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:
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:
- Note
- This PROGRAMMER was tested using ST-LINK firmware 2.37.26. Firmware updates could be found on this STM webpage.
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.
