39### Internal programming
40
41The SPI flash can be accessed using [flashrom].
42
43### External programming
44
45The easiest to flash externally is to simply extract the SPI flash from its socket.
46To do this gently take the SPI flash out of its socket and flash with your programmer.
47
48**NOTE: Don't forget to set the WP# AND HOLD# to 3V.**

50**NOTE2: Make sure to reinsert it in the right direction afterward**
