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 2015-05-22 12:44 GMT+02:00 Winfried Ritsch <rit...@iem.at>: > just to add my experience. > > > > I am now running some Olimex A10-Lime with amplifier boards on a sound > installation and it works quite stable. > > > > Test-board see: > > > > http://puredata.info/docs/embedded/olinuxino/algo_a10board_05_cut.jpg/view > > > > I compiled jackd myself excluding dbus service so it worked, but did not > get > > a better performance so I use pd with ALSA directly. > > > > mfg > > winfried > > > > > > Am Mittwoch, 13.
