Hi,
I want to use the rtc wake up function on coreboot and Linux on ASUS
M2V MX-SE. I used rtcwake command (ver 2.19) from
ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/ to automatically
wake up the machine after an S3 sleep. This works well on manufactured
ASUS bios. But with coreboot, it reports an error, "open device
/sys/class/rtc/rtc0/device/power/wakeup failed." It seems the command
try to find /dev/rtc0 but failed. And I checked that device manually;
it does not exist.
Anyone knows why this happened and how to fix it? Thanks!
Regards,
Jiang
