WL500W-1.9.2.7-rtn-r2324.trx from core.dumped.ru has bricked my WL500W #171

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. download the packed firmware from 
ftp://core.dumped.ru/rt-n/2324/wl/WL500W-1.9.2.7-rtn-r2324.trx.gz
2. unpack the file WL500W-1.9.2.7-rtn-r2324.trx
3. start an upgrade with the FW vesion r2324 from the WL-500W web interface

What is the expected output? 
WL-500W working with the FW r2324

What do you see instead?
"bricked" WL-500W: all ETH activity LEDs are blinking, Power and AIR LEDs are 
off. Device enters the recovery mode by pressing the reset button.

What version of the product are you using?
WL-500W with FW r2308 (working) and FW r2324 (bricks the device).

Please provide any additional information below.
Programming the FW r2324 by TFTP has shown the same behaviour. Downgrade to the 
FW r2308 (previous version used on the device) gets the device back to life. I 
undersand, that the firmwares from ftp://core.dumped.ru/ are experimental. This 
Issue is for your information only, guys.

Seems to be, something strange happen with core.dumped.ru build environment. I 
can't reproduce problem on my self-compiled r2324 on WL500gP (I don't own 
WL500W).

Can you compile FW yourself? Have you serial console?

Hi lly,

yes, I have a serial console. But I fear, I'm "too stupid" to compile thе FW 
by myself. Or better to say, I never did that before. Will it help, if I'll 
look for mesages over the serial interface in the "bricked" state?

Regards

Serial console should show message of the death. But in case of some problem on 
build env. (do you remember that core.dumped.ru is not under our control), this 
can be useless. 

Anyway, did you try r2314?

GoogleCodeExporter commented 9 years ago 
Honestly, I don't know under whose contol is core.dumped.ru :-[

But in any case, I want to help if I can. I didn't try r2313, r2314 and r2322. 
What shall I better do? Shall I try one of these releases? Or shall I wait for 
the next release and try it?

"Unlimited" from wl500g.info forum create core.dumped.ru resource for public. 
Big thanks to him for that.

As you wish. Typical cause of the "brick" (I don't like this word, since 
built-in TFTP still work) are in kernel - in your case it _might_ be r2318.

OK, then I'll wait for the next available release on core.dumped.ru an try it.

The only patches from r2318 commit which can break normal boot is:
 164-timerfd1-newapi.patch  
 164-timerfd2-fs.patch

but I still can't get stable reproduction of problem/bug.

today I've flashed the new r2326 (WL500W-1.9.2.7-rtn-r2326.trx) with the same 
result: device doesn't come up, all ETH activity LEDS blink.

Serial console repeats the same output cyclically. I've logged two cycles, see 
attached text file

Some kind of induced problem :(

Can you attach console log of successful boot on your 500W?

Original comment by lly.dev on 10 Nov 2010 at 7:32

GoogleCodeExporter commented 9 years ago 
OK, I will give you a normal boot log today evening. I've already restored my 
device with r2308 again. I could also try to find out, which is the first 
release with this bug (between r2308 and r2324), but I need a little bit more 
time for that.

Problem appeared on MIPS32R1 devices only (WL500W, WL500gP) and IMHO caused not 
by some commit text itself. Problem either in serial initialization code for an 
old devices (RT-N16 works well), or it is gcc optimizer bug.

I have the similar problem with WL500W-1.9.2.7-rtn-r2326.
I have attached the log file which captured from console with some cycles of 
booting. I hope it can be helpful. Thanks.

OK, just in this moment I hold a screwdriver in the hand and want to open my 
WL-500W and to get the successiful boot log. Goot timing, then I don't need to 
do that :)

Hi,

today I tried all releases through. r2314 is the last working release, from 
r2322 and higher my WL-500W does cyclically reboot. Maybe that will help to 
lokalize the bug.

regards

Unfortunately, problem reproducible not with 100% and even debugging printk's 
often hide the bug. r2318 isn't buggy, it only uncover an old bug.

I tried to fix problem in r2332 (should fix some potential races), but it might 
be additional patches needed.

How can I test it? Should I wait on the next release on core.dumped.ru?

As usual, you have at least two choices:
1) compile FW yourself
2) use night build from core.dumped.ru

Original comment by lly.dev on 13 Nov 2010 at 7:03

GoogleCodeExporter commented 9 years ago 
OK, I'll wait for the next build.

r2334 already on core.dumped.ru.
Anybody yet was tried it on WL-500W?

I tried r2334 just now. Seems to work! lly, thank you very much!

In case of similar problems just reopen this issue.
