"uboot_overlay_pru=AM335X-PRU-UIO-00A0.dtbo" was a recent change.. While you have U-boot: 2019.04, it's either: Jul 08 2019 or Aug 24 2020, so let's fix that.. sudo apt update sudo apt install bb-u-boot-am335x-evm Then: cd /opt/u-boot/bb-u-boot-am335x-evm/ sudo ./install.sh sudo reboot Then you should see the uio node here: UBOOT: Booted Device-Tree:[am335x-boneblack-uboot-univ.dts] UBOOT: Loaded Overlay:[AM335X-PRU-UIO-00A0] UBOOT: Loaded Overlay:[BB-ADC-00A0] UBOOT: Loaded Overlay:[BB-BONE-eMMC1-01-00A0] Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
