Re: ubiquiti EdgeRouter X (ER-X)

I've been testing the trunk version on the SFP version of the router and the main thing that's missing is the ability to enable the poe on the ports. Has anyone worked out how to enable this? I've tried all the GPIO info in the wiki but nothing so far.

Does anyone know if an updated version of this has been released.?

I have just purchased one and am getting garbage over the serial port. I'm assuming it's a baud problem and have tried all rates from 9600 to 230400. I have had success with a Edgerouter lite so I know my serial hardware is ok.

The board on mine also look different from the photo on the page.

I agree, just opened up a new one I got last week and it is similar to yours with a single screw on each side.

Re: ubiquiti EdgeRouter X (ER-X)

HI, I am trying to setup OpenWrt on Edgerouter X but need some help.

I am following the instructions at the TOH wiki page (sorry, I am not allowed links). I got the serial console to work, but something must have changed in the build system. In menuconfig after choosing

Target system: Ralink RT288x/RT3xxx
Subtarget: MT7621 based boards

there is no way to choose

Target profile: Ubiquiti EdgeRouter X

In fact there are no profiles to choose from other than "default profile". Digging through git history I found that they they were all deleted in this commit (again, can't link...):

"ramips: convert a bunch of targets to new image building code"
Commit 15458e85bc42672eb06dee5fb45597298b4a7162

So how/where do I choose the new equivalent of a target profile?

Thanks

Re: ubiquiti EdgeRouter X (ER-X)

OK, I figured out how to build the initramfs image (had to enable it in menuconfig) and I now have working OpenWrt.

However, switching back to stock firmware does not work. I can flash it using serial console and TFTP and it starts booting, but then it fails with UBI error and kernel panic.

Someone here in this thread (post #21) mentioned that you have to

restore rootfs mounting its UBIFS volume

. But I don't know what that means or how to do it?

Below is the error that I am getting. Can anyone help?

Thanks

Re: ubiquiti EdgeRouter X (ER-X)

Hello all

Because of it's low price and seemingly good hardware, I am interested in this model. I would like to know the state of openwrt support for this model. Are you guys running the trunk versions without issues? in particular, i am interested in running openvpn on it and use it as a openvpn server. have any of you guys tried that and successfully established a vpn connection?

I would appreciate your input very much.
thanks

Best Regards,

Re: ubiquiti EdgeRouter X (ER-X)

@combolek
How did you exactly flash it? From what i've read so far, it appears to me that the safest way to flash back to the stock firmware via uboot enviroment is to locate the kernel part and the ubifs part (which includes the squashfs file) in the firmware, then figure out which kernel is the active one, and then separately flash back kernel and ubifs partition.

Edit: well, what do you know. they're already separated in the stock fimeware .tar file

Best Regards,

Re: ubiquiti EdgeRouter X (ER-X)

I tried different methods of flashing but the results are pretty much the same. First I tried using the bootloader option 2 to flash from TFTP (concatenated kernel+rootfs). I also tried flashing separately kernel and rootfs as you say, using mtd while booted the initramfs openwrt image.

I do not know how to flash directly from uboot command line. What are the commands?

AFAICT, openwrt is working fine, though I am only using it as a basic router/firewall. I have not tried openvpn.

Re: ubiquiti EdgeRouter X (ER-X)

Unfortunately i do not know much about UBI yet but i'm pretty sure the issue relies on squashfs that needs to be inside a UBIFS partitions. according to the guy who added openwrt support for this device:

Stock firmware uses custom kernel patch to mount squashfs from a file that is located on UBIFS volume.

This should possibly involve creating UBI/UBIFS then copying the squashfs file to that partition and potentially renaming it. base on how the custom kernel patch works, extra steps might be needed.

I suggest you directly try contacting the author of the openwrt patch (his email address is in the patch file). he should be able to solve this mystery.

for flashing in u-boot environment, you could use this as a reference:
https://wiki.openwrt.org/doc/howto/gene … ing.serial
Though i do not think this would be necessary for reverting back to the stock firmware.

Best Regards,

Re: ubiquiti EdgeRouter X (ER-X)

Oh, thanks, will try this.

Actually, given that OpenWrt works fine and that's what I intend to use, I don't really need to go back to stock firmware. I just don't like the one way street on principle :-)

35 (edited by Hamy 2016-09-15 09:23:44)

Re: ubiquiti EdgeRouter X (ER-X)

One more hack that might be worth trying is making a custom sysupgrade image actually containing stock firmware and use openwrt sysupgrade to flash it to the device(don't forget to add -n flag) . making such image is pretty simple, just extract both stock and sysupgrade tar files and you could figure it out.

just make sure that you're ready to recover from it in case things go wrong

Edit: Actually, scratch that. it likely wouldn't work.

Best Regards,

Re: ubiquiti EdgeRouter X (ER-X)

OK, success. Someone else has figured it out :-). I used this post:
https://community.ubnt.com/t5/EdgeMAX/W … 85#M128414
Once I followed the steps to recreate the ubifs volume I was able to get back to stock firmware no problem.

