Please find attached a document detailing how to debug the Kinetis KE0x range of MCUs via LinkServer (CMSIS-DAP) debug connections using MCUXpresso IDE version 11.1.1 (or later).

This document and updates within the version 11.1.1 release of MCUXpresso IDE address an issue seen if attempting to debug these parts in earlier versions of MCUXpresso IDE.

Note: it is expected that the issues described in the attached document will be addressed in updated SDK releases for this range of MCUs for use with MCUXpresso IDE version 11.1.1 or later.

    • Fixed issue with handling of ld's PROVIDE keyword
  • Fixed issue with linker script generation related to placement of symbols for .ARM.exidx section (which could trigger issue with C++ exceptions)
  • Restructured way eGIT plugin integrated into IDE (to allow updating by the user). Supplied version also updated to v5.6.0
  • Updates to allow LinkServer debug connections (ie CMSIS-DAP) to i.MX RT6xx "rev B" silicon. Note that these changes mean that earlier i.MX RT6xx silicon can no longer be supported
  • Updates to LinkServer debug to provide support for debugging Kinetis KE0x. Note that manual changes to SDK 2.7.0 or earlier are required for this to be enabled
  • Preliminary LinkServer support for i.MX RT1170 devices
  • Fixed sector size issue with LinkServer flash driver for Kinetis KM3x devices
  • Fixed issue that prevented launch configuration creation (and hence debug) for multicore projects for preinstalled parts (LPC43xx and LPC54xxx)
  • Fixed issue with Peripheral View incorrectly handling 32-bit bitfields within peripheral registers
  • Fixed issue with Registers View such that modifying fields in xpsr could incorrectly modify other fields
  • Added mechanism to Preferences to allow default reset settings used when creating SEGGER launch configurations to be overridden for specific devices
  • Updated integrated version of MCUXpresso Config Tools to v7.0.1
    • TEE tool: Displays correctly inaccessible regions in "Memory attribution map" view
