INSTALL NOTES - READ

Platform Installation

Install VS Code + PlatformIO

PlatformIO - Home - Platforms - Advanced Installation

Paste link: https://github.com/Wiz-IO/platform-azure

SDK 19.10/11 workaroud

Fast Uninstal

goto C:\Users\USER_NAME.platformio\platforms

• delete folder azure ( builders )
• delete folder framework-azure ( sources )
• delete folder tool-azure ( azsphere )
• delete folder toolchain-arm-poky-linux-musleabi-hf (compiler )

New Project - PlatformIO

PlatformIO - Home - New

• enter Project Name - Board write-search 'azure' - Select Linux or Arduino
• you will have basic template project
• Open 'src/app_manifest.json' and enter your 'Capabilities'
• Open 'platformio.ini' and edit your settings
• Project platformio.ini example:

[env:avnet_aesms_mt3620]
platform = azure
board = avnet_aesms_mt3620
framework = arduino
monitor_port = COM6
monitor_speed = 115200

;board_build.sdk = C:/Program Files (x86)/Microsoft Azure Sphere SDK ; path to ...
;board_build.sysroot = 2+Beta1806  ; default is max version, 3+Beta1909
;board_build.delete = all ; default is all applications, or = current 

;board_build.copy =  filename.1 filename.2 
;    copy files from project SRC to image-package, as certificates, settings, etc
;    path is /mnt/APP-GUID/filename ... Storage_GetAbsolutePathInImagePackage()

;board_build.ex_mode = enable ; empty key: disabled ; experimental mode for libc, libwolfssl...
;board_build.verbose = enable ; verbose for azsphere 

;build_flags = -D ANY_FLAG

platform-azure's Issues

Setup Clarity

H Wiz,

Am just curious on following items.

1. Does the Azure Sphere is re-flashed with custom software
2. How Aurdino is used along with the base Sphere board
3. Does the security still valid as given by MSFT

azureiot: missing cstring

platformio.ini

[env:avnet_aesms_mt3620]
platform = azure
board = avnet_aesms_mt3620
framework = arduino

main.cpp

#include <Arduino.h>
#include <azureiot/iothub_device_client_ll.h>

void setup() {
  // put your setup code here, to run once:
}

void loop() {
  // put your main code here, to run repeatedly:
}

Communicate M4 & M7 issues

I am trying to communicate M4 and M7 cores, and I find 2 issues:

• The component ID change everytime the code is uploaded to the board, and the number it is not the same as the one in componentID from app_manifest.json.
• Everytime I upload a new application it removes all the applications installed in the board. I use Visual Code to upload different components .

NEW APPLICATION IS READY**

No COM6

My Azure Sphere shows only 3 COM ports (COM5, COM7, COM8). Please help me figure out how to get COM6.

Serial.printf has no effect

Host: Windows 10 Home, PIO Core 4.0.2, platform-azure c6b6adf
Device: AES-MS-MT3620-SK-G
Program: ArduinoAzureBlink example

Expected: platformio.exe device monitor should display serial messages such as "Arduino - Hello World - PlatformIO" and "Loop".
Actual: device monitor shows "[PLUTON] Booting application core" from bootloader, no more message after that

I also tried changing Serial.printf to Log_Debug, but it has the same result.
