5 Wi-Fi Provisioning Setup
5.1 DA16600 Connecting the Board
This section describes the installation procedure for the drivers, the configuration of the serial port,
and the steps needed to verify the connection with the PC as well as solutions to problems that may
occur.
On the first connection to a host PC running Microsoft Windows, the system detects several devices
and automatically installs all necessary drivers. If the drivers are not automatically installed, you can
get them from the following URL: http://www.ftdichip.com/Drivers/CDM/CDM21224_Setup.zip.
The Windows driver creates two virtual COM ports. The first COM port (lower number, COM35 in this
example) provides a UART interface for debugging or firmware download between the PC and the
DA16600. See Figure 7.
Figure 7: Check COM Ports on Device Manager
5.2 Configure the Serial Port for UART
For a Windows Host, the Tera Term utility is used to fully validate the connection to the DA16600
EVK.
Tera Term is a free software terminal emulator (communication program) which supports multiple
communication including Serial port connections. Download Tera Term from https://ttssh2.osdn.jp.
Run the teraterm-x.yy.exe and follow the installation wizard.
To make sure that the communication between the DA16600 EVK and host PC is properly
established, you need to verify the UART connection between the two nodes. Do the following:
1. Connect the DA16600 EVK to the PC USB port via USB cable.
2. Verify that the host identifies two serial ports as shown in Figure 7 – the second is connected to
UART (see Section 5.1).
3. In the Windows Start menu, open Tera Term.
4. In the Tera Term: New connection dialog, do the following:
a. Select Serial.
b. Select the COM Port to use.
c. Click OK.

5. Select Setup > Serial Port and configure your UART port using the parameters as shown in
Figure 8.
6. Open the Lowest COM port number assigned to the DA16600 EVK.
Figure 7 shows which port number to select in Device Manager in Windows. Make sure that the
UART is configured as shown in Figure 8.
Figure 8: Serial Port Setup
5.3 Setup for Wi-Fi Provisioning Using Bluetooth® LE
DA16600 module may be used in a product like Wi-Fi door-lock where Wi-Fi is playing the main role,
and Bluetooth® LE assists with Wi-Fi Provisioning at the product's initial setup (Out-of-Box). A
Bluetooth® LE peer application (for example Android/IOS mobile application) interacts with users to
set up the DA16600 device – by giving Wi-Fi Provisioning information (for example, Wi-Fi Home
router's SSID, password, server info, and other).
Figure 9: Provisioning via Bluetooth® LE
To set up Wi-Fi provisioning:
1. Download Dialog WiFIProvisioning App at App Store and install it.
2. Check the prompt [/DA16600] #.
3. Run Provisioning App and follow the steps in Table 1.

6 Current Measurement
For detailed information on Sleep mode, see the Low Power Operation Mode section in DA16200
Datasheet [1]. To measure current waveform, connect the EVK's current measurement point (P1 and
P2) with the measurement instrument (KEYSIGHT 14585A).
Figure 10 shows a typical test setup environment.
Figure 10: Current Test Environment
For more details on using power meter kit, see DA16600_SB_Power_Meter_Kit_User_Manual [1].

8 Firmware Update
The security features of DA16600 support Secure Boot to avoid booting with fake or untrusted
images and to protect against hacking. The DA16200 SoC includes a security hardware block called
CryptoCell-312 (CC312). With proper security keys and certificates installed (in OTP and images),
the DA16200 can boot in secure mode.
DA16600 requires three images. With a serial terminal tool, each image can be loaded individually
into the flash:
●<Bootloader image>: also known as Second Bootloader
○DA16600_[image_type]-[vendor]-[major]-[minior]-
[customer_ver]_[sflash_model].img
– [Image_type]: Bootloader (FBOOT), Main (FRTOS), or DA14531 image
– [vendor]: Internal use by vendor
– [major]: Major version
– [minor]: Minor version or SDK patch version
– [customer_ver]: User-configurable customer version
– [sflash_model]: sflash model or type used
○For example: DA16600_FBOOT-GEN01-01-xxxxx-xxxxxx_AT25SL321.img
●<Main image>: includes RTOS and applications
○For example: DA16600_FRTOS-GEN01-01-xxxxx-xxxxxx.img
●<DA14531 image>:
○For example: DA14531_multi_part_proxr.img
8.1 Flash MAP
DA16200 provides two image sets: #0 and #1. It is possible to use these regions for each image set
and change the index of the booting image set. The default value of the Boot Index points to #0.
Table 2: 4 MB Serial Flash Memory Map
Address Item Size
0x0000_0000 2nd Bootloader 139 kB

NOTE
Secure Boot operation of the DA16600 FreeRTOS is supported in the DA16600 FreeRTOS SDK Official
Release version.
This feature is not available in the current Alpha Draft SDK package.

8.2 Bootloader Image
<Bootloader image> is also known as the second bootloader and is the first thing loaded into
memory for a factory-created DUT (for example with an empty flash).
Know that this image has SFDP information, which is important sflash type information, so always
load this image before loading the other images.
If you get a new SDK, then you always load the <Bootloader image> first.
1. Power on the DA16600 board.
2. At the [/DA16600] prompt, type reset to go to the Mask ROM prompt [MROM]. See Figure 14.
Figure 14: Mask ROM
3. At the [MROM] prompt, type loady boot. See Figure 15.
Figure 15: Bootloader Prompt on Command Window
4. Go to File > Transfer > YMODEM > Send to select the image file for the Bootloader. See
Figure 16.
○For example: DA16600_FBOOT-GEN01-01-xxxxx-xxxxxx_AT25SL321.img
○The result is printed at the end of the transfer. Ignore any messages like “err:..”

1. At the [MROM] prompt, type loady 23000. See Figure 17.
NOTE
The RTOS address map register depends on the flash memory size. Therefore, the address must be 0x23000
for boot index 0 or 0x1E2000 for boot index 1. In this case, at the [MROM] prompt, type loady 23000 or
loady 1e2000.

8.6 Serial Flash Recovery
When the serial flash is replaced, the flash memory map is changed, or if you think that the flash
memory is corrupted, then follow the steps to re-initialize or recover sflash and check the process:
1. Boot DA16600.
2. At the [/DA16600] # prompt, run reset command.
3. At [MROM] prompt, run sflash info command to read serial flash information.
For example, SFLASH: 1f421615.
This is the flash product ID of AT25SL321. See also the IDs below.
AT25SL321 : 1f421615
4. Run ymodem sfdp command.
5. In the build\SBOOT\SFDP folder, find Flash SFDP file that corresponds to Flash ID as
AT25SL321.bin.
6. Run sflash erase 0 400000 command [MROM] to erase the entire flash for recovery.
Know that this command can take a long time to complete. Wait until the [MROM] prompt appears
again.
7. Re-load all images in the specified order for serial flash recovery.
a. [MROM] loady boot.
b. [MROM] loady 23000.
c. [MROM] loady 3ad000.
8. Run command boot to boot DA16600.
The image version is printed.
9. Initialize NVRAM for Serial Flash Recovery with following commands:
[/DA16600] # nvram
[/DA16600/NVRAM] # nvedit erase sflash
[/DA16600/NVRAM] # nvedit clear
[/DA16600/NVRAM] # nvcfg update sflash
