Other limitations

  • Documentation may not be fully updated to refer to KW47 devices.

  • GenFSK Connectivity_test application is not operational with ARMGCC compiler.

  • GenFSK Connectivity_test application is not operational with Low Power enabled.

  • Serial manager is only supported on UART (not I2C nor SPI).

  • The --no-warn-rwx-segments cannot been recognized on legacy MCUXpresso IDE versions.

    The --no-warn-rwx-segments option in MCUXpresso projects should be manually removed from the project settings if someone needs to use legacy (< 11.8.0) MCUXpresso IDE versions

  • If the FRO32K is configured as the clock source of Core 0 then the debug session will stuck in both IAR, MCUX CMSIS-DAP while debugging. Use a lower debug wire speed, for example 1 MHz instead of the default one.

    In IAR, the option is in Runtime Checking -> Debugger -> CMSIS DAP -> Interface -> Interface speed.

    In MCUXpresso IDE, the option is in LinkServer Debugger -> Advanced Settings -> Wirespeed (Hz).

  • If the configuration tool is used to clone tfm-related projects, there is a problem that region_defs.h cannot be found in the cloned project.

  • Not supported features:

    • Platform low power modes not fully enabled in this release.

    • FRO32K mode not fully supported in this release.

  • Low power reference design applications are not supported for the armgcc toolchain from zip archives. Please use MCUXpresso IDE or IAR toolchains for development using these applications.

  • Some connection events may be missed by the NBU core firmware when an asynchronous wake up is triggered from the application core.
