Hello,
I am trying to use rtcwake command to make BBB wireless board (kernel 4.4.113 ti) into sleep mode in order to save power for a period of time.
However, the command “rtcwake -m mem -s 10” returns “rtcwake: write error” after the board wakes error. I am worried this error may cause some problems.
Does anyone have any idea on how the error happens and how to fix it?
Thanks,
Chen
