and I can use it.
What do you think about? Is my raspberry damaged?

Did you enable uart in 'rasp-config'?
How are you trying to address it (please post any commands/code)

Solved by using ttyS0 instead of ttyAMA0

[bensimmo]

ZeroW and Pi3's both use ttyS0 for the gpio UART
(Anything with WiFI/BT onboard)

Zero and Pi2/Pi's use ttyAMA0 for gpio UART.

To make it cross compatible use
/dev/serial0
It directs to the gpio UART no matter which Pi.
