RT1015 LPUART_TransferReceiveNonBlocking Driver

I am study UART with "evkmimxrt1015_lpuart_interrupt_rb_transfer" SDK sample code.


The sample code is no problem.

After I modify some flow, it cannot receive any byte, 

My idea is using polling to call LPUART_TransferReceiveNonBlocking, if get any byte, use tx send a debug log.

I don't know why this modification cannot receive any RX byte.


Maybe there are some constrain to using LPUART_TransferReceiveNonBlocking?

I attached the source code. I only modify this file.


Can someone give me a hint?
