The mbed serial port works by default on Mac and Linux, but Windows needs a driver. These instructions explain how to setup the mbed Microcontroller to use the USB serial port on Windows. Download the mbed Windows serial port driver¶ Download the installer to your PC, e.g. Download latest driver. Run the installer¶. Sep 17, 2020 Just for sure. Do you have ST-link driver installed? In the windows device manager must be visible “ST-Link Debug” under “USB devices”. The 2MB disc drive are visible without the ST-link driver but for full features you need that driver. So if you have not the driver already installed, do it and try it again.

Mbed 2 is now deprecated. For the latest version please see the Mbed OS documentation.

The mbed serial port works by default on Mac and Linux, but Windows needs a driver. These instructions explain how to setup the mbed Microcontroller to use the USB serial port on Windows.
1. Download the mbed Windows serial port driver¶
Download the installer to your PC, e.g. your desktop.
2. Run the installer¶
With your mbed plugged in, and no explorer drive windows open, run the installer:
It will take some time (especially on Vista), and pop up a few 'unsigned driver' warnings, but after a while you should have a Serial port.

Troubleshooting
If you have multiple mbed microcontrollers, but the serial port only appears for one of them:
- Make sure you run the installer for every mbed; windows loads the driver based on the serial number, so it needs to be run for each mbed you use
If the installer fails because 'No mbed Microcontrollers were found':
- Check your mbed Microcontroller is plugged in
If the installer reports the message 'mbedWinSerial_nnnnn.exe is not a valid Win32 application':
- It is likely you are using Internet Explorer to download the installer file, which sometimes seems to only download part of the installer application for an unknown reason
- To solve this, download the installer with a different browser (Firefox, Chrome), and try again; this should solve the issue.
If the Installer appears to hang:
- Check if windows has popped-up a 'unsigned driver/permission' window; these often get hidden behind other windows with nothing to indicate so in the taskbar! Windows may be waiting for you to click 'OK'!

Block devices are the basic building block of storage solutions in Mbed OS.
File systems are backed by blockdevice implementations. The BlockDevice API performs the low-level interactions with the hardware storage. To add your own block device implementation, we recommend you inherit from the BlockDevice class. For details on how to extend the BlockDevice interface, please refer to the and implementing BlockDevice section below.
Assumptions
Defined behavior
- Erase leaves memory as undefined. It does not set memory to a predetermined value.
Undefined behavior
- Programming without erase is undefined behavior.
Notes
Erase, program and read block sizes may not be the same; however, they must be multiples of one another.
Implementing BlockDevice
You can find the BlockDevice class on the master branch under the features/storage/blockdevice path in Mbed OS.

One way to add tests for new block devices is to copy an existing implementation, such as HeapBlockDevice, and change the block device class to your own. You can find tests under the top level TESTS folder in the Mbed OS repository.
