Hi @Turtledove,

From your other community post, I assume you are using S32DS for ARM with the SDK, is this correct?

You can find the example descriptions under your S32DS installation (C:/NXP/S32DS_ARMv2.2/S32DS/software/S32SDK_S32K1xx_RTM_3.0.0/doc/html_S32K148/flexio_uart_s32k148_group.html).

The example uses two instances of the FlexIO UART driver are used to echo the data received from host. Here are the connections and steps to run:

The example configures the terminal with these settings:

115200 baud
One stop bit
No parity
No flow control

Lastly, as I've mentioned in your other post, for Real-Time Expressions, please refer to this thread: Solved: How do I enable Live View for variables when debugging? - NXP Community.

Best regards,
Julián
