Anyone getting this line?
Can anyone upload a healthy log file?
Thanks.

Sorry, my Syslog was flooded by other repeated warning message, so no “normal” syslog for you.

I think the message is complaining about the 2 Wi-Fi data files are missing.

Can you check the 2 data files are located under the directory “/etc/wireless/mediatek” first ?
( mt7981.dbdc.b0.dat & mt7981.dbdc.b1.dat )

In a healthy boot I have those files

However, as soon as I restart the healthy boot I enter in a loop of restarts.

It seems our files are different in (date, size) ?
Can you check the ‘uname -a’ command to see if we are in the same firmware ?

FWIW, I’ve got the Nov 29 date, so yours may be the oddball, @cafebug.

(also FWIW, I got mine before Nov 29, and the current firmware came out Dec 5, so I have no idea what the Nov 29 date actually represents.

defibos · 2022-12-20T20:39:33.951Z

My guess is that race condition during boot causing sometimes a failure because some files are not located. I attach 2 log collections:

fully healthy boot:
logread healthy.zip (27.6 KB)

several attempts with failures and a final sucess:
logread error and healthy (several attempts).zip (42.8 KB)

Probably compiled 29 Nov and released 5 Dec. They usually have a few days/1 week delay for stability checks.

I think they are not fully consistent with versioning for beta releases during the beta testing, that is why we have the 26Oct and 29Nov for 4.1.2. That is why it makes sense to add the md5/sha256.

Compile time shows as 12/5 though, not release time.

Did you modify the /etc/wireless/meditak/ files?

jdub · 2022-12-20T21:48:29.413Z

No. I’m assuming the ones with the timestamps of basically now are auto updated by the OS.

cafebug · 2022-12-21T05:14:46.716Z

Well, I don’t touch any Mediatek file.

alex_zheng · 2022-12-21T09:17:01.525Z

Could you get some tools like PL2303 to get the sys log during startup(need to open the case )?

defibos · 2022-12-21T09:34:14.376Z

Hi,
I changed the log file to the external usb drive.
The log files attached above contain the logs with reboot attempts and a few successes (I logged to luci in the successes, which is logged).
I think the issue is related to the files described above not being found during the boot process.

What part is missing? Last line before crash?

JerryZhao · 2022-12-21T09:56:16.501Z

This is not the reason of reboot.
Could you connect UART to your router?

I have to order one.
It can take some days before I get the unit. Is there I can do meanwhile?

alex_zheng · 2022-12-21T10:11:56.689Z

I double Checked the log file. And there is no useful information for reboot problem. So I doubt whether it reboot or not.
Could you please tell me what phenomenon that make you think it rebooted?
Our engineer is also help to confirm the log file.

defibos · 2022-12-21T10:15:12.687Z

When you plug the device the lights start to indicate activity and the wifi networks appears after 20/30s. A few moments after that lights turn off and the cycle starts again.

alex_zheng · 2022-12-21T11:05:22.194Z

Thank you for the addition info . So maybe the device is not reboot. we wonder if the LED behaviour is wrong when the network is in the rebooting loop.
So the device is always in the loop or you need to do something to trigger it ?
Any device is pluging on the Beryl AX ?
Please forgive me so many questions, because I want to know more details

alex_zheng · 2022-12-22T10:39:18.599Z

Could you please to help to update the info ?

defibos · 2022-12-22T12:23:13.758Z

The device is not always in the reboot loop. Sometimes after plugging the power it boots correctly, but after a few minutes (2-20 min) it reboots itself and enters a rebooting loop.
Sometimes when the power is connected it enters the reboot loop directly without any successful boot.

I attach a video with the led lights pattern. The first boot is ok, but it reboots itself and enters a reboot loop.

Beryl ax reboot problem

I tested with/without usb connected, with/without ethernet cable connected, with/without repeater configured, as AP with cable in WAN and after factory reset and uboot flash. Same results. Only some differences until the reboot cycle is started.
