Abstract
The DA16200 is a highly integrated ultra-low power Wi-Fi system on chip (SoC) that allows users to
develop a complete Wi-Fi solution on a single chip. This document is a DA16200 getting started

3 Overview
The DA16200 is a highly integrated ultra-low power Wi-Fi system on chip (SoC) that allows users to
develop Wi-Fi solutions using a single chip.
Evaluation Kits and SDKs are provided to simplify the process of starting a project with the DA16200
or the DA16600.
This document provides a step by step guide to get started using the EVKs & SDKs by providing
details on:
●The DA16200 and DA16600 Evaluation Kit hardware (see Section 4)
●How to connect to the EVKs (see Section 4.4)
●How to download firmware to the DA16200/600 (see Section 4.5)
●How to provision and test the Wi-Fi connection (see Section 4.6)
●How to install the development tools (see Section 5)
●How to install the SDK (see Section 5.6)
●How to build an application (see Section 5.7)
●How to debug an application (see Section 5.9)
●How to perform various test procedures to demonstrate the capabilities of the
DA16200/600 (see Section 6)
Once completing these steps, the EVK and development environment is ready for developing a
complete Wi-Fi solution.
If the Wi-Fi solution being developed is based on a host MCU that uses the DA16200/600 only as a
Wi-Fi communication interface through AT Commands, then a prebuilt firmware image can be used
to develop that solution. For details on how to use AT Commands see the following documents:
●UM-WI-003 DA16200 AT-Command User Manual [6]
●UM-WI-038 DA16200 Getting Started with AT-Command for AWS-IoT [7]
If the Wi-Fi solution being developed requires special functions or it is a standalone solution using
only the DA16200/600, then the SDK can be used to develop a new firmware image for that solution.
For more details on how to use the SDK to develop an application, see the following documents:
●UM-WI-046 DA16200 FreeRTOS SDK Programmer Guide [2]
●UM-WI-xxx DA16200 Example Application Guide [3]

of SW5. The current consumption of the DA16200 and the DA14531 can be measured
simultaneously.
For more details on the DA16600 EVK see the DA16600 DEVKT Electric Schematic [14].
For more detailed information on using the power meter kit, see UM-WI-041 DA16600 EVK Pro User
Manual [10].
4.4 Connecting to the EVKs
Configuring the DA16200/600 Serial Debug Interface
The DA16200/600 provides a command/debug interface on uart0 for performing configuration and
diagnostic functions.
When the EVK is connected to the USB port (CN6 on the DA16200 EVK or CN1 on the DA16600
EVK), two virtual COM ports are created.
On Windows the two COM ports are seen in the device manager (see Figure 3).
Figure 3: Windows - COM Ports
NOTE
On Windows, If the ftdi serial driver installation does not happen automatically, the drivers can be
downloaded from the following URL and installed manually:
http://www.ftdichip.com/Drivers/CDM/CDM21224_Setup.zip
On Linux the COM ports are created in the /dev directory as ttyUSBxdevices.
$
$ ls -l /dev/ttyU* List the available ttyUSB serial ports.
crw-rw---- 1 root dialout 188, 0 Aug 25 10:26 /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 1 Aug 25 10:26 /dev/ttyUSB1
$
The lower numbered COM port is for the DA16200/600 debug interface.
The higher numbered COM port is for the DA16200/600 ATCMD interface.
NOTE
On the DA16600 the higher numbered COM port can also be configured as the DA14531 serial debug
interface. See section 4.4.2.
A serial terminal application that supports Y-Modem is required to download the firmware to the
DA16200.
For Windows, the Tera Term terminal emulator program is recommended and can be downloaded
from: https://ttssh2.osdn.jp.

