GETCHAR or SCANF UART For FRDM Board

micheal_saleab — Mon, 18 May 2020 12:07:37 GMT

I am using frdmk64f_agm04_sensorfusion_freertos_agm04 SDK, and I want to read via UART I can't read from UART.

I got an error after flashing the SW whenever I call GETCHAR or SCANF.

and debugging session close automatically

This is the error I get:
15: Target error from Set break/watch
Unable to set an execution break - no resource available.
Debugging context: frdmk64f_agm04_sensorfusion_freertos_agm04 LinkServer Debug

Could you support in this

Hi Michael, I hope you're doing well!

The debug console implemented for SDK examples in the MCUXpresso IDE can be changed in the following ways:

When importing an SDK example, select the Debug Console as UART instead of Semihost:

On an already created or imported project, you can change the project's quick settings to set the debug console to UART:

Please let me know if you need any more information.

Take care, best regards,

Sebastian

Hi Sebastian,

I changed the Debug console to UART console, and I am still getting the same error when I use SCANF.

Thanks,

Micheal

Hi Michael,

Could you please take a look at this page of the MCUXpresso SDK API Reference Manual and confirm that the debug console is being initialized and enabled successfully?

MCUXpresso SDK API Reference Manual: Debug Console

It also has some typical uses cases and examples for the GETCHAR and SCANF functions, could you please take a look at them?

Please let me know if you continue to have issues with this.

Take care, best regards,

Sebastian
