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.
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:
