Hi, after I setup Wireless on my BBBW, I tried using the SPI interface using this simple Python code:
#import the library from Adafruit_BBIO.SPI import SPI spi = SPI(0,0) spi.writebytes(5) 1. When executed using sudo it runs without error. However, using a logic analyzer, I see no activity on either of the SPI pins (spi0 or spi1). I found the config-pin utility and tried using that to set the pins I need to spi. That command worked for the spi0 pins but returned an error (about univerala not being loaded) for spi1. Testing the spi0 pins that did respond to config-pin yielded no results. Finally, from an earlier conversation in this group, I followed these instructions (minus the eMMC steps) to address loading univerala: > > > https://github.com/RobertCNelson/linux-stable-rcn-ee/issues/1#issuecomment-296234338 > > After this I was able to run confi-pin on all spi pins. However when I ran my simple test python script, I saw no output on my logic analyzer and the command froze. I couldn't CTRL-C out of it and it would not die with a kill -9. Has anyone been able to use the SPI interfaces? I need to use both at the same time (one as a master, one as a slave) which is why I purchased the BBBW over other boards that only have one SPI interface. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
