Steps to build this firmware with Mbed CLI

Import project

$ mbed import http://os.mbed.com/users/coisme/code/Pelion-GR-LYCHEE-camera-firmware/

Setting

Ethernet (GR-PEACH only)
- Change the file name mbed_app.RZ_A1H_Ethernet.json to mbed_app.json
Wi-Fi
- Change the Wi-Fi setting in mbed_app.json, i.e. nsapi.default-wifi-ssid and nsapi.default-wifi-password

If you haven't set your Pelion API key, run the following command.

$ mbed config -G CLOUD_SDK_API_KEY <API_KEY>

Setting for Pelion Device Management

$ mbed dm init -d "example.com" --model-name "PELION_DEMO" -q --force

Compile

For GR-LYCHEE:

$ mbed compile -t GCC_ARM -m GR_LYCHEE

For GR-PEACH:

$ mbed compile -t GCC_ARM -m RZ_A1H

Write the created .bin file to your GR-LYCHEE/PEACH.

That's it! :-)

LED Status Indicator

LEDs next to UB0 show the status of your GR-LYCHEE/PEACH.

LED#	GR-LYCHEE	GR-PEACH	Status	Description
LED1	green	red	Normal	Turned on after the device is registered to Pelion Device Management successfully.
LED2	yellow	green	Error	Turned on when the network initialization failed. Check your Wi-Fi setting.
LED3	orange	blue	Error	Turned on when the Pelion Device Management Client initialization failed. Check your SD card.
LED4	red	red	Error	Turned on when the network is disconnected. Check your Wi-Fi network status.

Clear device identity

If you want to clear the device's identity, connect to the device via serial terminal. Then input r command. The device flushes the identity storage, then reboot.

Known Issues

client_error(6) -> Client in reconnection mode NetworkError appears when connecting to network, but eventually connection will be established.
Warning message "MBEDTLS_TEST_NULL_ENTROPY has been enabled. This configuration is not secure and is not suitable for production use" appears when compiling the project for GR-PEACH. This can be ignored in development stage.