For Linux, the minicom terminal emulation program is recommended and can be installed using:
$
$ sudo apt install minicom Command to install minicom.
$
Once the terminal emulation application has been installed, Connect the USB cable to the EVK (CN6
on DA16200 EVK or CN1 on DA16600 EVK) and start the terminal emulation program.
In the terminal emulation program, go to the Serial Port Setup and select the lower number COM

Configuring the DA14531 Serial Debug Interface (DA16600 EVK only)
This section is for DA16600 only and is required for special cases where access to the DA14531 BLE
devices debug terminal is required.
The DA16600 EVK contains the DA14531 BLE device which is used for provisioning of the DA16600
Wi-Fi interface using a mobile application.

4.5 Updating the Firmware
When first receiving an EVK, the firmware must be updated to the latest version.
Prebuilt versions of the firmware for DA16200 and DA16600 can be downloaded from the Dialog
website:
https://www.dialog-semiconductor.com/products/wi-fi
The firmware images can be found under the Resources page for the specific device in a file typically
named “FreeRTOS SDK Image”.
Alternately, the DA16200/600 SDK can be used to rebuild the firmware images as described in
Section 5.
There are two firmware images for the DA16200:
DA16200_FBOOT-GEN01-01-834dea5b8_W25Q32JW.img
DA16200_FRTOS-GEN01-01-866facc56-000000.img
There are three firmware images for the DA16600 since it also requires the DA14531 firmware
image:
DA16600_FBOOT-GEN01-01-834dea5b8_AT25SL321.img
DA16600_FBOOT-GEN01-01-834dea5b8_W25Q32JW.img

Firmware Update using Commands (Windows/Linux)
The following steps will load the firmware images onto the DA16200/600:
1. Connect the EVK to a PC using a Micro USB cable and configure the debug interface and serial
terminal as described in Section 4.4.1.
2. Power ON the DA16200/600 EVK.
3. At the [/DA16xxx] prompt, type reset to go to the Mask ROM prompt [MROM]:

4. Load each firmware image:
The FBOOT, FRTOS and optionally the DA14531 firmware images are downloaded individually.
Use the following process to download each firmware image:
a. At the [MROM] prompt, use one of the following loady commands to load the required
firmware images:
Table 7: FW Image loady Commands

loady 3ad000 1000 bin
For the DA16600MOD only.
Only needs to be downloaded for a new EVK
or if there is new DA14531 firmware available.
For example:
[MROM] loady boot Start the Y-Modem download protocol.
Load Addr: 000f6684
To cancel a session, press Ctrl+X
Load Y-Modem (Load Offset:f6684)
CCC
At this point, the DA16200 is waiting for the download to start.
b. In the terminal emulation program, start the Y-Modem file transfer:
●For Windows Tera Term:
Open the File tab and select Transfer->YMODEM->Send.
Navigate to where the firmware image is stored, choose the required firmware image and
start the download.
●For Linux minicom:
Press {Ctrl+A}+S and select ymodem from the menu.
Navigate to where the firmware image is stored, choose the required firmware image and
start the download.

NOTE
Ignore the “ err:..”messages.
d. Repeat steps a. through c. to download the FRTOS firmware image and then the DA14531
firmware image (if using DA16600MOD).
5. Run the firmware:
After all firmware images have been downloaded, run the boot command at the [MROM] prompt to
start the firmware:

Once the firmware is updated successfully, the device can be configured by doing the Wi-Fi
provisioning process. See Section 4.6 for details on how provision the Wi-Fi communication
interface.
Firmware Update using the Terra Term script (Windows only)
For Windows users, the firmware images can be downloaded automatically using a terra term script
as follows:
1. Once terra term is running and connected to the DA16200/600, open the Control tab and select
the Macro menu item.
When the MACRO: Open Macro file selection window opens, navigate to the directory where the
firmware images are stored and select the .ttl file (see Figure 4).
Figure 4. Open the Macro File
2. After opening the macro file, the DA16200/600 will reset, and the BOOT firmware image is
downloaded (see Figure 5).

Multi-Download Tool
A products manufacturing process requires that the firmware be download to many devices. To make
this process more efficient, the Multi-Download Tool can be used to download the firmware to
multiple devices at the same time. Please see the UM-WI-039 DA16200 DA16600 Multi Downloader
