Flashing[edit]

Bootloader & Onboard Flash[edit]

  • A13 is now mainlined on U-boot
  • Caveat is that to run completely from the NAND Flash (MTD device), you need some patches
    • MTD device driver as well for using the onboard flash directly
  • VERY IMPORTANT info over here on how to do that: https://linux-sunxi.org/Installing_to_NAND
    • nand-part is used to build the descriptor. Remember to keep partitions for the chain loaders.
