    Audio Driver (with bounty!)

    And after two days hunting the next bug, there is again progress. I can now get the same bubbles from vizdapm (or/sys/kernel/debug/asoc/omap5-uevm/401f1000.aess/dapm/) as by Risca. Well, the bug was a missing translation from old platform devices to component drivers which did lead to a...

    Some progress after another handful of testing hours: the mcbsp widgets are now defined. Will become part of the pending letux-6.2.0 release after some code consolidation. But I still do not have the aess bubble picture as with 3.15. Next bug to trace down. Sadly there are no error messages... A...

    You could also add something to /etc/network/interfaces to set a fixed MAC or IP address.

    Yes, that is a little unfortunate with the Linux development model which finally wants to see a cleaned up set pf patches which does not favour collaboration on a single feature. This means that it is not the "pile up changes by everyone even if they undo something" model, but involves rebasing...

    Fine! I just wondered because you asked about the code checkout location because it is mentioned there every now and then, but not in a special thread. Indeed, the last "public" update was here: https://lists.goldelico.com/pipermail/letux-kernel/2023-January/008404.html in the CHANGES. Well, I...

    Generally: https://github.com/goldelico/letux-kernel You should also subscribe to the Letux kernel mailing list (https://lists.goldelico.com/mailman/listinfo.cgi/letux-kernel) to receive notifications about updates. There are also pre-built binaries: http://download.goldelico.com/letux-kernel/...

    Yes indeed... Well spotted! root@letux:~# amixer --help Usage: amixer <options> [command] Available options: -h,--help this help -c,--card N select the card -D,--device N select the device, default 'default' ... unfortunately, fixing this doesn't improve anything audible...

    Other news: I found code fragments that I had originally marked (or forgotten) as "FIXME" while converting them from a very old Linux to the latest. They seem to be necessary for operation, and their absence might have side effects, like the missing bubbles in the image. So I'm digging into...

    I had already checked the available amixer settings and they are almost identical (just different where minor features were added). But I have looked into the upstream code and there seems to be an explanation why I see some double-arrows in my root.png...

    Are you interested in a new Pandora LCD cable?

    Yes, but still faster than doing everything with 0402 and 0603 SMD by hand :) The machine was still faster than me with printing the solder paste and adding the display connectors.... And don't forget the time it takes to set up the fast machines for a handful of devices. For short runs, it's a...

    Yes, if you can provide an SD card image I can try to run on a different Pandora.

    Have run the script and something has changed, but they are partially still far away from being equivalent. Differences: I do not see any green bubble the aess picture is still very small in root, there are double links Most likely this has something to do with the dynamic setup of DAI links...

    Are you interested in a new Pandora LCD cable?

    In fact they are already done and shipped to ED... Here are some photos from the production process. And a video is here:

    Cool! I started the PandaES with the letux 6.2-rc6 kernel and found the required files /sys/kernel/debug/asoc/PandaBoardES/twl6040-codec/dapm and /sys/kernel/debug/asoc/PandaBoardES/401f1000.aess/dapm. A wget for the script and an apt-get for the dot command helped me to get three PNG files :)...

    Hm. The driver could still be ok: https://bugzilla.kernel.org/show_bug.cgi?id=195811#c3 Which means that audio routing is not set up properly for 'OMAP ABE Media LP'. Here is a more OMAP5 specific discussion about a similar error message...

    Did some first tests. The amixer settings work, but I still just get: root@letux:~# aplay -Dplughw:0,5 /usr/share/sounds/alsa/Front_Center.wav [17875.842864] OMAP ABE Media LP: ASoC: no backend DAIs enabled for OMAP ABE Media LP on channel 5. The others can not be opened. This means there is...

    Great!!! I may find some time over the weekend for my (modern) AESS setup and some part of the issues may be the amixer settings, for example 'AUDUL Media'. At least I may find another starting point for debugging. Thanks for this puzzle piece.

    Micro Pyra news from the.. dragons mouth

    Well, it is only clear from a 20 minutes test that it runs 20% faster for some multi-threaded prime number calculations (well, on 4 cores at 2 GHz instead of 2 cores at 1.5GHz so in fact each single core is much slower). From the data collected so far I would not yet draw any conlusion which one...

    Well, there are already some tiny musicians inside :) They are called Electrons and Bits... Joke put aside, there is again a minor progress. I did compare the v3.15 based setup with my latest build, both on the PandaBoard ES (which has the same audio architecture as the OMAP5) and found another...
