Online external images usage

  • updated: Fri 26 May 2023 01:47:31 PM CST WIP:
  • At this moment testing images not visible inside Wizard need to use force to show all files via write into eMMC …
  • Need to try to improve OOWOW image logic! original images slow check and show warnings, and don't have meta information WIP:
  • Need to share this information with images developers for making better results
  • Test repack image with xze - OK
  • Test redirect usage to dl again with xze - OK

Image oowow compatible requirements

We recommend using zxe feature for image developers, to provide better service for users like as:

  • Provide additional information about images
  • Its fully compatible with the common xz format, and same possible to use anywhere
  • Fast-checking image integrity before writing it
  • Make warranty its image will be suitable for current board installation
  • Fast optimal compression for fastest decompression on SBC
  • Image signup
  • etc…

Sure all requirements are optional, but why not follow them by other developers, because its images will be created especially for our devices

WIP:
