# Use SWD debug download the MDK-ARM

To illustrate, here will be used as an example STM32F103C8T6.

**SWD interface to download programs in MDK-ARM**

1.First need to Open Debugger of SWD interface CLK, DIO, GND STM32F103C8T6 based target board in PA13, PA14 and GND are connected and open MDK-ARM.

2.Click Project, Option for Target'XXX 'or use the corresponding shortcut icon Alt + F7 or click on the toolbar to open the configuration options.
