    CMOS registers

    CookieMeister

      Hi everyone,

       

      I am aware that the Edison exposes an RTC via the PMIC, x86 RTC chips usually have an extra space (114 bytes) dedicated to BIOS configuration and such.

       

      Linux does indeed expose a file (/dev/nvram) which seems to map to CMOS registers. I have tried writting to /dev/nvram, but it seems that those bytes are reset on reboot.

       

      Does the Edison's RTC have CMOS registers, and if it is the case, how can I use them?

       

      Regards.
