How to start WIZwiki-W7500 Board

When you get a WIZwiki-W7500 platform board first on your hand, the serial driver installation and hardware test are needed. Because WIZwiki-W7500 uses CMSIS-DAP firmware writing and does serial communicate through UART1 on W7500 (Target MCU).


To install the serial driver

To install the serial driver from ARM mbed, please refer to the below link.


Hardware self-test

WIZwiki-W7500 has a built-in default firmware. You can do self-test with the default firmware as below.

Test Sequence

1. Connect Ethernet cable, USB cable to WIZwiki-W7500. If you have a SD card, insert the SD card.

2. Run the Device Manager in Control panel and check which COM port is allocated to the USB port on WIZwiki-W7500.

3. Press Reset SW, then LED 'D4' on WIZwiki-W7500 will be turned on. If D4 is turned off, then press the Reset SW again.

<Serial setting>
Baud rate : 115200
Data bits : 8
Parity : None
Stop bits : 1
Flow : None

4. If you have a SD card, the state of D4 will turn like this: White => White Blink => Yellow.

The following message prints out to the serial port.
