## Overview
|
|
|
|
The STM32L476GDISCOVERY is an evaluation board with the ARM Cortex-M4 based
|
|
ultra-low power microcontroller STM32L476VGT6 with 128KiB of RAM and 1MiB of
|
|
ROM Flash.

## 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=stm32l476g-disco PROGRAMMER=cpy2remed flash
|
|
```
|
|
@note This PROGRAMMER was tested using ST-LINK firmware 2.37.26. Firmware updates
|
|
can be found on [this STM webpage](https://www.st.com/en/development-tools/stsw-link007.html).
|
|
|
|
## Accessing RIOT shell
|
|
|
|
Default RIOT shell access utilize VCP (Virtual COM Port) via USB interface,
|
|
provided by integrated ST-LINK programmer. ST-LINK is connected to the
|
|
microcontroller USART2.
|
|
|
|
The default baud rate is 115200.
