I've seen from a previous post that it is possible to get SPI working on the Dragonboard 410c.However this seems like a lot of work just to enable something that the spec says should be on the 40 Pin Low Speed Expansion Connector anyway.
Are there plans to have SPI on by default as per the spec? Or at least an easier way to switch SPI on?
Yes, it is pain that SPI is not working as a default on DragenBoard 410C.
We are planning to enable SPI in the next release but I do not have the concrete detail information yet.I will write on the forum when I have the information.
Things have improved some and the SPIDEV bits are now included in the image. Here is a howto to get this going.
