Hi

I'm using the serial on p9 and p10, by changing the Serial Hello World code from USB. The output is just garbage. Seyon settings are 9600 8-N-1.

The output is 

o5''!�Q!
The code is

#include "mbed.h"              

Serial uart(p9,p10); // tx, rx

int main() {
    uart.printf("Hello World!\n");
}
Can anyone help? This is repeatable in cat and screen.
