SO Derrek's book is based on kernel 3.8.x where as you're now using a 4.x kernel. Chances are very likely you'll need to chance a few things in relation to SPI. NO hands on with SPI on the beaglebone yet personally. But first, you're going need to make sure your overlay file is correct for this kernel. Also, file pathing for hardware has changed too. So unless you've adjusted the code to work with this kernel, it likely will not work.
Can you show us the output of the lsmod command? First it would be good to make sure the SPIdev driver is actually loaded. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
