I'm using the IoT image I downloaded off intel website. The /etc/verion is 201502260041 . I'm not sure there is
any specific spidev library, the module is part of linux. Isn't it? I just did a gcc of spitest.c (without having any
additional -l option like I had to with mraa library).
I apologize for the late reply. I’ve been testing with the same guide and I also get the same results as you. I don’t have a Debian image available at the moment, so I’m not able to test it using Wheezy. However, I found this thread about SPI and I think you’ll find it useful https://communities.intel.com/thread/55920.
