Topic: ZyXEL NBG-419N v2 support

The content of this topic has been archived between 27 Nov 2017 and 28 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Hello,

I purchased new version of ZyXEL's NBG-419N.

The v2 version of the device looks identical to its predeseccors, and is *almost* able to boot AA and BB rc-3.

The kernel boots up nicely, but hangs to:

[    0.560000] VFS: Cannot open root device "(null)" or unknown-block(0,0)
[    0.570000] Please append a correct "root=" boot option; here are the available partitions:
[    0.590000] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

BB rc-3 however goes a bit further, producing only one additional line:

[    2.520000] rt305x-esw 10110000.esw: link changed 0x01

I flashed AA once, but restored to stock FW due to crash.

The boot logs are produced by loading the image to SDRAM by tftp and executing it, by choosing '1' from ZyXEL's u-boot menu.

Could there be something to do in order to run AA or BB on the device?

The CPU architecture seems to be correct:

Just for test you can try BB image for dlink dir-620 d1.

Hello,

and thank you so much for your quick reply.

I'm sorry, but it didn't work.

BB image for dlink dir-620 d1 booted, but didn't do more than produced a bunch of filesystem error messages, before crash:

However, by performing some additional searching, I found out that you are the man who already solved the problem some time ago.

According to the thread https://forum.openwrt.org/viewtopic.php?id=40634 a custom build for NBG-419N v2 was made, nbg-419nv2-sysupgrade.bin (and can still be downloaded)

I can confirm that the custom build can be flashed on the device, and it boots up nicely.

But, regarding the thread, some patches were needed from ZyXEL in order to produce the working image?

However, I understood that NAND would be supported on BB by default?

Can you Serge recall how this custom build for v2 was made?

Also, with some googling, I found some posts regarding v2 patching, but I guess these are not valid anymore, as I got the impression that the OpenWRT build system has changed quite a lot.

http://pastebin.com/raw.php?i=Su918N9r

In addition, I also found something related to custom mtd layout: (at the very end, but not for v2 though)

http://ranosgrant.cocolog-nifty.com/ope … k-wnh.diff

I really don't know whether or not these are still valid, or how to implement these in order to produce a specific build for v2, but could someone please have a look once more, as Serge already succseeded producing a fully working image?

Only for building factory image which may be flashed form original Zyxel firware.

Can you Serge recall how this custom build for v2 was made?

That patch was simple and incomplete (flash layout, factory image, wifi eeprom, leds and buttons) because of tester inactivity.

Also, with some googling, I found some posts regarding v2 patching, but I guess these are not valid anymore, as I got the impression that the OpenWRT build system has changed quite a lot.

Yes. Starting from BB no need to recompile kernel to add new device.

New test images
https://yadi.sk/d/1ZV0lKJwbTE65
Some comments:
1. AA image use custom kernel, so AA-release repo compatibility is lost (kernel modules may crash). But quick and stable smile.
2. BB image is fully compatible with BB rc3 repo.
I put dts-file. You may correct it and make new version of images for test.

Hello,

And thank you so much for your quick reply.

The AA build acts exactly as you said, i.e. kernel modules indeed do crash:

I'm not quite much a programmer, but I'll have a look about the .dts -file. I guess the least what I can do is to modify the mtd -layout, as in /proc/mtd. Might as well need to change something else to have the image itself produced?

I think that something wrong in your firmware installation procedure:
1. AA custom don't use rt2800pci module but in your log it presents in crash dump (my build use compat-drivers-2014-05-22 for wifi).
2. BB cann't find start of flash free space.
It looks like  old rootfs is used (from previous firmware installation).
How do you install firmware exactly? Serial console or emergency recovery?

Hello,

Yes, you're correct.

Instead of flasing the image directly to the device, I tested it first by loading it to SDRAM, by choosing '1' from the u-boot menu.

Apparently, this was not the correct approach.

By choosing '2', and confirming the action by responding 'y' to flash the image, I can confirm that both of the images do work.

And yes, I do have a serial console; I performed all the tasks over the serial console.

