Wolfson modified Noobs raspbian zipped img  Cannot unzip new download

Please make the md5 checksum for this file available.

Thank you

Patrick

I have kept my original download, but I have downloaded the zip file again to compare them.

I'm running WinXP with Cygwin.

My old download from Feb 26 and today's are identical.

$ ls -ltr *wolfson*zip
-rwx------+ 1 ragnar Ingen 4713117059 Feb 26 12:16 wolfson_3.10_master.zip
-rwx------+ 1 ragnar Ingen 4713117059 Mar 17 21:12 new_wolfson_3.10_master.zip
$ md5sum wolfson_3.10_master.zip new_wolfson_3.10_master.zip

72d091a9b43e47a5b7b85432ec15611c *new_wolfson_3.10_master.zip

WinZip complains - "Archive is greater than 4 gigabytes."

WinRAR complains - "! ... wolfson_3.10_master.zip: Either multipart or corrupt ZIP archive"

Command line unzip complains - "warning [wolfson_3.10_master.zip]: 418149653 extra bytes at beginning or within zipfile...error [wolfson_3.10_master.zip]: start of central directory not found;...

7-zip works, it extracts the image OK.

There are Linux and OSX versions of 7-zip available at http://www.7-zip.org/download.html

I think we all get a lot of stack traces at boot. It's even mentioned in the Soundcard Manual:
"You may notice 'trace errors' during boot up. These are regarded as harmless, and they will not appear on future releases."

Not saying that you don't see real, fatal errors, though.

3.10.36, is that the "stable" 3.10.y or the "next" 3.10.y-next branch?

>I think we all get a lot of stack traces at boot. It's even mentioned in the Soundcard Manual:

I see the stack-traces in 'dmesg', but they don't stop the card working. And if they are going to disappear in future releases I don't see them as a problem.

I'm not positive Ragnar.  I'm just getting them via the rpi-update.  My uname -a looks like:

Linux raspberrypi 3.10.36+ #662 PREEMPT Fri Apr 4 18:31:16 BST 2014 armv6l GNU/Linux

OK, that's the stable branch then. You have to explicitly tell rpi-update if you want the "next" (a.k.a. "bleeding edge, use-at-your-own-peril") branch.

Pulling sources from github now...

... and Wolfson's patches didn't apply cleanly.

Apparently there's been work done to add support for a new SoC DAC.

I'll try to patch by hand. Always fun

EDIT: Wouldn't you know... we're keeping with the theme of this thread. Command line unzip was unable to unzip the kernel source Zip-file

Apparently a bug in Linux unzip that pops up when you have many symbolic links with long path names in the archive. 7zip to the rescue again!

Ragnar

Nope, too much stuff has happened in sound/soc/codecs/wm8804.c between 3.10.25 and 3.10.36.

I'm not familiar enough with that code to make an attempt.

I've made an update/upgrade test run. Fresh install of the Foundation wheezy 2014-01-07 image (i.e. not NOOBS), raspi-config, apt-get update, apt-get upgrade and rpi-update.

End result: 3.10.36+ #662 PREEMPT Fri Apr 4 18:31:16 BST 2014 armv6l and all the latest firmware.

I then applied my patch archive, i.e. downgraded the kernel to 3.10.25.

And it works... I can play and record.

No idea why it won't work for some of you.

Hello,

Thank you Ragnar, I did the same that you explained in the prev posts and my wolfson worked flawlessly (only playing audio right now).

Yesterday I download the Foundation Raspbian, upgraded and updated everything, the latest kernel WAS 3.10.36+ #664, I followed

your instructions on going back to kernel 3.10.25 with the smaller package you provided, and it work just perfect.

I'm happy listening to some loseless flacs via MPD on the Pi and mpc/auremo/mpdroid as clients.

Thanks again, bye, Diten.

I just booted up Raspyfi, the precursor to Volumio, using Ragnar's Wolfson replacement kernel. It all seems to work. The Wolfson card is recognised, and I can play music out through the SPDIF out. Presumably the same approach would work for Volumio too.

Hi Jan,

I wanted to try Rune Audio but I am newbie in linux.

Any tips on how to run rune with wolfson ?

Thanks

You can try to use my patch for runeaudio

Patch contains a modified kernel with modules and other supporting files, including the necessary changes in runeaudio

It also includes support for hw and safe shutdown poweroff module, described in another post.

Hello Jan,

would you be able to advice how to compile the patch? I am not very familiar with and new to Linux.
