Introduction
This example demonstrates the use of the WINC1500 with the SAM Xplained Pro board to perform an OTA Firmware upgrade. It uses the following hardware:
- the SAM Xplained Pro.
- the WINC1500 on EXT1.
Main Files
- main.c : Initialize the WINC1500.
Usage
- You need to setup an HTTP server accessible via your Wi-Fi network. This HTTP server must have the "m2m_ota.bin" OTA firmware accessible at this location: http://SERVER_IP_ADDRESS/winc1500_ota.bin
Note:
- the OTA firmware file is included in this project under the firwmare folder.
- the server IP address must be set via the MAIN_OTA_URL macro from main.h file.
- Configure below code in the config main.h for AP to connect to.
* #define
MAIN_OTA_URL "http://192.168.0.137/winc1500_ota.bin"*
- Build the program and download it into the board.
- On the computer, open and configure a terminal application as the follows.
* Baud Rate : 115200
* Data : 8bit
* Parity bit : none
* Stop bit : 1bit
* Flow control : none
*
- Start the application.
- In the terminal window, the following text should appear:
* -- WINC1500 OTA firmware upgrade example --
* -- SAMXXX_XPLAINED_PRO --
* -- Compiled: xxx xx xxxx xx:xx:xx --
* Wi-Fi connected
* Wi-Fi IP is 192.168.0.10
* OTA Success. Press reset your board.
*
*
- In the second WINC1500 terminal window, the following text should appear:
* (1)Flash ID = c21320c2, Size = 4 MBit
* (1)Working Image offset = 0x3000 Rollback = 0x40000
* (2)(M2M)(Efuse) successfully loaded from bank 1.
* (2)EFUSE:MAC
* (2)(M2M)MAC_ADDR = F8:F0:05:20:AE:BF
* (3)NMI M2M SW VERSION 17.0
* (3)NMI MIN DRV VERSION 17.0
* (3)Built at Sep 23 2014 13:09:07
