Taking photo using GR-LYCHEE through Pelion Device Management.
This firmware project works for GR-LYCHEE and GR-PEACH.
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.jsontombed_app.json
- Change the file name
- Wi-Fi
- Change the Wi-Fi setting in
mbed_app.json, i.e.nsapi.default-wifi-ssidandnsapi.default-wifi-password
- Change the Wi-Fi setting in
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 NetworkErrorappears 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.
