Hello,

I have been attempting to write C code for using SPI with the BBB. I am manipulating spidev (in my case spidev1.0) with ioctl() however I am unable to get SPI working. All of the libraries I have tried to use with a similar method also don't seem to work (e.g. https://github.com/deeplyembeddedWP/BeagleBone-SPI-Library, https://github.com/photomankc/BeagleBone-Black-Robot-Library/blob/master/motors/l6470.h). When I hook up the BBB SPI1 pins to the scope, there is no output.

I have disabled the HDMI boot overlays (audio and video) and enabled the SPI1 overlay. I am able to see signals on the scope with the Python Adafruit_BBIO.SPI library but with this method I have been unsuccessful. Is there something else to setup?

uname -r:

4.14.71-ti-r80

Thanks!

Please share your uEnv and code. An output of the console during boot would be helpful as well. I am struggling with the same problem on the Octavo Red development board (a PocketBeagle with more stuff). Oscilloscope hooked up to SPI_CS1. No pulses when doing a transfer and the signal is low...should be high with no activity. I don't believe the pins are mux'd correctly. Or, clocks are not being provided to the peripheral. I am used to working with QNX using register level operations to mux the pins, turn on the clocks and control the SPI bus. That works. Trying out Linux at the moment as an experiment.

For code, I was using the example Main.c from this library: https://github.com/deeplyembeddedWP/BeagleBone-SPI-Library/tree/master/Example
