[beagleboard] Re: Maxim Codec and BBB a different way.

[J dog]

   Many including myself don't understand all  the complexity's of the way 
the alsa-soc is developed.  And only a few engineers really have the grasp 
of it.   Its so complex that T.I. themselves said mixing I2C and I2S into 
the same code bundle makes it unnecessarily hard to develop a routine for 
each soc board and each codec.   Here I will state some of the things as I 
understand happen in alsa-soc.
Alsa states,  there should a definition for each platform,  a definition 
for each codec, and oddly something called the machine which is how they 
intercommunicate I believe.
What this means is for each platform, such as  A beaglebone black and a 
 beaglebone xm, the code could be different.  On top of that you then have 
to have definitions for each codec.   So just because you have definitions 
for a codec from a codec maker,  it doesn't mean your gonna compile that 
into the kernel and walla!  your platform is now talking to the codec, its 
just not that simple.  All this was done to combine i2c and i2s specifics 
for each codec / platform to work from one package.  
But after looking at this and realizing I was on the short end of a long 
stick and finding a programmer that could even understand this stuff,  It 
became evident that I2C was the villain like T.I. said.   Looking at the 
disadvantages besides the complexity,  what happens in this prescribed 
platform, codec, machine we find
I2C being a timed command and response protocol uses wires 
completely different than i2s, and even a different clock. 
I2S is only audio, it knows nothing but sending and receiving audio 
packets, it doesn't care to whom and whatever codec is on the other end 
and as long as it works with the same timings should work just fine. What 
happens if a I2C command hangs in the middle of the routine to send I2S 
signals?.   audio drops and possibly worse. A badly coded alsa-soc package 
can play hell not only on audio, but may cause kernel dumps and who knows 
what else.
I2S routines should be free from any hindrance,  let the kernel handle this 
because its a very timing critical task. 
I2C commands though should occur from user space, they aren't so timing 
critical and if from user space an i2c send / response sequence hangs, the 
kernel / i2s routines probably wont even care. 
I2C from user space has the advantage of enhanced command error checking 
and being able to be written in many languages that have access to i2c 
calls, such as python, c++, nodejs and golang. 

In this regard, an i2s driver with configurable parameters could be written 
for every soc platform, and only once!  And an i2c routine can be universal 
on all soc-platforms if the hooks to the actual pins are abstracted.I 
will be presenting this thesis to the ALSA consortium at a future date.

[beagleboard] Maxim Codec and BBB a different way.

[J dog]

I am updating our project page for an advanced remotely controlled audio 
system using the BBB and a Maxim Codec 98089.   We use a different method 
for alsa-soc than most. Our DTB driver only uses I2S and no I2C control 
mechanism is included in it. We think this makes the I2S routine cleaner 
and less error prone.  We then use FTDI over USB to send our commands to 
the codec.  We will be releasing the driver to the BBB community in a few 
days.  But you can learn a lot of what we are doing now at our project 
page. 
Perhaps as other developers learn more, alsa-soc may one day only need 
platform specifics and allow any I2S codec to be used and the only thing 
one needs to change are routines that call I2C commands or in our example 
FTDI commands from user space.

[beagleboard] Re: Beaglebone Black + Audio codec TLV320AIC3106

[J dog]

Something of this nature should work on the command line.

amixer -c sset 'Left Line Mixer LLOUT' on # Line out Left enable
amixer -c  sset 'Right Line Mixer RLOUT' on# Line out Right 
enable
amixer -c  sset 'Line DAC' 90  # Adjust Line out 
volume

This is a guess.  But if you want to know more check out this page.

Probably something of this nature will work. 

amixer -c  sset 'Left HP Mixer DACL1' off  # HP Left route 
disable
amixer -c  sset 'Right HP Mixer DACR1' off # HP Right route 
disable
amixer -c  sset 'Left Line Mixer DACL1' on # Line out Left

amixer -c  sset 'Right Line Mixer DACR1' on# Line out Right

amixer -c  sset 'Line DAC' 90  # Adjust Line out

[beagleboard] Re: What? Linux development on windows... and arm support

[J dog]

Seems microsoft is trying to stay relevant?  
Windows 10 is no longer just an operating system for 32 and 64-bit PCs. 
In recognizing there are many other OS's out there,  Its Microsoft's goal 
to allow developers to create Universal apps that will run not only on PCs, 
but on Arm based phones and tablets, Windows 10 for IoT devices and Xbox as 
well. 
 A new version of windows Phone will be available and If you know what Windows 
RT 

 was, 
then don't worry, because it's nothing like that, and major changes are 
coming.

