| <h2>Hardware Requirements </h2> |
| <p>The CMSIS-DAP Firmware is designed for Debug Units that fulfil the following hardware requirements:</p> |
| <ul> |
| <li>Cortex-M0, Cortex-M0+, Cortex-M3, or Cortex-M4 processor-based microcontroller.</li> |
| <li>CPU Clock: 48MHz or higher; microcontroller must have a SYSTICK timer.</li> |
| <li>RAM: 8KB or more; Flash ROM: 16KB or more.</li> |
| <li>Full-speed or High-speed USB Device Peripheral.</li> |
| <li>7 standard I/O pins for JTAG/SWD Device Interface.</li> |
| <li>optional 2 I/O pins for Status LEDs.</li> |
| <li>optional UART to support SWO capturing (Rx pin connected to SWO)</li> |
| </ul> |
| <h2>CMSIS-DAP Firmware </h2> |
| <p>The CMSIS-DAP Firmware can be configured for a new Debug Unit using at least the <a href="http://www.keil.com/mdk5" target="_blank">Keil MDK-Plus or MDK-Professional Edition</a>. Reference implementations are provided as source code with complete project files and may be used as starting point for the firmware deployment to a new Debug Unit.</p> |
| <p>The folder <b> .\Firmware\Config</b> contains a template of the <b>DAP_config.h</b> configuration file. Various adaptations for different target hardware are provided.</p> |

| <p>The CMSIS-DAP Firmware is designed to execute on a Debug Unit that is using a Cortex-M0, Cortex-M0+, Cortex-M3, or Cortex-M4 processor-based microcontroller. To deploy the firmware to a new Debug Unit copy an existing firmware adaptation to a new folder. For example, copy the folder .\Firmware\XMC4200 to a folder called .\Firmware\MyDebugUnit.</p> |
| <p>To following steps describe the adaptation of the CMSIS-DAP Firmware to a new Debug Unit:</p> |
| <ol type="1"> |
| <li><a class="el" href="group__DAP__ConfigMCU__gr.html">Debug Unit Processor</a> : Select the microcontroller and replace the CMSIS-Core (Cortex-M) files.</li> |
| <li><a class="el" href="group__DAP__ConfigIO__gr.html">Configure I/O Ports and Debug Unit</a> : Adapt the I/O Ports and specify other parameters for the Debug Unit.</li> |
| <li><a class="el" href="group__DAP__ConfigUSB__gr.html">Configure USB Peripheral</a> : Adapt the USB Peripheral to the microcontroller.</li> |
| <li><a class="el" href="group__DAP__USART__gr.html">Connect SWO Trace</a> : Optional you may add a CMSIS-Driver USART to interface to SWO.</li> |
| <li><a class="el" href="group__DAP__Vendor__gr.html">CMSIS-DAP Vendor Commands</a> : Optional you may add vendor specific commands to the Debug Unit.</li> |
| <li><a class="el" href="group__DAP__ConfigFlash__gr.html">Flash Program Firmware</a> : Program the adapted firmware to the Flash ROM of the new Debug Unit.</li> |
| <li><a class="el" href="group__DAP__Validate__gr.html">Validate Debug Unit</a> : Validate the CMSIS-DAP firmware of the new Debug Unit. </li> |
