FRDM-KL46Z FreeRTOS example UART and SPI Project Issues

Contributor I

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.
