i have a Netgear DGN3500 witch OpenWrt SNAPSHOT r6013-112f046
i like to have luci be default, can i do it via sysupgrade ?
thanks

You can just install the LuCI package if you want to stay on the snapshot.

i do it but i missing some dependency if i try to install kmod-usb-net-rndis

any sugestion ?

To flash a sysupgrade from the command line, get the file into /tmp then run sysupgrade filename.

You can use a release build or get a new snapshot, then install all your packages especially kmods immediately. They become obsolete the next day.

5

The DGN3500 is on stable release, so the OP may be talking about going to that.

That's expected behaviour for snapshots.

https://openwrt.org/faq/after_installation#cannot_satisfy_dependencies

snapshots are built daily, and that sets time limits to installing new packages with opkg. Due to kernel version checksums, you can only install “kmod” kernel modules and other kernel version dependent modules from the exactly same snapshot build. So, a few hours after flashing the firmware you may not be able to install new modules with opkg any more (as the next snapshot has been built into the download repo and has different checksums).

7

You could also use the buildroot (imagebuilder too I think) to compile luci with whatever kernel version you're currently on. In order to make configuring a buildroot simpler, I created a script a while back which automates the entire process.

  • Since you're just looking to compile one package, once "...Compiling Image..." begins, simply CTRL+C to cancel it
    • Modify the kernel version in source/include/kernel-version.mk
    • Once done, issue: make /package/feeds/luci/luci/compile

You can, but you should wipe your settings

# sysupgrade -n $sysupgrade.image

i solve my problem via the mini webserver , ca by lunched via the serial port

run - run commands in an environment variable
saveenv - save environment variables to persistent storage
sercommtrap - do sercomm trap utility
setenv - set environment variables
sleep - delay execution for some time
tftpboot- boot image via network using TFTP protocol
upgrade - forward/backward copy memory to pre-defined flash location
version - print monitor version
web - do sercomm web emergency revoery

end the downgrade its done :smiley:
