freeRTOS_UART example faults in UART_RTOS_Send

MCUXpresso IDE v11.0.0 [Build 2516] [2019-06-05]

Device: MKL26Z256xxx4

SDK_2.x_MKL26Z256xxx4 2.4.1


I started with the freeRTOS_UART example project.

I had to change the MCU and package.

See attached project 


My custom board has a MKL26Z256 that is connected to a modem at 115200.


In fsl_uart_freertos.c, UART_RTOS_Send() calls UART_TransferSendNonBlocking().

The problem is that UART_RTOS_Send()'s 2nd parameters is not a uart_handle_t *.

This causes a fault when UART_TransferSendNonBlocking() attempts to deference the bad pointer.


Call stack:

Thread #2 536867576 (Uart_task : Running [P: 4]) (Suspended : Breakpoint) 
UART_TransferSendNonBlocking() at fsl_uart.c:734 0x18a0 
UART_RTOS_Send() at fsl_uart_freertos.c:229 0x6e8e 
uart_task() at freertos_uart.c:133 0x5ec 
pxPortInitialiseStack() at port.c:102 0x2dfc


The amazon-freertos code appears to be out of sync with the generated drivers files.


Does anyone have a suggestion that will correct this?
