Hello people,

 

Trying to use an af9015-based USB DVB-T tuner (Leadtek WinFast DTV Dongle Gold), which used to work perfectly on OpenPLi 2.1, and OpenPLi 3.0 until recently.

 

After an online update, the box doesn't boot anymore. Dmesg says:

Please point me in the right direction, to make it work with actual image version.

I don't know much about this, but have you tried to boot without the DTV dongle?

[rhinoceros]

Interesting. I posted a similar issue in the dutch part of the forum. I have a USB DVB-T Nova-T stick. Since recently, probably since the upgrade to 3.8.7 kernel my box (ET9X00) hangs with 'Booting...; in the display. The stick is detected and registered but seems to fail initialization. Yet exactly the same configuration has been working without any such issue now for two years.

 

Are there others that have issues with boxes that do not boot with the recent kernel update? If so, which USB devices do you use - if any?

[robertut]

I don't know much about this, but have you tried to boot without the DTV dongle?

 

Yes. Without the DTV dongle plugged in, the box boots up successfully.

 

It worked perfectly until a recent update. The DTV dongle is not faulty, it works perfectly on a PC.

[robertut]

Since recently, probably since the upgrade to 3.8.7 kernel my box (ET9X00) hangs with 'Booting...; in the display.

 

Is there any way to actually downgrade back the kernel to an older version which still works?

[Erik Slagter]

By the way, this is a KERNEL OOPS. Most of the time this means a bug in a driver (in this case indeed the USB stick).

[robertut]

Hmmm... how can it be a bug in the af9015 driver, while in earlier kernel versions worked perfectly with the same driver, moreover, on OpenPLi 2.1 it still works just fine! With the same driver.

you are contradicting yourself
The driver is included in the kernel, so a different kernel version means a different driver version.

[robertut]

I thought that the driver is being installed from the plugins manager download menu, from the "driver" category. If that's not the driver, what is it then? I'm asking because the box works fine even with the DTT stick plugged in, until I install the (so-called?) driver from the plugins menu. Does the kernel change during this process?

 

Installing is required because otherwise it couldn't be seen in the tuners list. After install completes, a reboot is required, and the box hangs during bootup.

Strange because the dib0700 driver seems to have the same issue. Box hangs only sometimes in booting. That is then 2 drivers broken. Perhaps a change in the driver interface in kernel 3.8.7?

You assume, by the fact that driver is loaded as a module, that the driver is a seperate entity from the kernel. Your assumption is wrong. Modules are pieces of the kernel that aren't loaded by default. Every module is different from kernel to kernel version.

No, the issues have no relation.
This one causes an oops, while yours is a timing issue during init.

[robertut]

OK. I understand.

 

Another question then.

 

I have a couple of older OpenPLi images saved on my PC, like for example "OpenPLi-3.0-beta-et6x00-20130316_usb.zip". I used to have this version running perfectly with my af9015 DTT stick until I made an update.

Now I took this 20130316 image, flashed it back - installed driver from online feed, and the box crashed. I don't understand why... Could somebody explain me?

 

Was the af9015 package on the server feed changed since 20130316, when it was still functional with the images with kernels available at THAT time?

 

I'd be happy to restore the functional state with my fresh 20130316 image I saved back then, and the af9015 package + its dependencies which were available back then...

Edited by robertut, 21 July 2013 - 20:11.

[betacentauri]

The image uses most likely an older kernel. Drivers or better modules are build against a kernel version. So you try to use kernel x with driver for kernel y. That don't work.
It seems that the feed contains only the latest versions.
Don't you have an old fullbackup which you can use? (Always make one, then you don't have these troubles)

[robertut]

Unfortunately I don't. I only have a backup of OpenPLi 2.1, which I had to revert to now...

That's why I'm seeking for help.

 

Could anyone please give me at least some version numbers or file names of older af9015 modules in .ipk format? Hopefully I can find anything on some forums...

when you install the drivers from the feed, the kernel is updated (as a dependency).
You need a 3.8.7 kernel in order to install a 3.8.7 driver

Was the af9015 package on the server feed changed since 20130316, when it was still functional with the images with kernels available at THAT time?

Yes, the af9015 package version is 3.8.7 now, because it is part of the kernel.

[robertut]

Is there a place where I could find older package versions I could manually install with opkg on older image version?

[Erik Slagter]

Yes, actually you would need both the older kernel and the corresponding modules, which might be difficult, as the kernel is in the image and the modules are in the feed (which are not archived).

[betacentauri]

Try this one. Do you need other modules, too?

Wow, thanks a million! I'd love to have the dependencies of this, too.
