I can't seem to get #NetBSD 11 booting on the #BeagleBoneBlack from EMMC. I downloaded the https://armbsd.org image, wrote to SD, booted from SD, ran sysinst... But on reboot I just get "CCCCCCCC" meaning there's no bootloader. Boot from SD works but of course that only gets me back in the live installer. What do I do?
