LPSCI - how does it function on FRDM-KL25Z

Hi,

 

As per what i have noticed from FRDM-KL25Z_SCH_REV_E shematics UART0_RX/TX of KL25Z is connected to UART1RX/TX of K20 i.e. the OpenSDA Debugger in this case.

 

Lets consider the following case:

1. Ive designed a standalone KL25Z board without any debugger but only with header for debugging/programming and other GPIOs

2. Debugged/Programmed using K20 available on FRDM-KL25Z

 

Problem:

If i were to use the LPSCI polling example for frdm-kl25z would it work for my standalone KL25z board, if "yes" how would its interface be designed to the USB port.

 

 

Regards,

Nelson
