@SteeMan this is supposed to be a remote and unattended system, so I would like to control the updates very carefully in order to avoid breaking anything using apt (it happens sometimes...). I know this is quite a challenge, but frameworks like rauc and swupdate are purposely designed to guarantee atomically and safe system upgrades. I would disable apt unattended system upgrades, protect the rootfs using overlayroot and possibly use rauc to upgrade the systems using a full image. I am also evaluating tools like systemd-repart that may repartition the storage (eMMC, or SD) live.

Hi all, has anyone ever tried to use an atomic firmware upgrade system like rauc or swupdate? https://rauc.readthedocs.io/en/latest/ https://sbabic.github.io/swupdate/swupdate.html I am playing with rauc, in order to do that I have to customize the partitioning of the SD/eMMC: - root1 (4GB) - root2 (4GB) - data (8GB, or remaining space) Can someone suggest how to customize partitioning in such way? I played around setting USE_HOOK_FOR_PARTITION=yes, and hooking the create_partition_table but had no luck. Any hint? Thanks in advance! Andrea

Thank you @going, I will evaluate this.

Is it possible just to rebuild the kernel, without fetching kernel updates and reapplying patches? I would find it useful to develop kernel drivers like in a development cycle.

Any success with this? I have the same question

A custom designed board around H616.

Hi all, is it possible to flash the a board's eMMC via USB from another PC? I already checked this but could not figure out exactly how. Thanks in advance, kind regards

Thanks for the advice!

Hi all, Armbian v23.11 build fails while compiling ATF, reporting weird "cannot find cr" message: https://paste.next.armbian.com/evewilodap Can you please help? Thanks in advance!

Charge pump is a very simple topology of DC-DC switching converter, normally driven by SoC PWMs. I have checked the DT yaml, but could not find anything useful. I found a PWM driver for Allwinner H6, but it does not work (I get error -22, EINVAL when loading the driver module).

Is it possible to rebuild the kernel without reapplying all the patches?

Hi all, I would like to use the PWM1 in order to drive a charge pump, but I am struggling to enable PWM using the DTB on Armbian v23.11. Anyone succeeded in configuring PWMs in H616? Thanks in advance!

Hi all, I need to customize the /etc/fstab during the build to mount a mtd partition and also to override some mountpoints with tmpfs in order to reduce wearing on mmc. So, have added the following lines to customize-image.sh: cat <<EOT >> /etc/fstab # Reduce SD wearing by storing log files into ram (no need as overlayroot is used to freeze all the rootfs) tmpfs /tmp tmpfs defaults,noatime,nosuid,nodev 0 0 tmpfs /run tmpfs defaults,noatime,nosuid,nodev 0 0 tmpfs /var/tmp tmpfs defaults,noatime,nosuid,nodev 0 0 tmpfs /var/log tmpfs defaults,noatime,nosuid,nodev,noexec 0 0 tmpfs /var/lib/logrotate tmpfs defaults,noatime,nosuid,nodev,noexec,size=1m,mode=0755 0 0 tmpfs /var/lib/sudo tmpfs defaults,noatime,nosuid,nodev,noexec,size=1m,mode=0700 0 0 # MTD EEPROM memory dev/mtdblock0 /mnt/mtd jffs2 ro,relatime 0 0 EOT However changes in /etc/fstab are overridden somewhere over the build process, and this is the resulting /etc/fstab: UUID=c8167755-b557-4288-9109-9108bc48dd94 / btrfs defaults,noatime,commit=600 0 1 UUID=27ac6cc6-eff3-4736-a7bd-5517e3b150c0 /boot ext4 defaults,commit=600,errors=remount-ro 0 2 tmpfs /tmp tmpfs defaults,nosuid 0 0 Is there a way to safely patch the /etc/fstab file? Thanks very much! Andrea

Hi all, I need to add some packages to Armbian in the build phase. I tried two ways, both failed: 1. Had run through docs (https://docs.armbian.com/Developer-Guide_User-Configurations/), and the suggestion is to add a var PACKAGE_LIST_ADDITIONAL in userpatches/lib.config PACKAGE_LIST_ADDITIONAL="$PACKAGE_LIST_ADDITIONAL watchdog modemmanager iptables iptables-persistent dnsmasq bridge-utils iproute2 openvpn" Building the image I get the following error: [🌱] Using user configuration override [ /home/andrea/armbian/build/userpatches/lib.config ] /home/andrea/armbian/build/userpatches/lib.config: line 1: PACKAGE_LIST_ADDITIONAL: readonly variable [💥] Exiting with error 1 [ at /home/andrea/armbian/build/userpatches/lib.config:1 source() --> userpatches/lib.config:1 do_extra_configuration() --> lib/functions/configuration/main-config.sh:352 do_with_logging() --> lib/functions/logging/section-logging.sh:81 do_with_conditional_logging() --> lib/functions/logging/section-logging.sh:111 prep_conf_main_build_single() --> lib/functions/main/config-prepare.sh:34 cli_standard_build_run() --> lib/functions/cli/cli-build.sh:22 armbian_cli_run_command() --> lib/functions/cli/utils-cli.sh:136 cli_entrypoint() --> lib/functions/cli/entrypoint.sh:176 main() --> compile.sh:50 ] [💥] Cleaning up [ please wait for cleanups to finish ] 2. Customizing userpatches/customize-image.sh: Added the following lines to the aforementioned file: CUST_PACKAGES="watchdog modemmanager iptables iptables-persistent dnsmasq bridge-utils iproute2 openvpn" apt-get install -yy $CUST_PACKAGES |& tee -a $DEST/${LOG_SUBPATH}/custom.log The build completes, but packages aren't added as the logging prevents the build to fail. Anyway the following info messages are displayed during the build: [🔨] Reading package lists... [🔨] Building dependency tree... [🔨] Reading state information... [🔨] Package modemmanager is not available, but is referred to by another package. [🔨] This may mean that the package is missing, has been obsoleted, or [🔨] is only available from another source [🔨] [🔨] Package iptables is not available, but is referred to by another package. [🔨] This may mean that the package is missing, has been obsoleted, or [🔨] is only available from another source [🔨] However the following packages replace it: [🔨] libxtables12 [🔨] [🔨] E: Unable to locate package watchdog [🔨] E: Package 'modemmanager' has no installation candidate [🔨] E: Package 'iptables' has no installation candidate [🔨] E: Unable to locate package iptables-persistent [🔨] E: Unable to locate package dnsmasq [🔨] E: Unable to locate package openvpn Can you suggest a suitable way to add packages to the build? Thanks very much in advance, kind regards Andrea
