Hi Robert, thank you very much for your prompt reply! Yesterday night I removed the line as you suggested me, and now I'm able to load my .dto files without any errors:
export SLOTS=/sys/devices/platform/bone_capemgr/slots export PINS=/sys/kernel/debug/pinctrl/44e10800.pinmux/pins sh -c "echo BB-SPI1-STD > $SLOTS" sh -c "echo DM-GPIO-Test > $SLOTS" sh -c "echo bone_pwm_P9_22 > $SLOTS" sh -c "echo am33xx_pwm > $SLOTS" The devices /dev/spidev2.x (btw, previously they were /dev/spidev1.x) are created and the DTO is loaded, but pins are not configured, according to /sys/kernel/debug/pinctrl/44e10800.pinmux/pins. Only DM-GPIO-Test (not in the Debian distribution whereas the other ones are all coming with the board) configures the pins. I'm wondering what am I supposed to do with this new Debian distribution, it seems a lot of things are changed. Thank you again!
