Free and open implementation of the CMSIS-DAP debugger firmware

This is a free and open implementation of the CMSIS-DAP debugger firmware.

Both SWD and JTAG protocols are supported. However JTAG was not well tested due to lack of good targets. If you have any issues with it - let me know and I'll try to help.

To create a CMSIS-DAP compliant debugger, your platform must: Implement USB HID (and raw bulk for CMSIS-DAP v2) device able to receive and send arbitrary payloads Provide configuration file dapconfig.h with definitions for hardware-dependent calls Call dapinit() at the initialization time Call dapprocessrequest() for every received request and send…

D11-nano dbg: common questions

What microcontroller does the D11-nano dbg use?

The D11-nano dbg is built around the ATSAMD11C, from the Microchip SAM family.

How big is the D11-nano dbg PCB?

The D11-nano dbg measures 15.2 × 10.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the D11-nano dbg?

13 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the D11-nano dbg design files?

From the ataradov/free-dap repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the D11-nano dbg design in my own project?

Yes, under the terms of its BSD-3-Clause license, which ataradov chose for the repository.

Can I test firmware for the D11-nano dbg without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
