Configuring MKL25 LPSCI with fsl_lpsci Processor Expert bean

I'm developing a project with MKL25Z128 and I'm making some tests with LPSCI, using "fsl_lpsci" Processor Expert bean, but I have run into some problems:


I created a simple routine: I receive a character typed on a Windows Terminal like Tera Term, for example, and send back (echo) to the Terminal.


When the rx_buffer full Callback function is enabled, as well as the ISR Handler, I don't receive any data typed from Terminal. I put a breakpoint inside ISR_Handler after SCI Receiver Buffer Full flag checking line, but it doesn't stop there. When Rx_Callback function and ISR Handler are disabled, it works perfectly.


I don't know if I did something wrong. I have spent many hours of attempts strugling on that.


I hope someone has faced the problem as mine and can help me with that.


I attach my simple code for better visualization.



Thanks and best regards,


Marco Coelho
