I am using a MKM34Z256 - with Kinetis Design Studio and SDK V2 enviroment and FreeRTOS.

If I use the PRINTF Function, it looks like this funktion use the "UART_WriteBlocking" Function and so it blockes the rest of the system while giving out the UART-Data.


In fsl_debug_console.c in row 244 (approx) is the command:


 s_debugConsole.ops.tx_union.UART_PutChar = UART_WriteBlocking;


How can I change this to use the non blocking transfer function?

Thank You!

With best Regards
