After updating to new firmware the board not booting and wait on u-boot state => version U-Boot 2019.04-armbian (May 08 2019 - 10:38:01 +0200) Allwinner Technology aarch64-linux-gnu-gcc (Linaro GCC 7.4-2019.02) 7.4.1 20181213 [linaro-7.4-2019.02 revision 56ec6f6b99cc167ff0c2f8e1a2eed33b1edc85d4] GNU ld (Linaro_Binutils-2019.02) 2.28.2.20170706 Please advice, is it possible to upload new image somehow? I mean, without flashing sd card, just in u-boot console

Please advice, how to restore old dtb files? After upgrade to 5.1.7 (debian), OPi3 system became unstable and hang in maximum 50 minutes (sometimes immediately after reboot) Tried to rollback dpkg: warning: downgrading linux-dtb-dev-sunxi64 from 5.89.190614 to 5.89.190612 but still same issue.

apt upgrade returned following Setting up linux-image-dev-sunxi64 (5.88.190529) ... Error! Your kernel headers for kernel 5.1.5-sunxi64 cannot be found. Please install the linux-headers-5.1.5-sunxi64 package, or use the --kernelsourcedir option to tell DKMS where it's located Unfortunately, there is no linux-headers-5.1.5-sunxi64 package

I have a local OpenVPN server on Banan Pi M1, with latest armbian.

After installation, /etc/apt/apt.conf.d/50unattended-upgrades is empty. What is the proper origins to automatically install at least security patches?

As I understand from https://github.com/armbian/build/commit/69c231dbc0f6a67adea9c487b52b0482ebac3511 currently WireGuard is disabled. So, should I build image on my box with patch to enable it?

Is it possible to integrate wireguard into armbian for opi3, as for banana pi? Currently, lsmod | grep -i wireguard returns empty

1. How to update opi3 with new builds? apt dist-upgrade? 2. How to turn off red light on op3 board?

Time to time i got following notification on Banana Pi M1. Only after reboot Banana starts working properly. How to tune zram to avoid such kind of issue? No tuning made till now Linux bananapi 4.19.17-sunxi #5.73 SMP Mon Jan 28 21:06:40 CET 2019 armv7l GNU/Linux error: Compressing program wrote following message to stderr when compressing log /var/log/letsencrypt/letsencrypt.log.1: gzip: stdout: No space left on device error: failed to compress log /var/log/letsencrypt/letsencrypt.log.1 error: Compressing program wrote following message to stderr when compressing log /var/log/wtmp.1: gzip: stdout: No space left on device error: failed to compress log /var/log/wtmp.1 error: Compressing program wrote following message to stderr when compressing log /var/log/btmp.1: gzip: stdout: No space left on device error: failed to compress log /var/log/btmp.1

Interestingly, that after upgrade from 4.14 to 4.19 wg still working without recompiling. Magic?

WireGuard is a modern VPN service for Linux. For best performance it is requred to build WireGuard as kernel module (described at https://www.wireguard.com/install/) Right now after each update of kernel of Armibian WireGuard stops work as new kernel has no compiled wireguard.ko module Is it possible to integrate WireGuard to Armbian kernel?

Looks like USB drive is broken. Today at night banana reboted and starts to reboot again and again seconds after boot till I disconnected usb drive physically. Log https://pastebin.com/GmHP8tgC

Yes, with Transmission downloading started and finished without any issues, but - limited to about 10 MB/s While rTorrent downloading in about 18-20 MB/s. Right now I have set download speed limit for rtorrent to prevent disconnects.

Yesterday I have installed Armbian to my 3-years-old banana-m1 (previosly ran on bananian 16.04 with 4.4.66 kernel) Tiday I have installed rtorrent and tried to download 44 gb file using rtorrent (with lot of seeders). Few minutes, and I got massive bunch of errors [11583.126199] blk_partition_remap: fail for partition 2 [11583.126314] blk_partition_remap: fail for partition 2 ... [11583.136689] blk_partition_remap: fail for partition 2 and USB drive reconnected in ro mode. Then I remount drive, started torrent again and exactly same issue, USB drive disconnected. USB drive connected with external power.
