Hello, in at91_pmc_attach you're assume a certain main clock frequency. Isn't it reasonable to read this value from the main clock frequency register if it is available? I mean something like uint32_t mcfr = RD4(pmc_softc, CKGR_MCFR); if (mcfr & CKGR_MCFR_MAINRDY) at91_pmc_init_clock(pmc_softc, (mcfr & CKGR_MCFR_MAINF_MASK) * 32768 / 16); else /* fallback or error */ Björn
