IN25 | Interface for SDT Board
Interface for SDT32620B and SDT32625B
The Interface programs and debugs SDT Board. An Interface is connected to SDT Board via the DAP Station and is powered by a PC through a USB cable. It is important that you use the right Interface for your Target MCU, since there are designated Target MCUs that are compatible with a certain Interface. IN25 is Interface for SDT32620B and SDT32625B.
2. DAPLink Interface Firmware
This programming process uses the Arm Mbed DAPLink to drive the Interface. The following functions
1) Drag-and-drop Programming (MSC)
The SDT board is connected to the computer and drag-and-drop programming can be performed on the flash of the SDT board.
2) Virtual Serial Port (CDC)
Serial connection from the SDT board to PC. The code written by the PC goes into the Interface and SDT board.
3) CMSIS-DAP Based Debugging (HID)
This is a compatible feature when you want to see detailed events that occur on the SDT board and Interface with an advanced debugger such as Keil or GDB.
3. DAPLink Programming Mode
DAPLink has two programming modes.
First, you can write to the Interface flash to update the firmware of the Interface. It’s called bootloader mode. We recommend that you never update to an unverified version. It may cause serious problems.
Second, you can write to the memory of the SDT Board for programming. You can debug the SDT Board using this mode.
4. How to connect Interface with SDT Board and DAP Station
- Prepare the Interface suitable for the SDT Board.
- Connect SDT Board to DAP Station.
- Use SD-TAG to connect Interface to DAP Station.
- Connect PC to Interface using Micro B-Type USB.
- Supply power to SDT Board using DAP Station’s Micro B-Type USB Connector.
- Use the online compiler on the Arm Mbed homepage or CLI to program and compile.
- Move the compiled file (.bin or .hex) into the DAPLink drive.
- For efficient connection, the SD-TAG of the DAP Station and SD-TAG Pin of the IN25 is
- The IN25 supports SWD and UART communication for programming and debugging. It does not
5. How to download a firmware of IN25
The IN25 comes with the bootloader pre-installed. In order to download and update firmware, you
must activate the bootloader. For bootloader activation, connect the Interface to power while
pressing the Reset switch. When the Reset switch is operated, the bootloader turns on and
connects to “MAINTENANCE” driver.
Drag-n-drop the “.bin” file to the “MAINTENANCE” folder.
- For firmware and bootloader, check the IN25 Page.
