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).<br><br></div>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)<br><br></div>I remember to read on this list that Raspberry Pi users should use a patched version of vanilla for ARM processors, isn't it ?
