3.3 Serial and Debug Adapter
The FRDM-KW41Z development board includes OpenSDA v3.0-a serial and debug adapter circuit that
includes an open-source hardware design, an open-source bootloader, and debug interface software. It
bridges serial and debug communications between a USB host and an embedded target processor as
shown in Figure 3. The hardware circuit is based on a NXP Kinetis K20 family microcontroller (MCU)
with 128 KB of embedded flash and an integrated USB controller. OpenSDAv3.0 comes preloaded with
the DAPLink bootloader - an open-source mass storage device (MSD) bootloader and the DAPLink
Interface firmware, which provides a MSD flash programming interface, a virtual serial port interface,
and a CMSIS-DAP debug protocol interface. For more information on the OpenSDAv3.0 software, see
mbed.org and
