# Unduh, buat, flash, dan jalankan demo FreerTOS OTA di Microchip Curiosity MZEF PIC32
**penting**
Integrasi referensi ini di-host di repositori Amazon-Freertos yang tidak digunakan lagi. Kami menyarankan Anda [mulai di sini](freertos-getting-started-modular.md) ketika Anda membuat proyek baru. Jika Anda sudah memiliki proyek FreeRTOS yang sudah ada berdasarkan repositori Amazon-Freertos yang sekarang tidak digunakan lagi, lihat. [Panduan Migrasi Repositori Github Amazon-freertos](github-repo-migration.md)
**catatan**
Sesuai dengan Microchip, kami menghapus Curiosity PIC32 MZEF () DM320104 dari cabang utama repositori Freertos Reference Integration dan tidak akan lagi membawanya dalam rilis baru. Microchip telah mengeluarkan [pemberitahuan resmi](https://www.microchip.com/DevelopmentTools/ProductDetails/PartNO/DM320104) bahwa PIC32 MZEF (DM320104) tidak lagi direkomendasikan untuk desain baru. Proyek PIC32 MZEF dan kode sumber masih dapat diakses melalui tag rilis sebelumnya. Microchip merekomendasikan agar pelanggan menggunakan [papan Pengembangan Curiosity PIC32 MZ-EF-2.0 ()](https://devices.amazonaws.com/detail/a3G0h0000077I69EAE/Curiosity-PIC32MZ-EF-2-0-Development-Board) untuk desain baru. DM320209 PIC32MZv1 Platform ini masih dapat ditemukan di [v202012.00 dari repositori Integrasi Referensi](https://github.com/aws/amazon-freertos/tree/202012.00) FreeRTOS. Namun, platform ini tidak lagi didukung oleh Referensi FreeRTOS [v202107.00](https://github.com/aws/amazon-freertos/tree/202107.00).
**Untuk mengunduh kode demo FreeRTOS OTA**
+ Anda dapat mengunduh kode sumber di GitHub situs di [https://github.com/FreeRTOS/FreeRTOS](https://github.com/FreeRTOS/FreeRTOS).
**Untuk membangun aplikasi demo pembaruan OTA**
1. Ikuti petunjuk [Memulai dengan FreeRTOS](freertos-getting-started.md) untuk mengimpor `aws_demos` proyek ke MPLAB X IDE, konfigurasikan AWS IoT titik akhir Anda, SSID Wi-Fi dan kata sandi Anda, serta kunci pribadi dan sertifikat untuk papan Anda.
1. Buka `vendors/vendor/boards/board/aws_demos/config_files/ota_demo_config.h` file, dan masukkan sertifikat Anda.
```
[] = "your-certificate-key";
```
1. Tempel konten sertifikat penandatanganan kode Anda di sini:
```
#define otapalconfigCODE_SIGNING_CERTIFICATE [] = "your-certificate-key";
```
Ikuti format yang sama dengan `aws_clientcredential_keys.h` -- setiap baris harus diakhiri dengan karakter baris baru ('\$1n') dan diapit tanda kutip.
Misalnya, sertifikat Anda akan terlihat mirip dengan yang berikut ini:
```
"-----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";
```
1. Instal [Python 3](https://www.python.org/downloads/) atau yang lebih baru.
1. Instal `pyOpenSSL` dengan menjalankan`pip install pyopenssl`.
1. Salin sertifikat penandatanganan kode Anda dalam format.pem di jalur. `demos/ota/bootloader/utility/codesigner_cert_utility/` Ganti nama file `aws_ota_codesigner_certificate.pem` sertifikat.
1. Buka`freertos/vendors/vendor/boards/board/aws_demos/config_files/aws_demo_config.h`, beri komentar`#define CONFIG_CORE_MQTT_MUTUAL_AUTH_DEMO_ENABLED`, dan tentukan `CONFIG_OTA_MQTT_UPDATE_DEMO_ENABLED` atau`CONFIG_OTA_HTTP_UPDATE_DEMO_ENABLED`.
1. Bangun solusinya dan pastikan itu dibangun tanpa kesalahan.
1. Mulai emulator terminal dan gunakan pengaturan berikut untuk terhubung ke papan Anda:
+ Tingkat baud: 115200
+ Bit data: 8
+ Paritas: Tidak ada
+ Hentikan bit: 1
1. Cabut debugger dari papan Anda dan jalankan proyek di papan Anda untuk mengonfirmasi bahwa debugger dapat terhubung ke Wi-Fi dan broker pesan AWS IoT MQTT.
Ketika Anda menjalankan proyek, MPLAB X IDE harus membuka jendela output. Pastikan **ICD4**tab dipilih. Anda akan melihat output berikut.

Output ini menunjukkan Microchip Curiosity PIC32 MZEF dapat terhubung AWS IoT dan berlangganan topik MQTT yang diperlukan untuk pembaruan OTA. `Missing job parameter`Pesan diharapkan karena tidak ada pekerjaan pembaruan OTA yang tertunda.
