  16 ## Flashing coreboot
  17
  18 ### Internal programming
  19
  20 The main SPI flash can be accessed using [flashrom].
  21
  22 ### External programming
  23
  24 The system has an internal flash chip which is a 8 MiB soldered SOIC-8 chip.
  25 This chip is located on the top middle side of the board. It's located
  26 between SoC and Q7 connector. Use clip (or solder wires) to program
  27 the chip.
  28 Specifically, it's a Winbond W25Q64FW (1.8V), whose datasheet can be found
  29 [here][W25Q64FW].

  31 The system has an external flash chip which is a 8 MiB soldered SOIC-8 chip.
  32 This chip is located in the middle of carrier board close to the flex cable
  33 connection.
  34 Specifically, it's a Winbond W25Q64FV (3.3V), whose datasheet can be found
  35 [here][W25Q64FV].
