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
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.
