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.

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

Sadly, 7-zip on macos 10.7.4 fails to open the file as well. "Keka" fails with the following error:

Extraction of wolfson_3.10_master.zip failed

Error code 2 using "p7zip"

Fatal error

In the absence of any customer support whatsoever from Element14/Newark and Wolfson Microelectronics I guess I'll just try downloading the next macos version of 7-zip from http://www.7-zip.org/download.html

This product - the audio card -  sure is Mickey Mouse! Can it be that the it requires windows in order to work? It would have been helpful if they had said that up front.

I just want to use the card that I paid them good money for.

Thanks, Ragnar and Benjamin

I'm home sick with the flu.

I got bored.

So I decided I would try to make a smaller zip file for you.

I have downloaded the Raspbian install image (2014-01-07-wheezy-raspbian.zip) from www.raspberrypi.org and patched in the Wolfson drivers.

I burned the patched image to an SD card, booted from it and went through the Raspbian set-up procedure.

Rebooted and... It works There is sound from the Wolfson card!

I have zipped the patched image and uploaded it to my Google Drive:

https://drive.google.com/file/d/0BzIaxMH3N5O1RUdSa19od1ltTjg/edit?usp=sharing

The file name is 2014-01-07-wheezy-raspbianW.zip, size is 801 MB.

md5sum 04c5fc96d196c6dc32c2bf1ad57c0124

I hope I have set the sharing permission right for you to access it.

Note: this is the stock Raspbian image, except for the kernel. The music player and extra programs needed are not installed.

sudo apt-get install lxmusic xmms2 xmms2-plugin-all volumeicon-alsa mpg123 mplayer

The use case scripts are there in the folder /home/pi/use_case_scripts

EDIT: I forgot to mention that the stock kernel from the Foundation is present in the image too.

It's in /boot/kernel_original.img, so if you want to use that instead, just copy it over /boot/kernel.img:

sudo cp /boot/kernel_original.img  /boot/kernel.img

To switch back to the patched kernel:

sudo cp /boot/kernel_wolfson.img /boot/kernel.img

You rock!

Hi Ragnar,

Hope you are feeling better.

Thanks for the new d/l!!

Fantastic job!!!

IT IS A  PITY THAT  ELEMENT14 or WOLFSON COULD NOT HAVE PROVIDED THIS!

There seems to be very little official support on this card!

regards

Patrick

Hi Patrick,

WRT official support Mike Powell, the element14 Wolfson Audio Card Project Lead, contacted me by email, and is looking into why the file is unpackable by (some) OS X users.

So there is official interest in solving the problem. Hopefully he and his people will get to the bottom of it.

Thanks to Laura Moore at Wolfson Microelectronics for passing my email on to Mike.

Hi  Geordie.

I first raised this problem on the 15th March

Your post on  March 21st is the FIRST official word on the subject.

On another subject, there are  errors in the instructions regarding compiling the drivers.  I raised this problem on  March 15th as well.

As yet the original version of the  instructions have not been corrected by your "official" support person.

Despite your protestations,  there is NO effective,  timely support,  on this card.

How often does your support person actually read the discussions and offer a solution?

( Looking at the members of this community, I cannot see an entry for Mike Powell)

regards

Patrick

I had to email the PR people at Wolfson to get any response from Element14. Mike Powell emailed me Thursday morning asking for info which I provided but two days later I am still waiting for him to get back to me.

Here is his email to me:

Hello Geordie:

I’m Mike Powell, and was the project lead for the Wolfson Audio Card here at Premier Farnell (= Farnell/Newark/element14).

I’m sorry you are having difficulty unzipping the OS/driver package we prepared. I have organised that, today, we will verify the file is still in good shape by going through the download/unzip process ourselves, again. I have somebody pulling the file down now, and we should have a result later today. If it works, that doesn’t help you, I know, but it will verify the file itself is in good shape.

The file itself was prepared using native Windows 7 compression tools, and unzipped using them too. I also used a number of different decompression tools to decompress the file too, successfully. We also carried out a significant verification exercise on this, and can assure you that the unzip process was designed not to be reliant on Microsoft Windows in any way, but rather a generic format that most OSs could deal with.

Additionally, not to minimise the issues you raise, we’ve seen loads of downloads and successful deployments take place so far.

It sounds like you know what you are doing, so, I’d like to know what platform you are using, and what tools you are using to decompress the file. You mentioned that you have tried this on two platforms – what are they?

We’re looking in to publishing the MD5 checksum as well so that users can verify the download went well.

I’ll let you know later when we have a result on the above, but in the meantime if you could let me know what systems you are using, we can go from there. Once we have you up and running, and have identified the issues, we’ll make sure other users don’t experience the same thing.

Thanks and regards,

I still have the flu.

I'm still bored.

So, I've made a smaller download for you, containing only the kernel, modules and use case scripts.

It's meant to go on top of an existing Raspbian installation.

I have only tested it on 3.10.25 from the 2014-01-07-wheezy-raspbian image. YMMV, No warranties, Caveat emptor and so on...

The archive contains:
boot/kernel_wolfson.img              # The kernel.
lib/firmware/...                     # ... with subdirectories. Firmware for various hardware.
lib/modules/3.10.25_Wolfson+/...     # ... with many subdirectories. Kernel modules.
home/pi/.asoundrc                    # From Wolfson's NOOBS image. Creates a "Master" volume control.
home/pi/use_case_scripts             # Wolfson's and some of my scripts.

The archive doesn't overwrite your current kernel or modules. It does overwrite /home/pi/.asoundrc if it exists. If you have customized your .asoundrc, make a backup of it first.

To install:

• Become root: sudo -s
• Go to root directory: cd /
• Untar the archive: tar xvzf /path/to/where/you/saved/kernel_3_10_25_wolfson.tgz
• Add the line
    kernel=kernel_wolfson.img
  to the file /boot/config.txt
• Reboot

If it doesn't work, you can revert to your original kernel by just removing the "kernel=kernel_wolfson.img" line from /boot/config.txt

The Wolfson-patched sources I used to build it, with .config, ready to build.

You don't need them, I just want to make them available.

Hi Patrick, Ragnar and Geordie et al,

I am really pleased to see the developments you have made on your compressed image files - nice work !

The reason we helped create the download Wolfson image (with help from the guys at Wolfson) in the first place was to provide you with a simple way of obtaining one self contained image that had everything needed to get you up and running with the Wolfson card.

We are currently working with the developers at Wolfson and the RPI Foundation to get the drivers uploaded into the official Raspbian Kernel.

This download image is only ever intended to be a temporary measure, and we will be removing this image as soon as the Wolfson drivers are embedded into the official Raspbian kernel. Once complete, you will only need to do an "apt-get upgrade" to download the kernel drivers for this audio card.

We are expecting this work to be completed within the coming weeks and I will update this thread again once this is completed and provide instructions on how to update your standard Raspbian builds to install the new drivers and additional software needed to run the Wolfson audio card.

Hope this helps address any queries on support from e14 and Wolfson.

Andy

Thanks Andy, that's good news.

And Ragnar - thanks for all your efforts. Hope you feel better soon.
