I have question about difference of Serial class on mbed using with between FRDM-K64F and LPC1768.

I make Tx and Rx(p9 and p10) shorted, and I run the program on LPC1768, I get recieved character.

However, PTC17 and PTC16 are short circuit, and comment out L6 and uncomment l7, then I run program on FRDM-K64F, I cant recieve any character.

I can recieve character on FRDM if I send only one character.

I can recieve all characters on LPC if I send 10 characters.

What is the difference.

Can you tell me how to get characters on FRDM-K64F?
