## Flashing the Board Using ST-LINK Removable Media

On-board ST-LINK programmer provides via composite USB device removable media.
Copying the HEX file causes reprogramming of the board. This task
could be performed manually; however, the cpy2remed (copy to removable
media) PROGRAMMER script does this automatically. To program board in
this manner, use the command:

```
make BOARD=nucleo-c071rb PROGRAMMER=cpy2remed flash
```

@note This PROGRAMMER was tested using ST-LINK firmware 2.37.26. Firmware updates
could be found on [this STM webpage](https://www.st.com/en/development-tools/stsw-link007.html).

/**
* @defgroup boards_stm32c0116-dk STM32C0116-DK
* @ingroup boards
* @brief Support for the STM32C0116-DK board.
*
* ### General information
*
* The ST [STM32C0116-DK](https://www.st.com/en/evaluation-tools/stm32c0116-dk.html)
* is an evaluation board supporting a ARM Cortex-M0 STM32C011F6 microcontroller
* with 8KB of RAM and 32KB of ROM Flash.
*
* ### Pinout
*
* See [this application note as reference](https://www.st.com/resource/en/application_note/an5673-getting-started-with-stm32c0-mcu-hardware-development-stmicroelectronics.pdf).
* This means the responsibility is on the firmware configurer to take special care when configured IO, ensuring that
* ports are not conflicting on each pin.
*
* ### Flash the board
*
* The STM32C0116-DK board includes an on-board ST-LINK programmer and can be
* flashed using OpenOCD.
*
* To flash this board, just use the following command:
*
* ```
* make BOARD=stm32c0116-dk flash -C examples/hello-world
* ```
*
* ### UART Terminal Interaction
*
* Due to the limited number of pins, to get stdio UART traffic, use a USB->UART adapter
* like the CP2104 from Adafruit (http://adafru.it/954). Connect the adapter's TX line
* to the MCU RX pin (PB6, Pin 8) and the adapter's RX line to the MCU's TX pin -
* (PB7, pin 1)
