On the DA16600 EVK, the DA14531 debug interface can be connected to the higher numbered COM
port that is created when the USB cable is connected to
CN1
.
To enable the DA14531 debug interface,
SW3
and
SW7
must be set as follows:
Switch Pin
Description
Relevant pin
Setting
SW3
1
Enables UART1 of DA14531 (1-wire UART)
DA14531
P0_5/WLAN_ACT
OFF
2
Enables UART1 of DA14531 (1-wire UART)
DA14531
P0_5/WLAN_ACT
OFF
SW7
5
Enables UART debug of DA14531 (UART2 RX)
DA14531
P0_8/DEBUG
ON
6
Enables UART debug of DA14531 (UART2 TX)
DA14531
P0_9/DEBUG
ON
Once the switches are set properly, open a serial terminal application and select the higher
numbered COM port.
Configure the higher numbered COM port as follows:
Settings
Value
Baud Rate
115200
Data Bits
8
Parity
None
Stop Bits
1
Flow Control (HW/SW)
None
Open a second serial terminal application and connect to the DA16200 debug console and run the
“reboot” command.
The following output will appear in the DA14531 debug console:
user_on_init

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
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:
