Devolo Dlan 1200 Wifi AC device (non-pro version) #3

Open SteveAyre opened 5 years ago

SteveAyre commented 5 years ago

I've successfully built openwrt 18.06.01 for the dlan-pro-1200-ac with dlan-openwrt and the MT2675 PIB & NVM driver from firmware.QCA9882-v2.2.0_2018-07-26.dv and installed this on the white non-pro version.

While it boots fine and LAN and Wireless both work I am having trouble getting PLC to work. All commands appear to give an immediate 'read timeout or network error'.

For example:

root@OpenWrt:~# /usr/bin/plctool -i "$PLC" -B"1" "$MAC"
br-lan 30:D3:2D:C3:FD:D6 Join Network
plctool: PushButton: Read timeout or network error
root@OpenWrt:~# 
root@OpenWrt:~# /usr/bin/plctool -i "$PLC" -B"join" "$MAC"
br-lan 30:D3:2D:C3:FD:D6 Join Network
plctool: PushButton: Read timeout or network error
root@OpenWrt:~# /usr/bin/plctool -i "$PLC" -B"status" "$MAC"
br-lan 30:D3:2D:C3:FD:D6 Fetch Network Status
plctool: PushButton: Read timeout or network error

Is it possible for this device to be supported? Would it require further changes to OpenWRT or should the pro target be suitable?

Any idea what would cause the Read timeout error?

dvlemplgk commented 5 years ago

Hi Steve

The plctools don't work properly on bridge interfaces, you'll have to provide the underlying eth interface where the PLC chip is connected to. In this case it's eth0. And there are stray 'br-lan' and 'Join' arguments in your commandline above. Positional parameters must be MAC addresses.

e.g. /usr/bin/plctool -i eth0 -B 1 "$MAC" /usr/bin/plctool -i eth0 -B join "$MAC"

where MAC = the mac address of the PLC chip, which is configured in the pib during boot up. You can get it with plctool -i eth0 -a

dvlemplgk commented 5 years ago

If you build the packages, the firmware and pib you extracted from firmware.QCA9882-v2.2.0_2018-07-26.dvl must be copied to the directory qca/dlan-pro-1200-ac. Firmware must have extension .nvm pib must end with -mt2675.pib (in your case for MT2675) so the package can be properly built. These names are expected by the Makefile.

The generated fwconfig file should the look similar to this: PLCFW_PATH=/lib/firmware/plc PLCFW_NVM='dlan-pro-1200-ac/MAC-7500-v2.6.0-01-NW6__-X-CS.nvm' PLCFW_PIB='dlan-pro-1200-ac/qca7500-pib15-devolo-mt2675.pib' PLCFW_PIB_2675='dlan-pro-1200-ac/qca7500-pib15-devolo-mt2675.pib' PLCFW_HOST=/usr/bin/plchost PLCFW_SCHEMES=$PLCFW_PATH/dlan-pro-1200-ac

SteveAyre commented 5 years ago

Updated codeblock formatting to separate commands and output better - they weren't stray br-lan/Join arguments but it did appear that way on a single line.

Thanks for the clarification on the br-lan vs eth0 interface.

The MAC also appears to have been the issue as plc.init detects and updates the PIB with 30:D3:2D:xx:xx:xx but plctool reports a 10:0D:7F:xx:xx:xx address.

The commands you gave work so I will now look at how to get plc-pushbtn to use the correct one.

OXINARF commented 5 years ago

@SteveAyre Nice to see someone else attempting this. I now have PLC working with latest OpenWrt stable version (18.06.1). But I haven't found how to save the security-id when using the push button - after a reboot I have to join it to the network again. @dvlemplgk any tips?

@dvlemplgk As far as I can tell, the delos firmware is no longer in development. If that is correct, would @devolo consider open sourcing parts of it? I understand that some parts are proprietary and wouldn't/couldn't be open, but other parts would be nice to have (even if they don't work/build).

dvlemplgk commented 5 years ago

@OXINARF After successful pairing the key (NMK, which is not the security-id) is saved in the PIB file (/lib/firmware/user.pib resp. user.pib.tmp) by plchost. Those files should be persistent and be used after reboot. Only after firmware reset you would have to pair them again. Please check with modpib /lib/firmware/plc/user.pib.tmp -v which NMK is set after pairing,

OXINARF commented 5 years ago

@dvlemplgk Thanks for clarifying! It didn't work (multiple times) before, but first time I connected it today, it indeed connected to the network without having to re-pair.

I still have to properly test Wifi, but I guess the only thing that is broken is the dLan led trigger, it gives an error request_irq failed with error -22. The led works by manually turning it on, but when setting the gpio (for gpio triggering) it gives that error and led stays off.

dvlemplgk commented 5 years ago

Then your Linux kernel gpio driver seems to not support interrupts for ath79 gpios. They were introduced in linux 4.6. And there's a hardware bug which makes edge triggered interrupts unreliable, you have to add this patch to the kernel >=4.6:

OXINARF commented 5 years ago

Thanks, I'll have to try that later. I'm using OpenWrt 18.06.1, which has kernel 4.9 so it should have support.

Is there any reason why that couldn't be a patch on OpenWrt (or even submitted to kernel)? \ \ \ \ (correctly formatted diff below)

dvlemplgk commented 5 years ago

Maybe noone is using led gpio interrupt trigger so it went unnoticed? We didn't upstream this patch yet. Sorry for mangled format. How do you format code properly here (I used 'insert code' button)?

OXINARF commented 5 years ago

Best way is to paste it, then select it and click the insert code button. When it's multiple line you need to use three (or more) backticks and it correctly inserts it if you select multiple lines.

It usually detects the parser correctly but for the above it didn't, so here is what I did there:

~@dvlemplgk Any idea what can lead to the following error starting the PLC interface?~

~I have a MT2913 working perfectly but now with two new MT2910 I always have this error.~

EDIT: Nevermind, it was the firmware itself that wasn't working. For some reason, OpenWrt 18.06.2 works well, but 18.06.1 doesn't on MT2910.

SteveAyre commented 5 years ago

Note the trigger requires kmod-ledtrig-gpio (I didn't have it installed at first).

I'm also seeing 'request_irq failed with error -22' even after applying the patch above?

SteveAyre commented 5 years ago

firmware.QCA9882-v2.2.0_2018-07-26.dvl no longer seems to be available on http://devolo.de/

Is there a download for that firmware or a more recent version anywhere on the devolo website?

SteveAyre commented 5 years ago

I have found devolo-firmware-dlan1200-wifiac_5.2.1-2_i386.deb on http://update.devolo.com which contains delos_dlan-1200-ac_5.2.1_2019-02-19.bin.dvl which appears to have the required nvm and pib files. Is this the correct current version?

Molkenbur commented 5 years ago

Yes, you are right. This is the latest firmware for dLAN 1200+ WiFi ac. We deploy it via the Cockpit tool to our customers. Same is valid for dLAN 550 WiFi.

OXINARF commented 5 years ago

Wow I thought that delos firmware was dead, but it's now the official firmware for all the older wireless devices. I'll need to check it out when I have time.

Molkenbur commented 5 years ago

Not all the older wireless devices, to be honest. The cut is for the latest low cost and premium dLAN devices based on HomePlug AV2 And for all new Magic devices based on G.hn as well. BTW: All are using Wi-Fi chipsets from Qualcomm. Maybe, you want to wait for the upcoming version 5.3.0.

mgiganto commented 5 years ago

Do you know where is the serial port on devolo dlan devices? I am working in the openwrt support for devolo magic 2 wifi but most probably, the serial port is common for all dlan devices.

SteveAyre commented 5 years ago

Do you know where is the serial port on devolo dlan devices? I am working in the openwrt support for devolo magic 2 wifi but most probably, the serial port is common for all dlan devices.

I'd be pretty careful looking for the serial port given the proximity to mains AC voltage.

I didn't need serial port access to install openwrt, so I don't know where it's located.

Hi,

Does anyone have a refined process to get this to fully work on the non-pro version?

scatman75 commented 3 years ago

Would be really good to have a guide that is describing the process in total. I personally struggled with the selection of all neccessary kernel modules at first. After reading this page and some other sources I managed to get an openwrt version 19.07.3 compiled with dlan-plc firmware. The result is unfortunately not satisfactory in relation to PLC. The LEDs of both dlan-devices (1x dlan 1200+ & dlan 1200+ wifi ac) start showing active connections, but after a short period the led of the dlan 1200+ is off and the led of the dlan 1200+ wifi ac is blinking red and in the system log of openwrt the following error is displayed:

im interested in this as per my post, i'd also be interested to understand as to how you flash the unit back to official dlan code.

I doubt that there is an easy way of flashing back the original firmware. I tried flashing the original DVL file from Devolo via the TFTP method but the device was unresponsive afterwards. Nevertheless a new attempt of flashing the OpenWRT firmware went successful. A little digging with an hex-editor showed that the DVL file has at least a custom header and footer. Maybe it would be sufficient to strip off custom header and footer. So I figured that without deeper knowledge of the structure of DVL files this is the bottom line.

