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

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