Hello, After more research it seems that despite the Wikipedia screenshot, M2 Ultra & M2 Berry do not really have the same CPU : M2U uses R40 and M2B uses V40 This is most probably why it does not work. After checking watchdog & sysrq, I almost rebooted with : echo 1 > /proc/sys/kernel/sysrq echo b > /proc/sysrq-trigger but still hung in the end. I was about to throw the Banana PI away, and I finally found this website which provides a (very) raw debian image for the M2 Berry, and it works correcty including reboot. Sharing the link in case it helps other people with M2B : https://sd-card-images.johang.se/boards/banana_pi_m2_berry.html Thanks for your help Regards

Hello, Thanks for your answer, in fact I chose this M2U image because the hardware between M2B & M2U is almost the same : same CPU & arch, just a difference in RAM size & ports number (see image below) Maybe it is a "noob" way of thinking anyway, so I will try to adapt and find a solution around watchdog & sysrq, and if it does not work I will go back to raspberry pi. Have a nice day Regards

Hello Thanks for you answer, I understand the point that if even though M2B & M2U are very close, it does not mean it will work. I really thought it was a simple thing to change "just" to turn off/on the board, as all the rest is perfect. I had a look to https://docs.armbian.com/Developer-Guide_Build-Preparation/ but honestly I am not skilled enough to to this, I did not understand how building it on my PC will make it work on the BananaPi, and the config ./compile.sh build \ BOARD=uefi-x86 \ #bananapim2b does not seem to exist BRANCH=current \ BUILD_DESKTOP=no \ BUILD_MINIMAL=yes \ KERNEL_CONFIGURE=no \ RELEASE=trixie does not help on which string using for my board. Regards

Hello, Thanks for armbian on Banana PI, it is really wonderful compared to official releases. I installed the image "Armbian_community_26.2.0-trunk.904_Bananapim2ultra_trixie_current_6.18.29_minimal.img.xz" on my Banana PI M2 Berry (there is no image for this type), and all is working wonderfully well ... except rebooting or shutting down the Banana PI. When typing reboot, all services stop but the screen blocks on systemd-shutdown[1]: Rebooting. and it never reboots. It does the same for shutdown, stuck on same kind of message. Could you help me please ? Regards
