Hi, I'm trying to reproduce using "src/sys/KB920X arm". So far the platform doesn't boot, because recent commits removed one ore more of these clocks: sc->sc_iclk = at91_pmc_clock_ref("udc_clk"); sc->sc_fclk = at91_pmc_clock_ref("udpck"); So I get a crash at a NULL pointer when trying to access one of these clocks. How to fix this? I simply added a NULL check. Now the platform hangs when setting up the OHCI: sys/dev/usb/controller/ohci_atmelarm.c + printf("CLOCK ON\n"); at91_pmc_clock_enable(sc->iclk); at91_pmc_clock_enable(sc->fclk); bus_space_write_4(sc->sc_ohci.sc_io_tag, sc->sc_ohci.sc_io_hdl, OHCI_CONTROL, 0); + printf("INIT\n"); I see the clock ON printout, and then nothing more! Not sure if this is caused by IRQ's hanging or not. Andrew Turner: Can you fix these issues so that I can reproduce? --HPS
