no any version of 18.06 doesn't even boot on netgear wnr612v2.
I had no success to connect via serial port like on photos here https://wiki.openwrt.org/toh/netgear/wnr612v2
So I cannot attach any log file.
It's just booting
Currently default build of 17.01.5 for wnr612v2 is booting but overlay not saving.
Used package builder for making minimal 17.01.5 image with LuCI:
make image PROFILE=REALWNR612V2 PACKAGES="luci -ppp -ppp-mod-pppoe -kmod-usb-core -kmod-usb-ohci -kmod-usb2 -kmod-usb-ledtrig-usbport"
works great. 18.06 could be better to have.
looks like tiny builds for wnr612v2 are all faulty, tried all versions.
One more thing, factory image is flashed only to 14.04 then sysupgrade from LuCI. Any newer version fails to boot after being flashed from netgear's firmware webinterface.
thanks!
For those not very familiar with the various OpenWRT image-building tools, perhaps the simplest is the "Image Builder" that assembles pre-compiled packages into an image for your device.
It typically requires a Linux-based OS, either on a stand-alone machine or in a Virtual Machine (VM), such as the "free" VirtualBox application.
To reduce image size you will have to remove packages from the "stock" distribution. LuCI is a big one, but removing unneeded kernel modules (such as PPP, PPPoE, ...) may provide enough space. There is no "magic answer" to "How much is enough?"
The other option is the full build chain, which is not much more complicated.
Sorry for late answer. I used tftp tool from this article which only recover to any firmware version provided by netgear. Note, that it can fail to upload image by tftp. So I used Wireshark to monitor if there is any traffic and made 2-3 attempts until succeed to flash original firmware. Then only 14.04 is installed from web interface. And then I upgraded to image made with package builder with parameters from my post. If you want, I can send you my image, or build for you, I have a ready linux system to build a new one
You don't need to tell me, I already know.
Maybe you didn't get the intention of this topic: Collect information about which devices are affected by too little space to save configs.
Sorry, I thought I was answering to guy you cited. Anyway image builder with 18.06 doesn't help in my case. It just falls to cyclic rebooting with same singnals on led. router answers the pings on lan port
about 5 sec then reboots. If somebody could help me connect serial port on the device, I could provide log. I used pl-2303 chip.
Not sure what can I omit from here using the image builder )
The history: (just for whining)
A friend flashed it for me (can't remember the version, but he did it like 1-3 months ago, seems like it was 17), then I've found out that it doesn't save the config and boots into default config including passwordless root login on all interfaces.
So, I've flashed 15.05.1, since it was on the OpenWRT wiki for the device a month ago (I was lost in architectures and download links and didn't want to risk bricking the router). The config survived reboot, but I've just installed a fresh xubuntu 18.04.1 onto my laptop and it was working ok for half an hour and then started losing connection once per minute both through wifi and ethernet, also lost the connection on eth so it couldn't even get an ip. I thought it could be because of an old firmware. (Seems like it was not the firmware, because it still doesn't connect and the windows box works ok, so did the ipad and iphone/androids)
I've watched the logs on the router and detected that it was sending dhcp handshakes to the laptop. Nevertheless I decided to upgrade the firmware and flashed the new 18.06.1 (the new link is in the wiki today).
You might have similar symptoms, but at 32 MB flash it's impossible that the release images would be too large - so that would need debugging (and a different thread).
