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?
