SPI on Dragonboard Debian


Is there any step by step information about how to enable an SPI connection to the Dragonboard on Debian Linaro? I found various parts on some messages but couldn’t clearly figure out how to handle it.


Please check https://github.com/96boards/documentation/blob/master/ConsumerEdition/DragonBoard-410c/Configuration/EnableSPI.md


Thanks but is there any way to enable SPI connections without flashing a new image on the board?


It might be possible to avoid reinstalling the rootfs, but there’s no way to avoid reflashing the boot partition.

If you are already running 16.06 LT version of Debian then things are easy, just skip the flash of the rootfs. If you are running an older version of the Debian then the instructions should mostly work but you must substitute the right version of the kernel throughout.