You got almost to the goal. Compiling with SETSID support allows for the /etc/init.d/plc script to start the PLC interface (runs plchost process)

What you are probably missing is the PLC Network Key which would be set automatically by the push button pairing. It can be done from shell also. Your PLC settings are stored to /lib/firmware/plc/user.pib

This is what the settings look like after flashing OpenWRT :

Support for the Devolo dLAN pro 1200+ WiFi ac is in the OpenWRT master for target ath79 since this commit. The snapshot image also works with the white, non-pro Devolo dLAN 1200+ WiFi ac variant.

I enhanced the scripts in PLC firmware package @0xFelix made so that setsid is no longer mandatory and one doesn't have to compile the entire OpenWRT from sources.

I'm unaware of any issue the removal of setsid may bring, however if there are any those are likely to be related to push button pairing which may not work and manual pairing as described above with open-plc-tools needs to be used instead.

The OpenWRT PLC firmware package still needs to be build from sources as Qualcomm license doesn't allow distributing the PLC hardware firmware files. After being built those OpenWRT PLC firmware packages can be used for creating OpenWRT images using ImageBuilder without rebuilding the OpenWRT PLC firmware packages.

I added instructions for creating PLC frmware packages and OpenWRT firmware with the PLC firmware packages embedded to my fork of 0xFelix's repository.

Many thanks to @0xFelix for doing the hard work providing the patch for the Devolo dLAN pro 1200+ WiFi ac support.

scatman75 commented 2 years ago

@garyttirn I tried out your scripts and the explanations on your Github site. Everything worked out well and I was able to build a recent snaphot version with included support for PLC. Thank you very much for your ongoing efforts of making the users life easier.

I tried to flash the firmware by the tftp method, but I can't get the Dlan to uboot with 192.168.1.100. I think I tried all the possibilities, even flashing official firmwares down to 1.2.1 Is there another way to flash Openwrt on a non pro Dlan 1200? I noticed someone have been able to get ssh root somehow?

scatman75 commented 12 months ago

Switch off the Devolo device and hold down the reset button when switching it back on (it is best to use a multiple socket). Wait until the Home/WiFi LED has flashed red/white a few times, then release the reset button. Make sure your TFTP server is up and running and the firmware file is named uploadfile in advance.

Bloody hell, it's as I was reading back my post after your comment that I noticed I made a mistake on the IP, with 1.100 instead of 0.100. Thank you for your help!

I'm wondering why it displays [MT2910;X], is it normal if I used a MT2674 pib?

noblemtw commented 12 months ago

The users.pib file is extracted from the device itself, it's showing you've got the MT2910 chipset so I'd try again using the firmware for that chipset. The chipset in my plugs match the sticker, although make sure you check the sticker on the device you are flashing, the wall adaptor is probably different...

It's worth being aware that there's newer firmware available here (The firmware isn't vendor specific, so don't worry that it's a tp-link community site) .You can just drop it into feeds/dlan/dlan-fw/qca/devolo,dlan-pro-1200plus-ac in place of the nvm you have, although probably best to get the basics working first :-)

michelsup commented 12 months ago

Tue Sep 19 09:04:37 2023 user.notice plc: activate PLC Modem

but still no luck. I even tried the new nvm from your post. Pulling a new Ethernet cable will be simpler. Is there a way to debug the modem?

noblemtw commented 12 months ago

I remember having all sorts if issues when I set mine up, the documentation wasn't as good back then and got updated just after I got it all working. I'm pretty sure anything we add here will be of use to other people too...

The plctools you've been using are probably your best bet for debugging, although when I set mine up, I found this page quite useful, and the homeplug script does save having to to remember the syntax for the various commands...

The two potential issues that spring to mind are:

I seem to recall that the plctools default to the wrong interface, so adding export PLC=br-lan to root's profile file is a good idea too.

In fact, having just checked your earlier post, you may have the wrong interface set, /etc/config/plc should look like the below, at least mine does...

config plc 'plc'
    option disabled '0'
    option interface 'br-lan'
    option individual_nmk '0'
garyttirn commented 12 months ago

Yes, ethX would no longer work with fw4, br-lan had to used.

The change is reflected in the default config, but I'm afraid I seem to have missed update to the READMEs.

michelsup commented 11 months ago

Ok, I give up. The modem doesn't want to connect to any of my PLC's. I compiled and flashed a dozen of times, I just have anymore enough energy to try to go back to the original firmware. Thank you for patience and your help.

garyttirn commented 11 months ago

As last resort I'd first stop the plchost using /etc/init.d/plc stop and then check with the plchost-command that the /etc/init.d/plc runs to see what if anything is happening by adding the -v argument as shown below :

/usr/bin/plchost -v -i br-lan -N /lib/firmware/plc/devolo,dlan-pro-1200plus-ac/MAC-7500-v2.8.0-01-NW6__-X-CS.nvm -P /lib/firmware/plc/user.pib -n /lib/firmware/plc/user.nvm.tmp -p /lib/firmware/plc/user.pib.tmp

Parameters depend on your hardware, like the firmware provided by -N argument.

plchost manual in github tells more about options and provides example output: https://github.com/qca/open-plc-utils/blob/master/docbook/plchost.1.html

For the record, I'm running the white, non-pro variant with OpenWrt 22.03.5 r20134-5f15225c1e and just the latest firmware from Develo (v2.8.0) and it connects fine to Devolo dLAN pro 1200+ PoE and Devolo dLAN pro 1200+ single & triple, same firmware version on all adapters.