Could these patches/settings you made be included in BB, in order to have images for v2 in the future?

Thank you so much for your time, help and assistance. You're very kind.

Before send patch to developers I'd like  you to do some additional check:
1. leds and buttons (I take it from v1) works in v2 correctly.
2. Does v2 have usb-port populated? In my dts-file it's enabled by default.
3. Wifi work as expected.
And now you can test BB rc3 without restriction, AA with possible crash of AA repo kernel modules.

1. leds and buttons (I take it from v1) works in v2 correctly.

Leds do work as expected;

LAN & WAN leds go on and off when connecting/disconnecting a cable, and blink during traffic.
Wifi led goes on & off when enabling/disabling Wifi via LuCI.
Power led blinks during boot & FW flash. Stays on after boot is completed.

Some of the buttons do not work as expected;

The LED button works, but it's only function is to turn off all the leds.

WLAN button does not work at all. It's function is to switch Wifi on and off, but nothing happens.
Wifi can be enabled/disabled via LuCI regardless of the button position.

WPS button may not work. (And I have no means to test it, and I guess it's never implemented to OpenWRT?)

2. Does v2 have usb-port populated? In my dts-file it's enabled by default.

It does. By inserting a usb stick to the port, a message is displayed to console, as well as logged to syslog:

[  391.720000] usb 1-2: new full-speed USB device number 2 using ohci-platform

[  391.960000] usb 1-2: no of_node; not parsing pinctrl DT

And that's all what happens.

3. Wifi work as expected.

Wifi works as expected;

Wifi can be configured via LuCI, and a wireless device can receive an IP -address.
The status of the connected wireless devices can be seen on LuCI.

And now you can test BB rc3 without restriction, AA with possible crash of AA repo kernel modules.

Thanks, but I guess I'll stick with BB.

Kindly let me know if any additional information is needed. I'll do my best to help, and I'll reply as fast as I can.

Update:

I booted the device, and during the boot it asks you to specify debug level. I chose '4'.

After boot, by pressing the WPS -button, the following information is displayed:

Nothing is printed if you press WLAN or LED button.

I used BB all the time.

Base image need additional kernel modules to mount stick. So opkg update && opkg install,
at least kmod-scsi, kmod-sd_mod, kmod-usb-storage, kmod-fs-vfat, kmod-nls-cp1251 ( for me:))

leds:
"power" - defined - works
"wps" - defined - ?
"wifi" - define - works
Any other leds? usb?

Current state of leds and buttons

cat /sys/kernel/debug/gpio

To check gpio if unreserved (e.g. gpio7)
for led:

echo 7 >/sys/class/gpio/export
echo out >/sys/class/gpio/gpio7/direction
echo 1 >>/sys/class/gpio/gpio7/value

for button:
"in" to direction and see high/low current state while pressed/released
Good luck!

Base image need additional kernel modules to mount stick. So opkg update && opkg install,
at least kmod-scsi, kmod-sd_mod, kmod-usb-storage, kmod-fs-vfat, kmod-nls-cp1251 ( for me:))

Thanks. I installed the packages, and it worked like a charm. The system deteced the usb stick as in any other linux, and I was able to mount it.


Regarding the leds: (from left to right, all leds in front panel)

power    - works
lan[1-4] - works
wan      - works
wifi     - works
wan      - works
wps      - does not work
usb      - does not work

Buttons:

reset    - works; resets the device (and reboots)
wps    - the system is aware of the button, but nothing happens when pressed. (Debug dumps some info, however)
wlan    - is 'rfkill', as you already guessed. Nothing happens.
led    - I'd say is nothing more than a hardware button.

No any other buttons.

And pop; the usb led is on.

Which after

Turns off the usb led.

No affect in any other leds - reagrdless of the state of the buttons.

Of which 13 is the usb led.

Enabling/disabling wifi via LuCI turns wlan led on/off (as well as the wifi itself....).

So, it's 12.....?

Next test version
openwrt-ramips-rt305x-nbg419v2-bb-rc3-squashfs-sysupgrade.v4.bin - added /etc/rc.button/wps script as sample (without real function, only on/off wps led), added rfkill button.
BTW, wlan buttton has fixed position?

