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].
30  
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].
