Hi, I've installed debian + kernal 4.19-ti-rt on my BBB according to this instruction: https://www.digikey.com/eewiki/display/linuxonarm/BeagleBone+Black
After I finally started the system I'm trying now to change pins roles to start using PRU. When I change /boot/uEnv.txt file to enable overlays and select which one to use, it doesn't seem to work at all - after reboot pins' roles remain default, no PRU pins enabled. What am I doing wrong? /opt/scripts/tools/version.sh git:/opt/scripts/:[15198b3b7ff40ef517a305eeb7cd20e57f18d37a] eeprom:[A335BNLTEIA05115BBBK0079] model:[TI_AM335x_BeagleBone_Black] bootloader:[eMMC-(default)]:[/dev/mmcblk1]:[U-Boot 2019.04-dirty]:[location: dd MBR] kernel:[4.19.31-ti-rt-r19] uboot_overlay_options:[enable_uboot_overlays=1] uboot_overlay_options:[disable_uboot_overlay_video=1] uboot_overlay_options:[uboot_overlay_pru=/lib/firmware/AM335X-PRU-RPROC-4-19 -TI-00A0.dtbo] pkg check: to individually upgrade run: [sudo apt install --only-upgrade <pkg>] pkg:[bb-cape-overlays]:[4.4.20190610.0-0rcnee0~stretch+20190610] WARNING:pkg:[bb-wl18xx-firmware]:[NOT_INSTALLED] pkg:[kmod]:[23-2rcnee1~stretch+20171005] WARNING:pkg:[librobotcontrol]:[NOT_INSTALLED] pkg:[firmware-ti-connectivity]:[20180825+dfsg-1rcnee1~stretch+20181217] groups:[debian : debian adm kmem dialout cdrom floppy audio dip video plugdev users systemd-journal i2c netdev gpio pwm eqep bluetooth admin spi tisdk weston-launch xenomai cloud9ide] cmdline:[console=ttyO0,115200n8 root=UUID=702af096-c19d-4ce1-ac79- 0ad255340345 ro rootfstype=ext4 rootwait] dmesg | grep remote [ 2.715739] remoteproc remoteproc0: wkup_m3 is available [ 2.717172] remoteproc remoteproc1: 4a334000.pru is available [ 2.717809] remoteproc remoteproc2: 4a338000.pru is available [ 3.051770] remoteproc remoteproc0: powering up wkup_m3 [ 3.109595] remoteproc remoteproc0: Booting fw image am335x-pm-firmware. elf, size 217168 [ 3.122818] remoteproc remoteproc0: remote processor wkup_m3 is now up dmesg | grep pru [ 2.717172] remoteproc remoteproc1: 4a334000.pru is available [ 2.717362] pru-rproc 4a334000.pru: PRU rproc node pru@4a334000 probed successfully [ 2.717809] remoteproc remoteproc2: 4a338000.pru is available [ 2.718000] pru-rproc 4a338000.pru: PRU rproc node pru@4a338000 probed successfully dmesg | grep pinctrl-single [ 1.229997] pinctrl-single 44e10800.pinmux: 142 pins, size 568 dmesg | grep gpio-of-helper [ 1.232540] gpio-of-helper ocp:cape-universal: ready lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub END /boot/uEnv.txt uname_r=4.19.31-ti-rt-r19 uuid=702af096-c19d-4ce1-ac79-0ad255340345 enable_uboot_overlays=1 disable_uboot_overlay_video=1 uboot_overlay_pru=/lib/firmware/AM335X-PRU-RPROC-4-19-TI-00A0.dtbo Cheers -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