Hello,

LED and WLAN buttons both have fixed positions, so I guess those should be called on/off switches instead... wink

A picture can describe more than a thousand words:

RESET push button, WLAN & LED on/off switches:
http://www.zyxel.ch/assets/global/image … 2_7305.jpg

WPS push button:
http://www.kiwi-electronics.nl/image/ca … 00x533.jpg

The script for wps button does not work correctly. To test, I changed it to:

#!/bin/sh

logger "${BUTTON} is ${ACTION}"

#if [ "${ACTION}" = "released" ] then 
#       echo 0>/sys/class/leds/nbg-419n:green:wps/brightness
#else 
        echo 1 >/sys/class/leds/nbg-419n:green:wps/brightness
#fi 

which turns the led on, (but not off anymore).

Now the rfkill button need to pressed a few times before wifi stays enabled. (I guess the script interprets it as a push button.)
LuCI is also able to determine the wifi status.

However, it looks that if wifi was enabled, then it will be enabled after reboot, even the button is switched to 'OFF' position (in the u-boot section).
By switching to ON first, and then OFF, the wifi will be diabled again.

The usb led does not lit if a usb stick is inserted to the usb port.

openwrt-ramips-rt305x-nbg419v2-bb-rc3-squashfs-sysupgrade.v5.bin - fixed wlan switch I hope

Hello again, and thank you.

openwrt-ramips-rt305x-nbg419v2-bb-rc3-squashfs-sysupgrade.v5.bin - fixed wlan switch I hope

I performed the following group of tests:

Power off the device. Switch WLAN button to 'OFF' position. Connect power. Wait boot to complete. Switch WLAN button to 'ON' position.

It works fine.

Then,

While still powered on, switch WLAN button to 'OFF' position. Wait a sec. Switch WLAN button to 'ON' position.

So, the button works as it's supposed to work. Jumping is a minor issue, and can only be seen on console.

Now, if you want to be perfect, and nothing more than absolutely perfect, and you're most certain about it, keep reading. Otherwise, please close your eyes and hide from the evil world.

And, don't blame me. smile I don't work here. smile I have family to support. smile I'm (still) too young to die. smile

However, to test it in a bit more detail, I performed the following tests in order, while keeping the device powered on:

Turn Wifi OFF via LuCI, while button is set to 'ON' position. -> Wifi changes to 'disabled state'.

Switch WLAN button to 'OFF' position. -> Wifi stays at 'disabled state'.

Turn Wifi ON via LuCI, while button is set to 'OFF' position. -> Wifi changes to 'forwarding state'.

Switch WLAN button to 'ON' position. -> Wifi changes to 'disabled state' before returning to 'forwarding state'. (As in dump above)

Turn Wifi OFF via LuCI, while button is set to 'ON' position. -> Wifi changes to 'disabled state'.

Switch WLAN button to 'OFF' position. -> Wifi stays at 'disabled state'.

Turn Wifi ON via LuCI, while button is set to 'OFF' position. -> Wifi changes to 'forwarding state'.

Turn Wifi OFF via LuCI, while button is set to 'OFF' position. -> Wifi changes to 'disabled state'.

Switch button to 'ON' position. -> Nothing happens. <--- BUG

So, there's some logical error.

I guess the only way to solve this would be reading the state of the WLAN button from registers, and act accordingly.

In my opinion, the WLAN button state (on/off) should be honoured over LuCI. I.e., if the WLAN button is switched to 'ON' position, then, and only then the wifi could be disabled/enabled via LuCI, and with command-line tools. Otherwise no. Also, regardelss of the situation, if the WLAN button is switched on, the wifi should be enabled as well.

Update:
I rebooted the device while WLAN switch set to 'OFF' position, and chose '4' as debug level.

When switching the WLAN to 'ON' position, the following information is dumped to console:

Sorry, I was out for some days. Now I'm back.
But returning to our rams...
All scenarios of use wlan-button may be simply inplemented in userspace and don't concern kernel configuration. I prefer software (Luci) way. As example think of case where no physical access (only remote access) to device.
And finally if all works I'll make patch in two or three days.

