Hehe 😅 Ok, everythings works ! For people with same problem than mine, this is what i did Install u-boot Debian package, one that you knows works (download via: https://imola.armbian.com/apt/pool/main/l/linux-u-boot-nanopim4v2-current/) dpkg -i linux-u-boot-current-nanopim4v2_xxxxxx_arm64.deb Launch armbian-config tool sudo armbian-config System -> Install -> Install/update the bootloader SD/eMMC The SD is now bootable Thx again to Igor for his help 🤜🤛

sudo dpkg -i linux-u-boot-current-nanopim4v2_21.02.3_arm64.deb (Reading database ... 81517 files and directories currently installed.) Preparing to unpack linux-u-boot-current-nanopim4v2_21.02.3_arm64.deb ... Unpacking linux-u-boot-nanopim4v2-current (21.02.3) over (21.02.1) ... Setting up linux-u-boot-nanopim4v2-current (21.02.3) ... I installed the package into my current system and ... boom ... the sd booted ... how does it possible, it's magic !! ... thanks dude Ok, i said "Yesss" too quickly ... aftet the reboot, the system booted via the micro SD, i copied the sd content to emmc (via armbian-config tool) and after that, nothing boot anymore I installed again "buster" version ... but this time, i will flash bootloader of SD card via armbian-config tool ...

What is the seek and bs parameters values for the dd command to flash the .deb file into the SD card ? where can i find them ?

Yes, may be is related to my USB to Serial adaptor ?! I verified ... it's well a V2 ... but i noticed something weird, i only have 2 Go of RAM ... and in the output you shared you have 4 Go RAM, does it possible that my boot problem came from there ?!

Hi, My NanoPi M4 V2 Won't Boot via SD ... the emmc is not installed on the board The RED light is ON but the GREEN stay OFF I cannot reached to read correctly the data coming from the serial port debug (I tested with many bauderate, also with 1500000, same result ... a lot of weird characters) Tested Versions Won't boot: Armbian_22.08.1_Nanopim4v2_jammy_current_5.15.63.img.xz Armbian_22.08.1_Nanopim4v2_bullseye_current_5.15.63.img.xz Armbian_22.11.0-trunk_Nanopim4v2_sid_edge_6.0.3.img.xz Armbian_22.11.0-trunk_Nanopim4v2_kinetic_edge_6.0.3.img.xz Tested Version Boot properly: Armbian_21.02.1_Nanopim4v2_buster_current_5.10.12.img.xz I use a workbench power supply 5A ... with current limitation set to the max value I tested many SD card (all are class 10) What i'm doing wrong ?! What could i verify ? Any idea ? Thanks guys
