The Nucleo-L4R5ZI is a board from ST's Nucleo family supporting a ARM Cortex-M4
|
|
STM32L4R5ZI microcontroller with 640KiB of RAM and 2MiB of ROM Flash.

## Flashing the device
|
|
|
|
### Flashing the Board Using OpenOCD
|
|
|
|
The ST Nucleo-L4R5ZI board includes an on-board ST-LINK programmer and can be
|
|
flashed using OpenOCD.
|
|
@note The latest release of OpenOCD doesn't contain support for this board,
|
|
so a recent development version (including http://openocd.zylin.com/#/c/4777)
|
|
must be built from source to be able to flash this board.
|
|
|
|
To flash this board, just use the following command:
|
|
|
|
```
|
|
make BOARD=nucleo-l4r5zi flash -C examples/hello-world
|
|
```
|
|
|
|
### 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-l4r5zi 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).
|
|
|
|
## 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 LPUART1.
|
|
|
|
The default baud rate is 115 200.
|
|
|
|
Use the `term` target to open a terminal:
|
|
|
|
make BOARD=nucleo-l4r5zi -C examples/hello-world term
|
|
