SD Card Flash Utility

• Etcher (GitHub) an Electron app.
  Creates filesystem and copies (OS) image file (.img), byte-for-byte, onto target media.

  • If USB stick, the burned filesystem is oddly accessible at both Win-10 and TV-box.
    Win-10 reports filesystem as FAT, and can r/w, but also prompts to format it.
    If SD card, the burned filesystem is entirely inaccessible at Win-10.

Firmware Mod Utilities

Firmware Mod Methods

   • Perform image mods, optionally, prior to burning.
   • Bootloader must be setup to handle OS selection;
     external (SD/USB) vs. internal (eMMC/NAND).

2. Flash image using device's internal pre-boot menu.
   With source image file (.img) copied to an SD card or USB stick.
