What kernel version are using? Have you load the overlay 'BB-SPIDEV0' to the cape manager? You should see something like /dev/spidev*.* after the SPI is enable. If you are using kernel version larger than 4.4, then you just configure the pin to spi mode using 'sudo config-pin PIN_NUMBER spi', for do, di, cs and sclk.
For a lower kernel version, just load the related overlay under /lib/firmware/ 在 2017年5月5日星期五 UTC+2下午2:54:16，[email protected]写道： > > > Hi Rafael and jacek, > > Will you both please explain me the procedure how you both have used SPI > API. i am newbie to BBB so i won't able to understand how can i implement > SPI on BBB. > > Please reply me as soon as possible. > > Thanks and regards > Rohit > -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
