Did a fast search on Google for u-boot Does u-boot need to be compiled or are binaries available for armbian?

OK so after I've connected successfully and ran the upgrade for kernel, what do you know, the OS booted :)) Anyway, managed to log it and here's a diff of boot from before and after the upgrade https://www.diffchecker.com/ER6op67Q/ What I can tell is that some addresses for memory I think, seem to have changed Anyway, thanks a lot guys for helping and eventually fixing the issue, even if I don't know what changed Hopefully will continue to work fine for the foreseeable future

So am trying here to provide more info. Friend of mine borrowed me a usb to serial adapter, but clueless on what to do. On Windows I know about Putty, but would like to do it on Ubuntu. Below is my hardware, so please let me know how I can provide more info (what wire goes where) !?

in my case last bootable is 6.12.17

Nothing happens on holding or taping space bar while booting At least nothing on screen Unfortunately don't have a adapter to check thing on serial

Personally not skilled enough to do it, but if no additional hardware needed for it, and let me know how to do it, I'll do it

In my case, armbian 25.5.0-trunk.256 still no go same thing happens not able to boot - rock pi 4b

for now I've stopped kernel upgrades sudo apt-mark hold linux-image-current-rockchip64 linux-dtb-current-rockchip64 linux-u-boot-rockpi-4b-current can resume with sudo apt-mark unhold linux-image-current-rockchip64 linux-dtb-current-rockchip64 linux-u-boot-rockpi-4b-current did this since the option to disable armbian kernel upgrades in armbian-config is not working in my case for some reason

@Torgar had the chance to check 6.12.19 ? possible change fix ? https://web.git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-6.12.y&id=39e4a0b613bd4d577321b207bb333f6213e8af6b sudo apt show linux-image-current-rockchip64 Package: linux-image-current-rockchip64 Version: 25.5.0-trunk.230 Priority: optional Section: kernel Source: linux-6.12.19 Maintainer: Armbian Linux <info@armbian.com> Installed-Size: 277 MB Provides: linux-image, linux-image-armbian, armbian-current Armbian-Kernel-Version: 6.12.19 Armbian-Kernel-Version-Family: 6.12.19-current-rockchip64 Armbian-Original-Hash: 6.12.19-Se9cc-Da873-Pfa20-C1f18H02eb-HK01ba-Vc222-B9bbb-R448a Download-Size: 48.6 MB APT-Sources: https://beta.armbian.com bookworm/main arm64 Packages Description: Armbian Linux current kernel image 6.12.19-current-rockchip64 This package contains the Linux kernel, modules and corresponding other files. version "6.12.19" git revision "e9cc806c0152fa9993f817cebf42989a3e2530bb" codename "Baby Opossum Posse" drivers hash "a873450a_3865dc87" patches hash "fa2093d7b29c5de9" .config hash "1f18a394d4cddb05" .config hook hash "02eb6b2bfb4dca2a" variables hash "c22207b66dc5dd57157df2cd7b9c20559b2ed8ac44b9c3c3b9704002c06b8921" framework bash hash "9bbbd4b74c282bc5"

Hello guys Been using Armbian on my RockPi 4b as a media server for few months now and took every update up until the latest 25.5.0-trunk.185 Now this was made with apt upgrade command and after I reboot, system no longer boots at all, freezing on initial boot stage. No HDMI sign at all also. If I plug an old armbian that I have on sdcard, I see U-Boot screen for few seconds, then reboots (basically bootloop). OS was installed to internal eMMC. Downgraded back to Armbian_community_25.5.0-trunk.131_Rockpi-4b_bookworm_current_6.12.16_minimal from github and all is running fine, but again after upgrade command, same thing happens. Not that skilled to debug this further. What I remember is that I saw in the upgrade log that kernel was updated, so thinking it might be that.