I'm building my images using Imagebuilder and just including the prebuild dlan-package:

Which version of openWRT are you using? Or are you using the official firmware? If you are using an official openWRT version, I remember that my chip rom got corrupted, I don't know how, and in order to communicate with the plc chip to load a firmware (plchost looks like just tried to load the firmware in memory each time in the original rom instead of updating the firmware in the plc rom), it required a 100MB speed link connection on the switch, which it was at 1G. I didn't know how to change the switch port speed to 100M to communicate with the chip to at least load the firmware and use it again on the official openWRT, so I got stuck there. You may want to check that, see if you can find a way to change the plc port link speed in the switch to 100M and connect to the plc chip. If you find the way, let us know please, I would love to use it again :D

Since plctool works, there shouldn't be anything wrong with the hardware itself.

Have you made sure you have netfilter firewall running ?

It is mandatory as netfilter also handles tasks of former ebtables and plchost communication depends on punting PLC control packets to the host.

root@plc:~# /etc/init.d/firewall status
active with no instances

Now that I come to think of it, the netfilter rules depend of the br-lan and PLC interface MACs and this could be incorrectly detected by /etc/init.d/plc-script.

This is what MACs and netfilter rules look like on my devolo dLAN 1200+ wifi ac, netfilter tables need to be properly populated with the br-lan and PLC-interface MACs and this is done by the /etc/init.d/plc script. The MAC for the PLC interface is only present in the pib and kernel doesn't see this interface, thus the punting to plchost via netfilter was needed.

If I interpret it correctly, netfilter is not the problem...

There is a rule for MAC ...5D:DB, but ...

... this doesn´t look correct for me.

Also i only see one adapter, if i call plctool on my server (while the OpenWRT adapter is reachable by TP, too).

Have you tried with individual_nmk set to 0, thats what I have on my working system. I'm not entirely sure what the setting does, but it feels like you should have the same network management key set on all devices...

The nftables rules look correct, first line is some sort of default mac that the devices use on boot, while 2nd and 3rd line should be the mac of the powerline and ethernet interfaces of the device and my devices at least, the powerline mac is the ethernet mac+1...

The plcstat output looks odd as the local and remote mac addresses are totally different, could you have accidentally duplicated the plc mac on more than one device, that could also explain why it's not working.

Pairing got lost, of course - but server doesn´t see devolo dLAN 1200+ WiFi ac [MT2673;X] anymore:

If i turn on the dLAN 1200+ WiFi ac now, the Powerline Button is just red and nothing else happens. I think i can still use the TFTP Methode to flash a new image, but i have the feeling, that i need a different image. Do you have any advice? can i use the OpenWRT Luci to flash the stock firmware?

First of all, this is not a general discussion forum, this is a specific issue and should only deal with this topic.

Nevertheless, regarding your problem: You have to press the reset button (inside the small hole) for several seconds while (!) supplying the Devolo with power. The TFTP server must be running on IP 192.168.0.100, reachable by LAN and provide the file "uploadfile" (rename the image).

From https://openwrt.org/toh/devolo/dlan_pro_1200_wifi_ac: - the image on the TFTP server must be called “uploadfile” - setup your TFTP server to use the IP address 192.168.0.100/24 - connect an ethernet cable between your computer and one of the LAN ports - power it up while pushing down the reset button - wait until Home/WiFi-LEDs blink red/white a few times and stay on, then release the reset button - wait until LEDs stop to blink red/white - the device should boot now

New attempt, from the beginning... Stock firmware on both devices, reset to factory defaults and paired by pressing the buttons. devolo dLAN 1200+ [MT2639] connected to switch by TP, devolo dLAN 1200+ WiFi ac [MT2673;X] only connected by PLC. plctools running on Ubuntu build server (vTest01):

Did you get anywhere? I am trying to add an OpenWRT DLAN 1200+ ac (MT2765) to an existing network of x2 identical adapters, I can see the network, copy the NMK and successfully restart plc but I don't get the adapter coming online.

I've built the dlan packages from the feed and compiled a v23.05.4 image for devolo_dlan-pro-1200plus-ac, with the dlan-fw-pro-1200plus-ac, dlan-plc and various open-plc-utils items.

No, I have given up until further notice.
