FRDM-KL46Z FreeRTOS example UART and SPI Project Issues

Hello everyone,

So, this is my first time using an ARM board, so I know so little. I have a FreeRTOS university project that utilises UART and SPI, so I was instructed to load the example SDK projects to familiarise myself. However, I've stumbled into some issues trying to run them.

For the freertos_uart project, I use Tera Term as my terminal and I adjust the serial port settings as the project suggests. I believe I've done so correctly:

From what I can see, the project should sent some text to the terminal, but it doesn't seem to work in my case; the window remains blank. Do I need to adjust some extra project/Tera Term properties for it to work?

As for freertos_spi project, I run the project, which sends some data and then receives it. I get multiple mismatch errors when data is received:

How could I get these projects to work? Maybe I should also note that I run MCUXpresso in a virtual machine with Windows 7 because running directly on Windows 10 had caused my board's bootloader to become corrupted.

Hi Konstantinos:

You can refer to the readme txt file under the demo folder.

for instance, For freertos uart project,

Hardware requirements
=====================
- Mini USB cable
- FRDM-KL46Z board
- Personal Computer
- USB to Com Converter

Board settings
==============
USB2COM UART1
Pin Name Pin Name Board Location
RX PTE0 J2 pin 18
TX PTE1 J2 pin 20
GND GND J2 pin 14

could you please check your board settings ?

Regards

Daniel
