I fired up a Pocket Beagle today with the 2018-10-28 image and notice /dev/i2c-1 is missing.
Here's what dmesg says: bone $ *dmesg -H | grep i2c* [ +0.000852] omap_i2c 44e0b000.i2c: could not find pctldev for node /ocp/l4_wkup@44c00000/scm@210000/pinmux@800/pinmux_i2c0_pins, deferring probe [ +0.000063] omap_i2c 4802a000.i2c: could not find pctldev for node /ocp/l4_wkup@44c00000/scm@210000/pinmux@800/pinmux_bb_i2c1_pins, deferring probe [ +0.000937] omap_i2c 4819c000.i2c: bus 2 rev0.11 at 400 kHz [ +0.001268] i2c /dev entries driver [ +0.007484] input: tps65217_pwr_but as /devices/platform/ocp/44e0b000.i2c/i2c-0/0-0024/tps65217-pwrbutton/input/input0 [ +0.000108] omap_i2c 44e0b000.i2c: bus 0 rev0.11 at 400 kHz [ +0.000759] pinctrl-single 44e10800.pinmux: pin PIN97 already requested by ocp:P2_09_pinmux; cannot claim for 4802a000.i2c [ +0.011333] pinctrl-single 44e10800.pinmux: pin-97 (4802a000.i2c) status -22 [ +0.007129] pinctrl-single 44e10800.pinmux: could not request pin 97 (PIN97) from group pinmux_bb_i2c1_pins on device pinctrl-single [ +0.012083] omap_i2c 4802a000.i2c: Error applying setting, reverse things back [ +0.007347] omap_i2c: probe of 4802a000.i2c failed with error -22 And bone$ *sudo /opt/scripts/tools/version.sh* git:/opt/scripts/:[e9bcff232834702c1c810710706ee815d77b080b] eeprom:[A335PBGL00A21750EPB02572] model:[TI_AM335x_PocketBeagle] dogtag:[BeagleBoard.org Debian Image 2018-10-28] bootloader:[microSD]:[/dev/mmcblk0]:[U-Boot 2018.09-00002-gd5b4c4b656]:[location: dd MBR] kernel:[4.14.71-ti-r81] nodejs:[v6.14.4] uboot_overlay_options:[enable_uboot_overlays=1] uboot_overlay_options:[uboot_overlay_addr4=/lib/firmware/BB-I2C1A-FAST-00A0.dtbo] uboot_overlay_options:[disable_uboot_overlay_video=1] uboot_overlay_options:[uboot_overlay_pru=/lib/firmware/AM335X-PRU-RPROC-4-14-TI-00A0.dtbo] uboot_overlay_options:[enable_uboot_cape_universal=1] pkg check: to individually upgrade run: [sudo apt install --only-upgrade <pkg>] pkg:[bb-cape-overlays]:[4.4.20181019.0-0rcnee0~stretch+20181019] pkg:[bb-wl18xx-firmware]:[1.20180517-0rcnee0~stretch+20180517] pkg:[kmod]:[23-2rcnee1~stretch+20171005] pkg:[librobotcontrol]:[1.0.3-git20181009.0-0rcnee0~stretch+20181010] pkg:[firmware-ti-connectivity]:[20170823-1rcnee1~stretch+20180328] 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] cmdline:[console=ttyO0,115200n8 bone_capemgr.uboot_capemgr_enabled=1 root=/dev/mmcblk0p1 ro rootfstype=ext4 rootwait coherent_pool=1M net.ifnames=0 quiet] dmesg | grep pinctrl-single [ 1.106310] pinctrl-single 44e10800.pinmux: 142 pins at pa f9e10800 size 568 [ 1.381858] pinctrl-single 44e10800.pinmux: pin PIN97 already requested by ocp:P2_09_pinmux; cannot claim for 4802a000.i2c [ 1.393191] pinctrl-single 44e10800.pinmux: pin-97 (4802a000.i2c) status -22 [ 1.400320] pinctrl-single 44e10800.pinmux: could not request pin 97 (PIN97) from group pinmux_bb_i2c1_pins on device pinctrl-single dmesg | grep gpio-of-helper [ 1.114738] gpio-of-helper ocp:cape-universal: ready END What's up? --Mark p.s.