Re: [beagleboard] Super Advanced audio / media system using Beaglebone Black

[J dog]

Hey Robert,  I have the alsa-soc / Device Tree source for the maxim 98089 
codec on the BBB if you want to add it to the beagle source tree.   I'm 
giving it to the BBB community.  This is a I2S only device driver. User 
must use a userspace I2C routine or our FTDI over usb routine to send it 
commands. The chip / development board may be around for a while as its the 
codec used in many Google Chrome books.Let me know if you want it.

[beagleboard] Pehaps the AM572X is actually the OMAP5?

[J dog]

Am I wrong or is it no coincidence the AM572X has much of the same features 
(CPU and GPU to name a few)  as the long awaited and dropped OMAP 5?.  And 
it has been stated it will fully support Android which was going to be the 
OMAP 5's forte.   Not a bad thing,  cant wait to see what folks can make it 
do.

[beagleboard] Might the AM572X be the OMAP 5 in disguise?

[J dog]

Looks like to me the AM572X has a lot of the same CPU and GPU components as 
the Maligned and dropped OMAP 5.  As it says Android is fully supported 
also which was going to be OMAP 5's forte.Not a bad thing,  I'm glad 
T.I. is keeping it around even if its under a different guise.

Re: [beagleboard] Super Advanced audio / media system using Beaglebone Black

[J dog]

Hey Jason,
I am working on a release.  Initially I will just supply a image for sd 
card, it has compiled system and source both on it.   Due to fact some may 
not want to pay for the Maxim evaluation board, 
  
http://www.digikey.com/product-detail/en/maxim-integrated/MAX98089EVKIT%23WLP/MAX98089EVKIT%23WLP-ND/2708761
 I'm going to work on a release that simply makes use of  linux alsa amixer 
oriented audio so usb and other generic alsa devices can play music. 

It will be  a few days. Before I can do this.The alsa-soc platform / 
machine source code will be in a different package.   This code is a bit 
revolutionary as it doesnt care about I2C communications with codec.   The 
I2C or if codec has USB FTDI capability, volume, eq controls are handled 
from user space code.   What that means is one may very well be able to use 
any codec that meets our devices ( the beagle/codec)  I2S clocks and pin 
usage assignments.   This code works great, perhaps with some extra 
capabilities added in,  gone will be the days of needing custom devicetree 
 alsa-soc platform/machine code for each particular codec.  At least on the 
am335x thats our goal.

Re: [beagleboard] Super Advanced audio / media system using Beaglebone Black

[J dog]

Thanks Robert,  we have already set up a preliminary indiegogo page,
unfortunatly one must get a project to 'trend' in order to be successful.
Hence thats part of the reason we are here and on other forums, to get a
group of followers who care to give financial, technica supportl, and of
course encouragement and advice!

heres the link, for the page...  its not live yet, but hopefully will be
soon.

Re: [beagleboard] OpenGL SGX no support for hardware renderer

[J dog]

Hey Robert,
I'm still getting the gist of the framebuffer implementation.  Can the 
system read a h.264 mpeg file and send it to the framebuffer letting the 
VR530 handle any decoding?  
What sort of performance numbers can be expected?   720p at 30 hz for 
example? any CPU Overhead numbers?

[beagleboard] Advanced BBB audio playback and streaming system.

[J dog]

We have spent the last 1.5 years creating an advanced audio system with the 
BBB.  Its able to record, stream, and playback music over wireless 
speakers.  We could use some help in getting this project off the ground. 
 It can be controlled by Windows, Mac and Android devices,  it has a built 
in hard drive and we have chromecast streaming to tv's even working.  But 
critical work needs completed before we can present it to the public. 

Comments, testers and Coders are welcome.
