Online ImageBuilder and Upgrade Server

Hey @jeff I think I get your point and nobody is eager to produce any CDs. As long as opkg info or opkg list-installed does not print any information regarding the license, I can't really do anything. Once this is done I hope this information is included in the .manifest file and then available for every created image.

Hello @aparcar.

First, congratulations for your work.
I´m trying to create a build for my router, but i have a doubt.
Look at the files created:

I cannot see the factory and sysupgrade file..
Which of these files i can write into my router?


Check your buildlog for error messages, but this is almost always indicating that your image got too large - especially for 4 MB flash devices.

I'm afraid the refactoring broke the detection for "to big images". I'll try to update the server within the next hours

Hello @aparcar.

I agree with you...
Using online image builder from libremesh, i get an error when the image become too big.
It´s easy to fix this?

Another question: It´s possible to customize the squashs block size?
In other builds that other users did, it seemed that using the 1024Kb block size improved the compression level.


I have no experience with that, if you'd suggest to use that value for all LibreMesh image builder I can add a feature to change individual .config options. Please send me the related line & request comments on the LiMe mailing list.

However, making all .config options editable per requested image is a bit out of scope.

Hello @aparcar.

I don´t know how to do this too.
I have no experience with linux. My sugestion was based on builds from other users.
If somebody can help.


The problem seem to be that the snapshot ImageBuilder don't print the error message. Here is an example of a working version while sometime it just doesn't. I'll ask on the mailing list for some further help.

I'll ask the LibreMesh mailing list if this is recommended, if so I'll implement it.

The config option is TARGET_SQUASHFS_BLOCK_SIZE, and the default is 256. Increasing it will noticeably reduce the size of the image. The drawback is that three of those will be cached by default, so if you increase it to 1 MB then it will use 4 times more RAM. It can be reduced to 1 using make kernel_menuconfig, the setting is SQUASHFS_FRAGMENT_CACHE_SIZE. Setting it to 512 KB and 1 cache fragment could be a good idea on a 4/32 router, though. I don't know how much it would influence CPU usage.


Thanks for these details. I may implement a way to set custom config options per build, at least per distro/version so.

Sorry for the inconvenience, due to a badly formatted SQL join only requests containing custom defaults would be build. It should now work again. Please feel free to message me here or via mail in case of troubles, I'm happy for everyone who's testing and feedback in general!

this is a great tool and service. i've successfully built a customized image for my wrt32x.
thank you!

i ran into a problem building for ar71/ mr16: i tried to add wpad-mash and take away wpad-mini. the build failed with error wpad-mini asking for modules that wpad-mesh had alrady required. this message was generated in the build process whether i put wpad-mesh at the top or bottom oof the list, and whether or not i removed wpad-mini fmr the list. it seems wpad-mini is in the build list no matter what packages are in the package window

thanks again

Not clear from your post, have you included the -wpad-mini in the list (notice the preceding minus sign)? Some packages, which are included by default, need to be explicitly excluded (like -dnsmasq dnsmasq-full and -wpad-mini wpad-mesh).

@stangri -
AHA! thank you. i missed the - option to remove a default package.

now, we need an 18.06.1 version selection!

Thank you very much @aparcar , I had just created images for my nucom R5010U modems with version 18.06.0, they are working very well, only I had some problems in removing -odhcp and leaving the package odhcpd-ipv6only (the error was mine when wanting to copy the same packages of my tplink mr3220v2). Congratulations for your work.

Amazing work, built my own firmware for very first time yesterday. You sir are awsome!!

@aparcar: I've made a thread about what can be changed in the default configuration to save space and RAM here: Discussion about what can be removed/disabled/shrunk in images

It may be useful for your users if you add the possibility to change them. Most of them are simple yes/no choices.

Cool thanks, I'll have a look. I have no problem implementing the possibility to change the default config if it doesnt imply any security issues for the server side

Thanks for the notification, been offline lately. I just added the new release and the ImageBuilders are currently being downloaded and setup. All targets should be available within the next hour.

It is a bit strange that the versions 18.06.0 and 18.06.1 do not include inside the Luci profile, I thought that only snapshot lacked those packages in their respective profiles.
