Flashing the device
Flashing the Board Using OpenOCD
The ST Nucleo-F446RE board includes an on-board ST-LINK V2 programmer. The easiest way to program the board is to use OpenOCD. Once you have installed OpenOCD (look here for installation instructions), you can flash the board simply by typing
and debug via GDB by simply typing
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.
Supported Toolchains
For using the ST Nucleo-F446RE board we strongly recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.
