UART problem with FRDMKL03 (with KDSK + PE + FreeRTOS)

I am trying to setup an environment under KDS with the new FRDMKL03. For that, I use Processor Expert to setup everything.


My goal is simple : output the stout to uart (which runs fine with demos provided).


I have tried it in 2 ways.


1/ Use Hal UART directly


But It hungs up on LPUART_HAL_IsTxDataRegEmpty (always false).

2 / Use fsl_debug_console.


But it does not solve my issue, and hangs up on Reserved 45_IRQHandler(). ( issue occurs even if I printf first or wait for task creation)

How do I correct this ? Do i have to import a specific .c in my path to handle this or correct my setup in PE ?

Thanks in advance,


P.S : My project uses FreeRTOS and KSDK.
