Summary of Changes - version 11.7.1 - March 2023

  • Upgraded: Newer SEGGER J-Link software (v7.86e).
  • Upgraded: Newer PEmicro plugin (v5.5.5).
  • Upgraded: Version v13.1 of MCUXpresso Config Tools.
  • Added support for LPC553x/S3x revision A1 device.
  • Added support for LPC860 revision A1 device.
  • Added support for KW45/K32W1 revision A2 device.
  • Improvement: [SWO] Added preference for SWO ITM rxBuffer reading timeout in Preferences -> MCUXpresso IDE -> SWO Trace -> ITM_RxBuffer send timeout. This is intended to allow timeout increase in case user determines the application is not able to consume full amount of (so it will appear to lose) data sent by host debugger with the current timeout settings.
  • Fixed: [Debug] Can't create a new launch configuration after using GUI Flash Tool on PEmicro.
  • Fixed: [X-KW45B41Z-EVK][MCU-Link] Debug error reported when using MCU-Link firmware 3.x.
  • Fixed: [Debug][PN7642] Update reset script to fix Restart behavior in the IDE (not fully performing reset on certain clocks / peripherals).
  • Fixed: [Energy Measurement][Power Profile] Trigger configuration is visible for LPC-Link2 probes.
  • Fixed: [SWO] Starting debug session with SWO counters or interrupts views opened results in error.
