I have the same problem as this user: https://groups.google.com/forum/#!category-topic/beagleboard/pru/g2NcW2sUX-4 in that remoteproc only detects the wkup_m3 coprocessor (whatever that is) and doesn't seem to detect the PRUs on boot.
This is a fresh install of Sretch IOT from beagleboard.org, with the kernel and cape-overlays updated through the tools/scripts... version.sh shows: git:/opt/scripts/:[c2a5ae96746d10d711c60bc84ba244f4cd7b75c3] eeprom:[A335BNLT00C03816BBBK190D] model:[TI_AM335x_BeagleBone_Black] dogtag:[BeagleBoard.org Debian Image 2018-10-07] bootloader:[microSD-(push-button)]:[/dev/mmcblk0]:[U-Boot 2018.09-00002-g0b54a51eee]:[location: dd MBR] kernel:[4.14.108-ti-r104] nodejs:[v6.14.4] uboot_overlay_options:[enable_uboot_overlays=1] uboot_overlay_options:[disable_uboot_overlay_emmc=1] uboot_overlay_options:[disable_uboot_overlay_video=1] uboot_overlay_options:[disable_uboot_overlay_audio=1] uboot_overlay_options:[disable_uboot_overlay_wireless=1] uboot_overlay_options:[disable_uboot_overlay_adc=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]:[4.4.20190429.0-0rcnee0~stretch+20190429] pkg:[bb-wl18xx-firmware]:[1.20180517-0rcnee0~stretch+20180517] pkg:[kmod]:[23-2rcnee1~stretch+20171005] pkg:[librobotcontrol]:[1.0.3-git20181005.0-0rcnee0~stretch+20181005] 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 remote [ 1.302485] remoteproc remoteproc0: wkup_m3 is available [ 1.389525] remoteproc remoteproc0: powering up wkup_m3 [ 1.389661] remoteproc remoteproc0: Booting fw image am335x-pm-firmware.elf, size 217168 [ 1.393097] remoteproc remoteproc0: remote processor wkup_m3 is now up dmesg | grep pru dmesg | grep pinctrl-single [ 0.971911] pinctrl-single 44e10800.pinmux: 142 pins at pa f9e10800 size 568 dmesg | grep gpio-of-helper [ 0.984114] gpio-of-helper ocp:cape-universal: ready lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub END What am I doing wrong here? Surely PRU support is one of those things that should be working out of the box with the correct u-boot overlay applied? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
