That makes it even more confusing.. i was expecting '2' gpio nodes as that is usually the issue, but most of them show up..???... Do you happen to have a usb-serial adapter to plug into j1? https://elinux.org/Beagleboard:BeagleBone_Black_Serial I'd like to see what u-boot does on startup.. I'm most interested in this section: *********************************************** U-Boot 2019.04-00002-g07d5700e21 (Mar 06 2020 - 11:24:55 -0600), Build: jenkins-github_Bootloader-Builder-137 CPU : AM335X-GP rev 2.1 I2C: ready DRAM: 512 MiB No match for driver 'omap_hsmmc' No match for driver 'omap_hsmmc' Some drivers were not found Reset Source: Global warm SW reset has occurred.
