Development Tools 2 MCUXpresso SDK CMSIS packs introduction MCUXpresso SDK is delivered in Device Family Packs and Board Support Packs. 2.1 MCUXpresso SDK Device Family Packs Device Family Pack provides minimal device support. Installing DFP provides enough resources to create, compile and debug MCUXpresso SDK project. MCUXpresso SDK Device Family Pack contains: Device header files and system initialization modules Startup files Linker files SVD files Flash drivers (for some of the development tools) SDK drivers and utilities SDK project templates Content of the Device Family Pack is organized in following CMSIS components: Startup, contains minimal set of sources needed to create and compile MCUXpresso SDK project SDK drivers SDK utilities SDK CMSIS drivers RTE Device SDK project template, contains RTE_Device.h file required by CMSIS drivers Board SDK project template, contains board, clock configuration, peripherals and pin mux SDK configuration files with general implementation 2.2 MCUXpresso SDK Board Support Packs Board Support Pack provides support for NXP evaluation board and example projects for the board. MCUXpresso SDK Board Support Pack contains: Example projects and demo applications SDK project templates containing board, clock configuration, peripherals, and pin mux SDK configuration files implemented for the specific board. 3 Development Tools The MCUXpresso SDK CMSIS packs were compiled and tested with these development tools: MDK-Arm Microcontroller Development Kit (Keil) 5.23 IAR Embedded Workbench for Arm version 8.11.3 The MCUXpresso SDK CMSIS packs were compiled and tested using Arm::CMSIS pack version 5.1.0. 2 NXP Semiconductors

Workaround: Remove lines 588-599 from arm_math.h. 5.2 Not possible to download projects to board in IAR Embedded Workbench for Arm using CMSIS DAP default settings The MCUXpresso SDK projects created in IAR Embedded Workbench for Arm cannot be downloaded to the board using the CMSIS DAP debugger default settings. Workaround: Go to Project > Options > Debugger > Download, enable Override default.board file and select appropriate.board file from {Embedded Workbench installation NXP Semiconductors 7

Known Issues directory}\arm\config\flashloader\nxp\. Additionally, in Debugger > CMSIS DAP > Reset set the reset source to Software. Figure 1. Overriding default flash loader in IAR Embedded Workbench for Arm Figure 2. Setting CMSIS DAP software reset in IAR Embedded Workbench for Arm Alternatively, switch the processor from CMSIS-Pack variant to Device variant in Project > Options > General Options > Processor variant. 8 NXP Semiconductors

5.3 Not possible to debug K64 and K65 projects in IAR Embedded Workbench for Arm using P&E micro Known Issues In case of FRDM-K64F, TWR-K64F120M, and TWR-K65F180M boards, MCUXpresso SDK projects created in IAR Embedded Workbench for Arm cannot be debugged using P&E micro debugger. Workaround: Switch the processor from CMSIS-Pack variant to Device variant in Project > Options > General Options > Processor variant. 5.4 Warnings about too many memory zones reported in IAR Embedded Workbench for Arm For some devices, a warning about too many memory zones is reported for device description files (*.ddf) generated into Device Family Packs directory by IAR Embedded Workbench for Arm. Figure 3. Warning about too many memory zones defined in device description file When downloading application to board using CMSIS DAP debugger, the following warnings can also be shown followed by list of registers: Some SFRs are placed outside known memory areas, or in memory areas designated as read-only or as RAM Workaround: Go to Project > Options > Debugger > Setup > Device description file, enable Override default and select appropriate *.ddf file from {Embedded Workbench installation directory}\arm\config\debugger\nxp\.

Workaround: Use Project > Create New Project > CMSIS Pack example in IAR Embedded Workbench for Arm to create new projects from example projects in BSPs. 5.6 Not possible to compile new projects created for LPC devices in IAR Embedded Workbench for Arm because of missing Power driver library. New projects created in IAR Embedded Workbench for Arm for LPC devices that uses Power driver library component (Device > SDK Drivers > powerlib) may not compile due to limitation in the development environment causing that path to the library file is not set in the project linker settings. 10 NXP Semiconductors

Known Issues Figure 5. Power driver library component Workaround: Add path to the power library file as additional library in Project > Options > Linker > Library > Additional libraries. The Power library file can be found in {Embedded Workbench PackRepo directory}\nxp\{device Family Pack}\{version}\iar\iar_lib_power.a. To find the Embedded Workbench PackRepo directory path, see Tools > Options > CMSIS-Pack > Local Pack Repository. Figure 6.