Hello,

no problem at all. I hope you had time to relax, and fun.

In my opinion, everything works as supposed, except the USB led. It does not lit if something is inserted in the USB port.

However, and still, in my opinion,

As example think of case where no physical access (only remote access) to device.

Possess a security risk. Anyone having a remote access to the device, may turn the wifi on, regardless of the switch.

But let's not make a big issue about this one. It's enough that people are aware of such possibility.

Hmm..usb led...
Just install kmod-ledtrig-usbdev
Or
openwrt-ramips-rt305x-nbg419v2-bb-rc3-squashfs-sysupgrade.v6.bin - kmod-ledtrig-usbdev added

Hello,

and sorry for a bit late reply. Had some problems with the computer itself...

Just install kmod-ledtrig-usbdev

Won't work ??

root@OpenWrt:/# opkg install kmod-ledtrig-usbdev
Package kmod-ledtrig-usbdev (3.10.49-1) installed in root is up to date.
Collected errors:
 * pkg_get_installed_files: Failed to open //usr/lib/opkg/info/kmod-ledtrig-usbdev.list: No such file or directory.

???

openwrt-ramips-rt305x-nbg419v2-bb-rc3-squashfs-sysupgrade.v6.bin - kmod-ledtrig-usbdev added

Does not work either.

In additition to this, I installed i.e.

opkg update
opkg install kmod-scsi-core kmod-scsi-generic kmod-sdhci kmod-fs-vfat kmod-usb-storage kmod-usb-storage-extras kmod-usb-core kmod-usb-ohci
opkg install kmod-nls-cp437 kmod-nls-iso8859-1
opkg install bash 

as usual, and the USB stick works, but the led won't lit.

Please, check that ledtrig-usbdev is loaded. Then show /etc/config/system and
cat /sys/class/leds/nbg-419n:green:usb/trigger
cat /sys/class/leds/nbg-419n:green:usb/device_name

Must be:
- system contain something like

config led 'led_usb'
option name 'USB'
option sysfs 'nbg-419n:green:usb'
option trigger 'usbdev'
option dev '1-1'
option interval 50

config led 'led_wifi'
option name 'wifi'
option sysfs 'rt2800pci-phy0::radio'
option trigger 'netdev'
option dev 'wlan0'
option mode 'link tx rx'

- trigger [usbdev]
- device_name "1-1"

Else
echo "usbdev" > /sys/class/leds/nbg-419n:green:usb/trigger
echo "1-1" > /sys/class/leds/nbg-419n:green:usb/device_name
(usb led must work upto reboot)
add upper code to /etc/config/system and reboot if not present. (usb and wifi leds will work after reboot)

I hope it fix the problem.

Why the usbdev is in brackets....?

echo "usbdev" > /sys/class/leds/nbg-419n:green:usb/trigger
echo "1-1" > /sys/class/leds/nbg-419n:green:usb/device_name

Produced nothing. The led won't lit.

I tried everything with both, v6 and v7, including several boots, even with the USB stick in during the reboots.

Change "1-1" to "1-2".

Hello,

I can confirm that the suggested methods work; the usb led works as expected.

Insert a USB stick and issue:

root@(none):/# echo "1-2" > /sys/class/leds/nbg-419n:green:usb/device_name

and the USB light is lit.

Now, remove USB stick, and the led turns off.

Insert the USB stick again, and the led is lit.

In '/etc/config/system', change:

config led 'led_usb'
        option name 'USB'
        option sysfs 'nbg-419n:green:usb'
        option trigger 'usbdev'
        option dev '1-1'
        option interval '50'

to:

config led 'led_usb'
        option name 'USB'
        option sysfs 'nbg-419n:green:usb'
        option trigger 'usbdev'
        option dev '1-2'
        option interval '50'

and remove the USB stick and reboot.

After the reboot, when inserting a USB stick, the usb led is lit, as well as turns off upon removal of the stick.

Done. Thanks.
Have a nice weekend.
