@crispyoz thank you for your reply. I am not familiar with shell program that i ignore build scripts and profile, So I consider "clean_imagebuilder" as reload build at first. Thanks your guide and support, I know what happen while image build, I has fix my build and run each test several times. Now imagebuilder work as my expectation that I can take attention to my application develop right now.

@luz Yes, I used the openwrt-imagebuilder-wrapper from onion's GitHub repo to generate my own customized firmware. Thank you very much for your suggestion.

Hi,teams

My purpose is to write the device identity authentication information into my customized Omega2+ device. I hope this part can be firmly stored in the device (retained even after system restore).

I confirm writing uboot variable is available on uboot environment, refer by https://community.onion.io/topic/2272/what-does-this-message-mean_=1767832343343.

But modify uboot variable only on boot environment is not good idea for me, fw_setenv is available on system environment? Permission Denied for /dev/mtd1 When Executing fw_setenv.

@crispyoz thank you answer, I run you suggestion and test, it run as you say.
To my question, actually possible operatetion mistake.I do a repeartion. while type in "bash clean_imagebuilder" , directory openwrt-imagebuilder/ is gone. when I generate it again. Unusual, I found my target file mycfg.conf still alive. I build image and upgrade on omega2+, custom is effective

Hello：

I need to build custom firmware on Onion omega2+. I try openwrt-imagebuilder-wrapper to work, but add custom file is no effective. Above is my operation :

• type in command "bash onion_buildenv setup_imagebuilder" would generate
  directory openwrt-imagebuilder/

• create new diectory files/etc on additions/(Completion path: /home/user/openwrt-imagebuilder-wrapper/additions/files/etc/)and add target file mycfg.conf

• type in command" bash onion_buildenv build_all_firmware ",I get binary file onion_omega2p-23.05.3-20240909.bin on output/

when i upgrade omega2+ with command "sysupgrade -F -n onion_omega2p-23.05.3-20240909.bin", can not find target mycfg.conf in /etc

PS: I git clone repo, I follow recommand text “bash onion_buildenv setup_imagebuilder” in terminal show above error:

tar (child): /home/mulu553/openwrt-imagebuilder-wrapper/openwrt-imagebuilder-23.05.3-ramips-mt76x8.Linux-x86_64.tar.xz: Cannot open: No such file or directory

but it's not key, because i can download openwrt-imagebuilder-23.05.3-ramips-mt76x8.Linux-x86_64.tar.xz form http://downloads.onioniot.com/releases/23.05.3/targets/ramips/mt76x8/
