Ok, well now let's figure out if the reset is working or not. look at arswitch_attach(): * It sets up the default methods; * it calls ar8327_attach(); * it resets the switch via arswitch_reset(); * it calls the HAL methods to set things up; * it attaches the PHYs; * it attaches said PHYs; * it starts the periodic checks via arswitch_tick(). So, I'd add some printf()s in arswitch_attach() to see where it's getting to before it calls return (ENXIO) or return (err). -a On 8 March 2014 14:41, Milan Obuch <freebsd-mips@dino.sk> wrote: > On Sat, 8 Mar 2014 14:18:46 -0800 > Adrian Chadd <adrian@freebsd.org> wrote: > >> Hi, >> >> it's a different silicon version. >> >> Try this patch.
