Hello guys, I am a beginner in SPI. For Beaglebone blue, do I need to enable any kind of SPI configuration? When I run rc_spi_loopback, I get the following error irrespective of the spi device connected or not. ubuntu@arm:~$ rc_spi_loopback ERROR: pru-rproc driver missing Testing SPI
Sending 11 bytes: Hello World Received 11 bytes: Sending byte: 0x42 Received: 0x0 The wrong data was received but no errors detected Likely the MISO and MOSI lines are not connected with a loopback jumper which is necessary for this test. Exiting Cleanly And one more issue, While the device is connected, dmesg shows unable to select pin group error. I tried to install spi tools from https://github.com/cpb-/spi-tools And using spi-config -d /dev/spidev1.0 -q gives spiready=0 irrespective of device connected or not.. I think, I am missing some beginning step for SPI configuration. Any kind of help is appreciated.
