[beagleboard] [BeagleBoneAI]i use spidev1.0 or spidev1.0, but application can not communicate to spi slave for BeagleBoneAI
I am creating an application using /dev/spidev1.0 /dev/spidev1.1. However, the signals such as spi clcok, MISO, MOSI, and SPI_CS are not high/low, regardless of what is used. For the BeagleBone AI P9.28 -SPI3_SS1 P9.29 -SPI3_MISO P9.30 SPI3_MOSI P9.31 SPI3_SCK Why can't I do SPI communication with the slave? Of course, /dev/spidev1.0 and /dev/spi1.1 were created normally by configuring the devicetree. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
