Since NXP acquired Freescale and the Kinetis line of microcontrollers, they have been (gradually) migrating the Kinetis ecosystem from the (Eclipse+GNUARM-based) Kinetis Design Studio (KDS) to the (Eclipse+GNU Make-based) MCUXpresso IDE. While many MCUs within the Kinetis family are now supported by the MCUXpresso IDE, the Kinetis Bootloader (KBOOT) is not yet supported.
MCUXpresso is actually a constellation of 3 tools: The MCUXpresso IDE, the MCUXpresso config tools (which are incorporated into the IDE, and installable separately if a different IDE - such as MDK or IAR - is used), and the MCUXpresso SDK (formerly the Kinetis SDK or KSDK). The SDK tool is actually an online SDK generator.
Caution: Unsupported Devices
The Kinetis SDK (KSDK) and Kinetis Bootloader (KBOOT) do not support the entire line of Kinetis microcontrollers. Before designing a microcontroller into a project, check for KSDK and KBOOT support. Search for part family support at the [MCUXpresso SDK online builder](https:
