You need to install rkdeveloptool on your PC. Connect the board to your PC using a USB-C to USB-A cable. Before powering the board, press and hold the mask button, then plug in the power cable. Once this is done, your PC should detect the device, and you can verify it with: rkdeveloptool ld You can follow this guide: https://docs.armbian.com/User-Guide_Getting-Started/#rockchip

Please specify which OS and kernel version. By the way, I recommend building EDGE yourself.

moved Providing logs with armbianmonitor -u helps with troubleshooting and significantly raises chances that issue gets addressed.

I don't see anything above about your boot-loader being updated. i.e. u-boot or grub. If you're using u-boot, was your uInitrd in your /boot directory updated? The initrd-image needs to be converted to its u-boot format of uinitrd. Instructions for how to do that are located at the bottom of your boot.cmd file (using the mkimage command from the u-boot-tools package). Though that may be a generic example that you'll have to update for your system. Also if you have an armbianEnv.txt (or an equivalent) in your /boot directory, be sure it's up to date for your current kernel's devicetree file location and name. If that doesn't solve it read on.... I keep seeing everywhere that kernel 6.12 is broken. Not sure if that applies to all systems. I use the edge kernel (6.16) in my OrangePI-5-Plus. I've found that to work much better than Vendor (6.1). To chroot in from an another identical system. This works on Debian Trixie. I'm not sure about other OS's. Note: I don't know much about this, I recently found this from searching and used it myself. I found it works great to install new packages and also to run update-initramfs. mount -t proc proc /mnt/proc mount -t sysfs sysfs /mnt/sys mount -t devtmpfs devtmpfs /mnt/dev mount --bind /dev/pts /mnt/dev/pts # If you need for the chrooted system to be able to access the internet, the link at its: (/etc/resolv.conf) must be valid, so add this as well: mount --bind /run/systemd /mnt/run/systemd Then chroot in (I'm not sure if the /bin/bash) is necessary - or if you're using something else than bash, put that there instead?) chroot /mnt /bin/bash [Do what you need to do in there] i.e. install a different kernel, and be sure update-initramfs has been run or run it yourself, and the u-boot (or grub) is updated. Whenever you're installing a new kernel, it's a good idea to leave the old one there. Once you get it working, it might then be a good idea to remove any non-functioning kernels (like that 6.12), and leave any functioning kernels in. Then to back get out of chroot and return undo the above mounts: # Exit chroot exit # This line is only necessary if you mounted it to use the internet while chrooted: umount /mnt/run/systemd # Unmount the rest umount /mnt/dev/pts umount /mnt/dev umount /mnt/sys umount /mnt/proc umount /mnt

@Ian Coelho Success! I got it working by tweaking the eMMC parameters in the dtb file. Generally I changed the `<max-frequency>` to 50M. I've attached my version if you want to give it a shot, but make sure you have a backup ROM handy. my.dtb
