 Note that the Linux gpio mapping is not guaranteed to remain constant across kernel versions. Care should be taken to consult {{{/sys/kernel/debug/gpio}}} and {{{/sys/class/gpio}}} when changing kernel versions.

 When referring to [http://www.gateworks.com/usermanuals Gateworks board user hardware manuals] you will need to translate the hardware pin name to a gpio using the information above. Some examples:

  * Ventana GPIO![1]:DIO16 is GPIO block 1 IO 16 thus maps to gpio0 + 16 (or 0*32+16) = gpio-16
