    How would you put the MTCDP-H5 processor in to sleep mode, with a wake up on USB data?

    Hi Campbell,

    Try to issue the following command:

    echo standby > /sys/power/state <–Put the CDP in standby mode.

    Then plug in a USB thumb drive into the USB host port. The CDP should come out the standby mode.

    Thanks,

    BT

    Hi everyone,

    Is it possible to put the MTCDP-H5 processor in to sleep mode, but with a wake up on RS-232 data?

    Hi Andrey,

    If you have a process that reading the data from the serial port on the CDP device running. Try to issue the following commands:

    1. echo enabled > /sys/devices/platform/atmel_usart.2/tty/ttyS2/power/wakeup

    *Enable wakeup on ttyS2 port

    2. echo standby > /sys/power/state

    *Put the CDP in standby mode

    Regards,

    BT
