  • Upgraded: Eclipse version to 2019.12 (Eclipse Platform 4.14.0 / CDT9.10.0).
  • Upgraded: GNU ARM Embedded Toolchain to GCC9-2019-q4-major.
  • Upgraded: GNU make 4.2.1 is now integrated on IDE on all OS-es.
  • Upgraded: Version v8 of MCUXpresso Config Tools.
  • Upgraded: FreeRTOS TAD synchronization with FreeRTOS 202002.00.
  • Upgraded: newer SEGGER J-Link software (v6.80d).
  • Upgraded: newer PEmicro plugin (v4.6.9).
  • Added RT500 B0 support.
  • Added flash programming support for QN9090/JN5189.
  • Added KW37/KW38/K39 B0 support.
  • Improvement: [RT500/RT600] Extended flash drivers to support boards potentially wired in a different way from the EVKs with regards to the reset pin used for the external flash device.
  • Improvement: [RT500/RT600] Flash erase performance of RT600 rev B0 flash driver (~30% speed increase).
  • Improvement: 'Delete' option added for plugin SDKs. Now the removal option should be similar with the file system SDKs.
  • Improvement: Added Help -> "MCUXpresso IDE Save Info For Support" option intended to gather enough information to help reporting an issue:
    • MCU IDE installation details
    • Files from workspace
    • Information about Installed SDK
    • Workspace log file

        User is encouraged to use this option when reporting an issue and to also attach the generated zip file to help         development team to easier trace the reported problem.

  • Improvement: added new control to manage the maximum number of child expressions that are evaluated in advance by the Live Variables service. This improves the Global Variables window responsiveness for instance when large structures are displayed. New control available on Eclipse Preferences -> MCUXpresso IDE -> Debug Options -> "Number of subexpressions proactively evaluated by Live Variables service". Default is 2 set as depth.
  • Improvement: expressions added in Global Variables are now persistent between debug sessions.
  • Fixed: Error reported while importing SDK example and changing to Newlib (semihost).
  • Fixed: LinkerScript awareness reports fails on /DISCARD/ sections.
  • Fixed: IDE freeze and high CPU power consumption while debugging with Segger debug probe and disconnecting the USB cable.
  • Fixed: SDK import project example copies wrong header file in the case of multiple files with the same name.
  • Fixed: Unticking the "Redirect SDK PRINTF to C library printf" does not reset the ticking settings.
  • Fixed: [LPC11U68] A modified register in peripherals view alters other registers.
  • Fixed: [RT600] Debug error using LinkerServer if RT685 previously went to deep sleep state.
  • Fixed: [RT600] Unable to use "Restart" for debug session on RT600.
  • Fixed: [LPC43xx] "Wrong field format" displayed for SPI peripheral registers on LPC43xx.
  • Fixed: [RT1170] breakpoint support for CM4.
  • Fixed: "Hide Installed" within SDK installer view should be unchecked by default.
  • Fixed: Include directory path for the proper newlib.h is missing when newlib-nano spec is used.
  • Fixed: Global Variables showing negative timestamps after "Clear Data" is used.
  • Fixed: Exception thrown after trying to delete a closed project.
  • Fixed: SDK plugins generated with the IDE contains keywords of examples that are missing in the SDK package.
  • Fixed: ELF parsing issue which in some particular circumstances could cause incomplete flashing of programs generated using user-defined linker scripts (for example tfm SDK examples).
