Flashing the device
Flashing the Board Using OpenOCD
The ST Nucleo-F401RE 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-F401RE board we strongly recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.
Issues with old Hardware Revisions
Some Nucleo 64 Boards come in different hardware revisions, which is located on a sticker at the backside of the board. As discussed in issue #6721, there are some issues with the external clock sources in revisions smaller than C-03. (This would also be true for all boards with board ID MB1136). The revision C-01 has a different configuration for the high speed external clock (HSE), which is used in RIOT. This could be fixed by reconfiguring some solder bridges as mentioned in the user manual, section 6.7.1. The other issue is, that revision C-01 also has no 32kHz oscillator, so the RTC module of RIOT cannot be used.