So, now I can reflash OpenWrt again and keep using it with a piece of mind :-).

Re: ubiquiti EdgeRouter X (ER-X)

Great. please also consider adding the necessary steps the wiki so others could benefit as well.

But you can still run OpenWrt without problems, right?

Are there any issues with OpenWrt on ER-X devices or is everything working perfectly?

Re: ubiquiti EdgeRouter X (ER-X)

Just a side note for users wishing to switch to third party firmwares (like openwrt):
Always try to backup all original mtd partitions. sooner or later, you might need them. in case of this device, it likely just need a slight adjustment of ubf/ubfs settings/partitions. but aside from the fact that you could have restored the original mtds to revert back to the stock firmware and be done with it, they could have helped to uncover whats wrong what needs to be adjusted.

Best Regards,

Re: ubiquiti EdgeRouter X (ER-X)

@Hamy can you write up a short how to on wiki. It would be really helpful to have steps needed to backup and restore mtd partitions. For some who does this for first time it is a daunting task.

Yes, as far as I can tell OpenWrt works fine. I don't know of any problems but I am probably using only a small subset of the features.

thx a lot

Re: ubiquiti EdgeRouter X (ER-X)

Hello,
I am having issues upgrading a UBNT ERX from the factory openwrt image as follows.
Thank you very much in advance for your expert advice.

The problem is I am getting a system crash and reset when performing sysupgrade.
The factory image installed fine with the add command after compiling.
       DESIGNATED DRIVER (Bleeding Edge, r49395)

I have tried upgrading with the latest download from
     openwrt-ramips-mt7621-ubnt-erx-squashfs-sysupgrade.tar
as well as the tar file that make menuconfig created.

These are the commands that I wrote on a VirtualBox session of Ubuntu running on a Windows 7 host to build the compiled tar files:
git clone ... openwrt.git
cd openwrt
./scripts/feeds update -a
./scripts/feeds install -a
make menuconfig

These are the options I selected:
Ralink RT288x/RT3xxx
MT7621 based boards
Ubiquity Edge Router X
ramdisk
squashfs

this is the console view after running sysupgrade:

Re: ubiquiti EdgeRouter X (ER-X)

Try using the -n switch when doing the sysupgrade to wipe the current config

sysupgrade -n openwrt-ramips-mt7621-ubnt-erx-squashfs-sysupgr
ade.tar

Re: ubiquiti EdgeRouter X (ER-X)

Webtron,
I tried the -n switch, and the same thing happens. It crashes and reboots.
One thing to tell you is that I followed the procedure on the openwrt site for clearing up memory for sysupgrades, in case the problem was lack of sufficient memory. This entailed deleting the cache and two directories.
Before I performed this step, I would receive a command failed error, and then sysupgrade exited, but the box did not reboot.
I did attempt the sysupgrade with the -n switch also.
Now that the directories are removed, it doesn't get as far and then it crashes. So apparently releasing memory created another problem.
Can you advise what the procedure is to recover, or to reinstall the factory image from an existing factory image? Do I need to recover back to the UBNT OS, and start again, or is there a simpler method if I already have the factory image on board?
Thank you for your assistance.
Regards,
John

Re: ubiquiti EdgeRouter X (ER-X)

I've managed to make it work but hit a couple snags following the instructions on the wiki.

* First, there is no "Target Profile" for the EdgeRouter X.  Only the default profile is available.

However, in order to build the "factory" image, the entire system must fit into 3 MB.  So if you just use the default settings, the build will fail.

So you will need to go through the menuconfig and manually remove some unnecessary packages, such as WiFi and USB packages, in order to get the build to succeed.

I used the following:

 Target System: Ralink RT288x/RT3xxx
 Subtarget: MT7621 based boards
 Target Profile: Default Profile
 Target Images > ramdisk: Y
 Kernel Modules > Wireless Drivers > kmod-mt76: N
 Kernel Modules > Wireless Drivers > kmod-mac80211: N
 Kernel Modules > Wireless Drivers > kmod-cfg80211: N
 Kernel Modules > USB Support > kmod-usb3: N
 Kernel Modules > USB Support > kmod-usb-core: N
 Utilities > iwinfo: N
 Network > iw: N
 Network > wpad-mini: N
 Network > hostapd-common: N
 Libraries > libiwinfo: N

* Second, failsafe mode is BADLY broken: the device does not respond to any network activity on any port.  This is apparently because the switch is configured to use VLANs by default, but failsafe mode doesn't understand that.  The script /lib/preinit/07_set_preinit_iface_ramips works around the same issue for certain other models.

It seems to me that this workaround is a security risk; unless I'm missing something, this script is invoked at every startup (failsafe or not), which would mean that the router is, if only briefly, acting as a dumb switch.  If an attacker were able to exploit some other bug that would cause the router to reboot, this would give them a short window during which they could send packets that bypass the firewall.

At any rate, here's how to enable the workaround for ERX.  (I have no idea whether this is appropriate/necessary for *all* MT7621 devices or not.)
