Summary of Changes - version 11.3.0 - January 2021

  • Upgraded: Eclipse version to 2020.06 (Eclipse Platform 4.16.0 /  CDT9.11.1).
  • Upgraded: IDE now integrates with OpenJDK8.
  • Upgraded: GNU ARM Embedded Toolchain to GCC9-2020-q2-update.
  • Integrated: GNU test coverage (gcov) and performance analysis (gprof) tools and Eclipse plugins.
  • Upgraded: Version v9 of MCUXpresso Config Tools.
  • Upgraded: Newer SEGGER J-Link software (v6.88c).
  • Upgraded: Newer PEmicro plugin (v4.8.5).
  • Added: i.MX RT1170 B0 support.
  • Added: i.MX RT1024 support.
  • Added: RT500 B2 support.
  • Added: K32W061 support.
  • Added: K32W041AM support.
  • Added: LPC55S06 support.
  • Added: MCU-Link probe debug support.
  • Feature: Added Energy Measurement view, aiming to replace the Power Measurement view. Main capabilities:
    • The new view comes with the same feature-set as the old Power Measurement view;
    • From a GUI perspective, it offers consistent look & feel with other views that display and controls graphs (e.g. Global Variables, SWO-related views);
    • Compatible with existing LPCXpresso boards having on-board power measurement circuits;
    • Power and energy estimation capability: in order to enable power/energy measurement/estimation the user should add a reference voltage in the Config tab section from Energy Measurement view. For convenience and more precise measurement, the user can press "Read from target" which will automatically generate a reference voltage computed as an average value (of the voltage) measured for the last 500msec. Energy and power will be displayed in the status line of the plot area, showing the min/max/average power values and the energy value for the measurements visible in the graph, or over a particular time range selection.
    • Multiprobe and multiview support: the feature is capable to open multiple views, each view can be connected to a different probe (that is capable to measure analog). The probe can be selected from Probe Discovery feature available in the Energy Measurement view toolbar.
    • Data collecting during an out-of-debug session and also during an active debug session;
    • Data collecting with an active debug session while the core is in debug mode. Behavior is controlled via toolbar buttons;
    • Configuration of the server-side (rltool) and of the IDE using the Config tab within the view;
    • Import/Export data functionality for offline analysis: (buttons on the Energy view toolbar). The user is able to save (Export data, in a zip format) the data collected within the view, having the possibility to load the saved data (Import data) later, in the same view or another one. Loading saved data in the Energy Measurement is not requiring physical connection to the target;
    • Extended LPC-Link2 support for all targets having onboard measurement circuit: LPCXpresso546x8/540xx/54S0xx, LPCXpresso54102, LPCXpresso51U68/54114, QN90x0/JN518x/K32W0x1. As a side note, if there is any other LPC-Link2 board having power measurement capability, the user can use an existing configuration (and change the resistor value if necessary);
    • See MCUXpresso_IDE_Energy_Measurement.pdf (or Help -> Help Contents) for details.
  • Feature: Auto-debug slave project(s) for multicore projects option becomes default option for multicore debug purpose (for LinkServer debug connection only). That means, in the case of multicore projects on which primary project refers one or several secondary projects, debug sessions will be automatically started for secondary projects after initiating debug with the primary project.
    • Option is set by default on: Window -> references -> MCUXpresso IDE -> Debug Options -> LinkServer Options -> Miscellaneous -> Enable Auto-debug slave project(s) for multicore projects.
    • If you don't want to have this feature enabled (so if you want to start debug sessions for each core independently), uncheck this option.
    • Similar, Auto-debug slave project(s) for multicore projects option becomes default option for multicore debug purpose for PEmicro too. Option is set by default on: Window -> Preferences -> MCUXpresso IDE -> Debug Options -> PEMicro Options -> Enable Auto-debug slave project(s) for multicore projects.
  • Improvement: Enhance SWO views:
    • SWO Config: added new Tab for data traffic statistics, configuration for ITM Stimulus ports;
    • SWO Profile: added samples and details tabs;
    • SWO Data: added plot (similar to Global Variables);
    • SWO Stats: moved inside SWO Config;
    • ITM Console: added one tab for each stimulus port.
  • Improvement: [RT600] Clean up on RT600 flash drivers:
    • Add drivers for MXIC_OPI connected via FlexSPI_A port;
    • Add drivers for QSPI drivers (SFDP) connected via FlexSPI_B port;
    • Add drivers for QSPI drivers (SFDP) connected via FlexSPI_A port;
    • Remove MIMXRT600_SFDP_* drivers generated by the old project (SDK now references the new drivers).
  • Improvement: Drop-down boxes from several tables require two user operations for reaching the actual items from the list. Reduced now to a single operation (single click).
  • Improvement: Extend CLI functionality - Add new command to list SDK info:

  -filter=<string> : filters the available information based on regex expression string. e.g. -filter=K64 will display all data containing K64 string. See SDK command line documentation within the layout (MCUXpresso_SDK_Command_Line_User_Guide.pdf).

  • Improvement: Merge c_include path section into cpp_include path section for cpp project in project settings.
  • Improvement: New project wizard is now capable to handle HW with dual primary/secondary roles (i.e. RT1170). From SDK Wizard page, any core can be selected according with the secondary/primary SDK description, plus it can be selected as standalone (application).
  • Improvement: Community forum accessible now from the main toolbar too (together with the older link from Help->MCUXpresso IDE support forum). The default selection will open the community web inside the IDE. If you want to set the default browser as external browser, use Window->Preferences->General->Web browser->"Use external web browser".
