I'm trying to enable SPI on my BBB but constantly fail following the advises I find in the forums.
It seems like echoing anything into /sys/devices/platform/bone_capemgr/slots is obsolete. Instead I should set up in /boot/uEnv.txt, but how? What should I add in that file? I've tried: cape_enable=bone_capemgr.enable_partno=BB-SPIDEV0 or: optargs=quiet drm.debug=7 capemgr.enable_partno=BB-SPI0-01 ...but I still don't get anything named spi* under /dev/ (yes, I've rebooted) ls -l /dev/spi* ls: cannot access '/dev/spi*': No such file or directory I would be happy with only one SPI, like SPI0 so I wouldn't have to bother with disabling HDMI. This is the state of my setup: sudo /opt/scripts/tools/version.sh git:/opt/scripts/:[ea6ea9fca05f36f5044398884375b0231348d6e2] eeprom:[A335BNLT000C1750BBBG0574] model:[TI_AM335x_BeagleBone_Black] dogtag:[BeagleBoard.org Debian Image 2018-01-28] bootloader:[eMMC-(default)]:[/dev/mmcblk1]:[U-Boot 2018.01-00002-g9aa111a004] kernel:[4.9.78-ti-r94] nodejs:[v6.12.3] uboot_overlay_options:[enable_uboot_overlays=1] uboot_overlay_options:[enable_uboot_cape_universal=1] pkg:[bb-cape-overlays]:[4.4.20180126.0-0rcnee0~stretch+20180126] pkg:[bb-wl18xx-firmware]:[1.20170829-0rcnee2~stretch+20180104] pkg:[firmware-ti-connectivity]:[20170823-1rcnee0~stretch+20170830] groups:[debian : debian adm kmem dialout cdrom floppy audio dip video plugdev users systemd-journal i2c bluetooth netdev cloud9ide gpio pwm eqep admin spi tisdk weston-launch xenomai] dmesg | grep pinctrl-single [ 1.380806] pinctrl-single 44e10800.pinmux: 142 pins at pa f9e10800 size 568 END Anyone out there, who knows what to do? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
