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.

H/W Introduction 

      1. ED22 board reset.

      2. Target MCU(STM32L443/STM32F412) reset.

      3. Micro USB connector.

      4.10pin FFC connector.

ED22 Firmware Update

When a new ED22 is plugged in to your machine, it will not contain valid any firmware, and so will appear as a disk drive called "CRP Disabled" as.

To progam the ED22, follow these steps:

    Step1: plugging ED22 in PC with the target mcu reset button held down.

    Step2: Open the drive, and delete the file called "firmware.bin"

    Step3: Copy the .bin file onto the "CRP Disabled" drive.

    Strp4: Press ED22 board reset to restart, then you can see a disk drive called DAPLink.

Bin files:

    1. STM32L443: WISE1511/WISE1540

    2. STM32F412: WISE1530

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 debug 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

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

• pyOCD
• uVision
• IAR
