@brief Support for the STM32 Nucleo-c071rb
5+
6+
## Overview
7+
8+
The Nucleo-c071rb is a board from ST's Nucleo family supporting a ARM
9+
Cortex-M0+ STM32C071RB microcontroller with 24KiB of RAM and 128KiB of Flash.
10+
11+
## Pinout
12+
13+
See Board Manual referenced below, section 7 pages 19-21.

## Flashing the Board Using ST-LINK Removable Media
38+
39+
On-board ST-LINK programmer provides via composite USB device removable media.
40+
Copying the HEX file causes reprogramming of the board. This task
41+
could be performed manually; however, the cpy2remed (copy to removable
42+
media) PROGRAMMER script does this automatically. To program board in
43+
this manner, use the command:
44+
45+
```
46+
make BOARD=nucleo-c071rb PROGRAMMER=cpy2remed flash
47+
```
48+
49+
@note This PROGRAMMER was tested using ST-LINK firmware 2.37.26. Firmware updates
50+
could be found on [this STM webpage](https://www.st.com/en/development-tools/stsw-link007.html).
