Descarga, compilación, instalación y ejecución de la demostración de OTA de FreeRTOS en Microchip Curiosity PIC32MZEF
importante
Esta integración de referencia está alojada en el repositorio de Amazon-FreeRTOS, que está en desuso. Recomendamos empezar por aquí al crear un nuevo proyecto. Si ya tiene un proyecto FreeRTOS existente basado en el repositorio Amazon FreeRTOS, ahora obsoleto, consulte Guía de migración del repositorio Github de Amazon-FreeRTOS.
nota
De acuerdo con Microchip, eliminaremos Curiosity PIC32MZEF (DM320104) de la rama principal del repositorio de integración de referencias de FreeRTOS y ya no lo incluiremos en las nuevas versiones. Microchip ha publicado un aviso oficial
Para descargar el código de demostración de OTA de FreeRTOS
-
Puede descargar el código fuente desde el sitio de GitHub en https://github.com/FreeRTOS/FreeRTOS
.
Para compilar la aplicación de demostración de actualización OTA
-
Siga las instrucciones de Introducción a FreeRTOS para importar el proyecto
aws_demosa MPLAB X IDE, configure el punto de enlace de AWS IoT el SSID y contraseña wifi y un certificado y clave privada para la placa. -
Abra el archivo
vendors/e introduzca su certificado.vendor/boards/board/aws_demos/config_files/ota_demo_config.h[] = "your-certificate-key"; -
Pegue el contenido de su certificado de firma de código aquí:
#define otapalconfigCODE_SIGNING_CERTIFICATE [] = "your-certificate-key";Siguiendo el mismo formato que
aws_clientcredential_keys.h--, cada línea debe acabar con el carácter de línea nueva ('\n') y estar entrecomillado.Por ejemplo, el certificado debe tener un aspecto similar al siguiente:
"-----BEGIN CERTIFICATE-----\n" "MIIBXTCCAQOgAwIBAgIJAM4DeybZcTwKMAoGCCqGSM49BAMCMCExHzAdBgNVBAMM\n" "FnRlc3Rf62lnbmVyQGFtYXpvbi5jb20wHhcNMTcxMTAzMTkxODM1WhcNMTgxMTAz\n" "MTkxODM2WjAhMR8wHQYDVQBBZZZ0ZXN0X3NpZ25lckBhbWF6b24uY29tMFkwEwYH\n" "KoZIzj0CAQYIKoZIzj0DAQcDQgAERavZfvwL1X+E4dIF7dbkVMUn4IrJ1CAsFkc8\n" "gZxPzn683H40XMKltDZPEwr9ng78w9+QYQg7ygnr2stz8yhh06MkMCIwCwYDVR0P\n" "BAQDAgeAMBMGA1UdJQQMMAoGCCsGAQUFBwMDMAoGCCqGSM49BAMCA0gAMEUCIF0R\n" "r5cb7rEUNtWOvGd05MacrgOABfSoVYvBOK9fP63WAqt5h3BaS123coKSGg84twlq\n" "TkO/pV/xEmyZmZdV+HxV/OM=\n" "-----END CERTIFICATE-----\n"; -
Instale Python 3
o superior. -
Instale
pyOpenSSLejecutandopip install pyopenssl. -
Copie el certificado de firma de código en formato .pem en la ruta
demos/ota/bootloader/utility/codesigner_cert_utility/. Cambie el nombre del archivo del certificado aaws_ota_codesigner_certificate.pem. -

Compile la solución y asegúrese de que se compila sin errores.
-
Inicie un emulador de terminal y utilice los siguientes ajustes para conectarse a la placa:
-
Velocidad en baudios: 115 200
-
Bits de datos: 8
-
Paridad: ninguna
-
Bits de parada: 1
-
-
Desconecte el depurador de la placa y ejecute el proyecto en la placa para confirmar que puede conectarse al wifi y al agente de mensajes MQTT de AWS IoT.
Cuando ejecuta el proyecto, MPLAB X IDE debe abrir una ventana de salida. Asegúrese de que la pestaña ICD4 está seleccionada. Debería ver los siguientes datos de salida.
