The Raspberry family of cards such as NanoPi M3 and Pine64, all have the same single compatible format for GPIO:s within its 40-pin header.
The DragonBoard 410C and also the "INFORCE 6410PLUS" (which is the only card delivering the SnapDragon 600 that I'm aware of) also have 40-pin headers.
What is the digital GPIO mapping on these, are they "RaspBerry Pi compatible" also??
Any reference to your header-to-GPIO pin mapping scheme would be appreciated.
Also in all cases does the DragonBoard 410C and also the "INFORCE 6410PLUS" have the same GPIO header PIN mapping?
(Also, where can I read about what Mhz update frequency the SnapDragon will deliver for the GPIO pins, and how to do GPIO input/output in low-level C programming, e.g. what the memory mappings to the GPIO registers are?)
Kindly let me know, thanks!
