Hi, I wrote a very simple DSP test and I'm having some synchronization issues. http://github.com/felipec/dsp-dummy Basically: DSPNode_PutMessage (core->node, &msg, DSP_FOREVER); usleep (4000); DSPNode_GetMessage (core->node, &msg, 0); If I remove the usleep, I get: DSPNodeCreate succeeded DSPNode_run succeeded WMD_DEH_Notify: ********** DEVICE EXCEPTION ********** WMD_DEH_Notify: DSP_SYSERROR, errInfo = 0x102 WMD_DEH_Notify: ********** DEVICE EXCEPTION ********** WMD_DEH_Notify: DSP_SYSERROR, errInfo = 0x102 WMD_DEH_Notify: ********** DEVICE EXCEPTION ********** WMD_DEH_Notify: DSP_SYSERROR, errInfo = 0x102 WMD_DEH_Notify: ********** DEVICE EXCEPTION ********** WMD_DEH_Notify: DSP_SYSERROR, errInfo = 0x102 If I add it: DSPNodeCreate succeeded DSPNode_run succeeded Any ideas? -- Felipe Contreras -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
