Welcome to the pielectricseagles-usb-update-desktop wiki!

Prerequisite:

  • USB stick with FAT32 format
  • Any software of receiving checksum of file
  • Having files for our drone application
  • Any text editor

To do:

  1. Create folder encrypted_update
  2. Open folder encrypted_update and create folder update in inside encrypted_update directory
  3. Copy your files to encrypted_update/update directory
  4. Add/Copy your three different scripts to encrypted_update directory (should be before installation, after installation and during installation scripts)
  5. Add your JSON file update.json in encrypted_update directory. You must correct copy/paste checksum after getting checksum file via software. Write each filename and destination path to install each file. You must exact name files that matches name of files in encrypted_update/update directory
  6. Compress the folder encrypted_update with password. This compressed folder must be named encrypted_update.7z. Please record your password, because you will add this password to JSON file start_update.json according instruction.
  7. Add your JSON file start_update.json outside nearest encrypted_update directory.
  8. Copy two files of start_update.json and encrypted_update.7z to USB drive

Required scripts:

This script should show like (FOR update.json)

{
  "update": [
    {
      "location_file": "config.ini",
      "checksum": "1bc8083fe988bf49f998ac548276987e49488677",
      "version": "1.0.0",
      "install_path": "/etc/pielectricseagles/config"
    },
    {
      "location_file": "pielectricseagles",
      "checksum": "9acdd06040c744a731fa25a22ccee3b801ab8a38",
      "version": "1.0.1",
      "install_path": "/usr/bin/pielectricseagles"
    }
  ]
}

Where:

"location_file" is location filename for directory encrypted_update/update

"checksum" is checksum files for directory encrypted_update/update

"version" is setting version

"install_path" is destination path to install this file to Raspberry Pi Zero device

This script should show like (FOR start_update.json)

{
	"update": {
		"file_name": "encrypted_update.zip",
		"checksum": "ef83d6fd532561bbb4bae070fdfb5f64ea813ecb",
		"vendor_id": "0781",
		"product_id": "5567"
	}
}

Where:

"file_name" is name of file compressed 7z folder (usually we write: "encrypted_update.7z")

"checksum" is checksum of encrypted_update.7z

"vendor_id" is first of four character password of compress 7z folder (e.g. 1234)

"product_id" is fifth of four character password of compress 7z folder (e.g. 5678)
