Default bus-clock, stack size
Great portability across Cortex-M devices
Easy to use for developer, difficult to design by silicon or board vendor (but we provide the HDK)
DAPLink – interface chip firmware (CMSIS-DAP compatible)
Inter-linking problems – target and interface device had tight dependency
It was ARM proprietary license
Not only silicon vender, but also OEM, board vender can re-use the design resource
No firmware source code
Interface chip – NXP devices (LPC11U35, Kinetis K20DX), Atmel (SAM3U2C) for reference
No need SWD/JTAG debug adapter
Library – chunk of component and schematics for eagle
Design – actual board layout, ready to production
We will check acceptance criteria, and them merge your pull request.
OSH Park is a community printed circuit board (PCB) order.
