ED22 Functions

There are three interfaces that ED22 board provides. These are drag-n-drop programming, a serial port and debugging support. In addition ED22 board firmware can be updated using the drag-n-drop programming interface of the bootloader.

ED22 Firmware Update

When you get a new WISE-ED22, you must perform the following steps to updated it's FW. Make WISE-ED22 suitable for your product.

Step1: Connect the WISE-ED22 to PC using micro-USB cable. Please hold down the button SW1 and press the button RST1 once, then release the button SW1 and you will  see the CRP DISABLD

Step3:Copy the WISE-ED22 FW that corresponding to target MCU onto the "CRP DISABLD" drive. 


Step4: Press ED22 board reset to restart, then you can see a disk drive called DAPLink.

WISE-ED22 FW binary files (you will see the binary file after uncompressed the *.zip) :

    1. STM32L443: WISE-1510/WISE-1511/WISE-1540

    2. STM32F412: WISE-1530/EPD-132

    3. STM32L486: WISE-1570

Using ED22

Drag-n-drop Programming

To use the ED22, simply connect to your PC with a micro-USB cable, and to the WISE-15XX board using a 10 pin FFC cable. You can drag and drop binary images onto the DAPLink disk drive, which will then be programmed into the target system.If errors are encountered, a file called "fail.txt" will appear with details.

Note that the ED22 has to contain the correct firmware to enable drag and drop programming.


Supported file formats:

  • Raw binary file
  • Intel Hex

Serial Port

The serial port is connected directly to the target MCU allowing for bidirectional communication. It also allows the target to be reset by

sending a break command over the serial port.

Supported baud rates:

  • 9600
  • 115200


Debugging can be done with any IDE that supports the CMSIS-DAP protocol. Some tools capable of debugging are:
