When the pyboard boots up, it needs to choose a filesystem to boot from. If there is no SD card, then it uses the internal filesystem ``/flash`` as the boot filesystem, otherwise, it uses the SD card ``/sd``. +If needed, you can prevent the use of the SD card by creating an empty file +called ``/flash/SKIPSD``. If this file exists when the pyboard boots +up then the SD card will be skipped and the pyboard will always boot from the +internal filesystem (in this case the SD card won't be mounted but you can still +mount and use it later in your program using ``os.mount``). (Note that on older versions of the board, ``/flash`` is called ``0:/`` and ``/sd`` is called ``1:/``). |
