It depends which Debian you're using on ARM. If Debian Wheezy, you get
an old 'pre-ARM Pd' from repository, with troubles like subnormals. If
Debian Jessie, you should get a recent enough version that works well.
There's also a way to build Jessie's Pd on Wheezy, described by

Re: [PD] olimex board

2015-05-31 Thread Raphaël Ilias
Hello,

Updating this thread about Olimex's OlinuXino board (A20-LIME  A20-LIME2)
I still get the following error (in fact the console gets filled with
dozens of them in a few seconds) :

ALSA output error (restart failed): Broken pipe

And the all DSP gets stuck, it is not computed anymore (i.e. [env~]
doesn't output anymore). I tried to make an abstraction to detect that dsp
isn't active and restart it (;pd dsp 0, then ;pd dsp 1 -- the DSP
button stays ticked).

This error appears at every startup of pd, and then randomly, I think
mostly when opening new patcher window or on CPU load peaks. In general,
pd's gui is quite slow (maybe normal on such board), and - don't know if
this is related - sometimes Xorg crashes (I'm using the precooked debian
distribution by Olimex)

I remember to read on this list that Raspberry Pi users should use a
patched version of vanilla for ARM processors, isn't it ? (And Julian also
adviced me to avoid pd-extended)

I think I'll give a try, but is there a little step-by-step howto to
learn how to install this version on a debian ?

Any help much appreciated !

cheers,

Raphaël

That patched version had a fix for denormal numbers on ARM, but the
fix was included in vanilla Pd soon after. If you use latest vanilla
Pd from Miller's site, chances are best that it will work with an ARM
board. On Raspberry Pi 2 at least it works well for me, but it is
still easy to mess things up: a short current consumption peak may
cause a power brown out which in turn shoots the usb audio card.
Therefore I got used to handle RPi with more care than a robust
laptop: load Pd, wait till it has everything initialized, then turn
dsp on, then load a cpu intensive patch.


 I think I'll give a try, but is there a little step-by-step howto to learn
 how to install this version on a debian ?

 yes, this seems to work... but a bit randomly.

 however, it needs to be turned off and back on to work
 in the main patch, i added something like

 [loadbang]

 [delay 5000]
  |
 [t b b]

  |[; pd dsp 0 (
  |
 [delay 100]

 [; pd dsp 1 (

 i always have the error messages on startup, but then it's ok

 however, audio/dsp sometimes gets stuck when opening other patches
 i'll try to make a sort of watchdog that monitors when audio isn't
 computed anymore (i.e. [env~] doesn't output values anymore...)

 can you try to stop the audio processing, open the patch, and start dsp
 after the patch is loaded?

 i guess the patch loading need to much cpu so audio can not be computed
 in the same time.

Hi Raphaël,

Personally never got to the bottom of that error on Debian with pd-extended

Would recommend jumping to vanilla - most libs are available in the repo's.

Re: [PD] olimex board

2015-05-13 Thread Julian Brooks
Project sounds good, like to hear/see it.

Installation of libs is easy

search available libs in debian repo
sudo apt-cache search pd-*
(there's probably a better way of searching that doesn't bring up so much
cruft - they're in there, just scroll up)

then
sudo apt-get install pd-whatever

and you should be ready to go.

There are some (bit out of date) lists of PdE objects floating around
online and the help files from most objects tell you what lib they're part
of.

Very likely that you'd get Jack running with recent vanilla from repo's too.

Completely understand you not wanting to change such a fundamental
component at this late stage. I spent several months, on and off,
attempting to sort that error - it was annoying.

Good luck with it all,

Julian

 About the project :
 the idea is to have an autonomous system with a tiny computer running

 On the hardware it's quite fine : i get input/output sound, and the board

 in the microphone because the wifi dongle was too close, so i got some

 Hi Raphaël,

 Personally never got to the bottom of that error on Debian with
 pd-extended 0.43.

 Would recommend jumping to vanilla - most libs are available in the repo's.

 Hope that helps.

 Sounds an interesting project, be keen to hear how you get on.

 Regards,

 Julian

 Hi !

 Just to inform you that I'm currently experimenting with Olimex's
 development boards, this might interest some people here (i am not doing
 any advertising at all) who are into mobile puredata

 the set-up i use consists of
 - Olimex's A20-OLinuXino-LIME board (dual core Cortex-A7)
 - with their own Debian distribution
 - cheap USB audio interface : Terratec Aureon Dual USB
 - pd-extended 0.43-4
 - patching through VNC (and through Wi-Fi)

 And it works.
 ..not as fast as on my laptop, of course, but I can run patches ok.
 yet, the GUI is indeed quite slow (especially opening a patch)

 However, I have a few troubles, but it might not be the right place to
 ask...
 I am newbie to debian, so I couldn't setup jack at all. I'm using alsa
 but I get the error at startup :
 ALSA output error (restart failed): Broken pipe
 (and also sometimes when opening patche, I get a bunch of these and DSP
 get stuck, i need to turn OFF and ON again pd's DSP to get audio back.)

 Searching the archive, I saw that some people got the same problem and
 resolved it by suspending/de-installing pulseaudio.
 But it seems that pulseaudio isn't installed here.
 Maybe someone has got a clue, where to search...? (i know this is very
 specific problem !)

 all best,

 Raphaël

can you try to stop the audio processing, open the patch, and start dsp after 
the patch is loaded?

i guess the patch loading need to much cpu so audio can not be computed in the 
same time.
