My beaglebone xm won't do idle: | omap3_pm_off_mode_enable: Core OFF disabled due to errata i583 but it would if it could, right? That means that I can't test the wake via UART on this one? So I will try to fix the tx-pm, fold patches and then prepare another batch. And I could verify that DMA works on that omap3 :) > Regards, > > Tony Sebastian
