Nothing happens runnign blinky

Hi all, I'm new to embedded design - but hopefully not a complete novice.

I tried to follow the steps for blinky but nothing happens when I copy the .bin file to the root directory of the drive that shows up when I plugin my board.

Windows 10 (Enterprise) - Device Manager tells me that I have an MBED microcontroller USB device Drive shows up as NODE_F411RE I'm using the ST32 Nucleo F411RE

Blinky compiles fine and i'm sure I targeted the correct chip - (as instructed I double clicked the MBED.HTM on the drive).

Is the copying of the .bin file the 'flashing' operation? What might I be missing?

When I use IAR workbench I have no problems, it connects to the board and steps through the code fine.

Cheers

Sean

Hello Sean,

Yes, flashing the board is just copying the .bin file into on to the flash memory. However, after you done flashing/copying, you need to press the reset button to restart the board and to run the code.

Thank you, Peter, Mbed Team

This isn't the problem - i have reset, and unplugged the usb - even - nothing happens. Could it be a driver problem?

Hi Sean, Can you show us your Mbed online compiler screenshot and your NODE_F411RE drive folder?

Thank you, Peter, Mbed Team
