Perhaps some memory configuration that is not supported with mainline boot loader? RK3399 can be booted with open source or closed source loader. We changed to open source at some point, but not on all boards. Perhaps this is the issue? We have a few of those acting as a build runners - no issues whatsoever: Spoiler _ _ ____ _ __ __ _ ___ ______ | \ | | _ \(_) | \/ | || \ \ / /___ \ | \| | |_) | | | |\/| | || |\ \ / / __) | | |\ | __/| | | | | |__ _\ V / / __/ |_| \_|_| |_| |_| |_| |_| \_/ |_____| Welcome to Armbian 22.08.6 Jammy with Linux 5.15.52-rockchip64 System load: 2% Up time: 74 days 4:04 Memory usage: 8% of 3.77G Zram usage: 3% of 1.89G IP: 172.17.0.1 10.0.40.22 CPU temp: 35°C Usage of /: 27% of 58G RX today: 2.5 MiB 0 Quote Link to comment Share on other sites More sharing options...

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 ?!

Like I said, unsupported memory chip in boot loader would explain those troubles. Probably it would work if you flash nonworking image with a u-boot from a working one.

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) ...

Igor Posted October 29, 2022 Share Posted October 29, 2022 I didn't say installing package will do the job Explore .deb file. Flashing is purposefully manual - via armbian-config - if your system is up and working. 0 Quote Link to comment Share on other sites More sharing options...
neoxnitro Posted October 29, 2022 Author Share Posted October 29, 2022 Hehe 😅 Ok, everythings works !
