Certains parts support different levels of idle, such as DeepSleep0 or standby, which allow additional wake-up sources to be used with less wake latency at the expense of less power savings. I will try the 3. Ethernet connection get lost, ifdown -a and ifup -a helps to re-establish it, but without it wathdog gets triggered:. The power management features enabled on AMx are as follows:.

Generally the most cpuidle-am33xxx configuration is to have an internal pull-down and GPIO mode set which gives minimal leakage. Dec 3, The LCPD release supports mem sleep and standby sleep.
Note that if the firmware binary is built into the kernel it cannot be loaded using the methods above and will be automatically loaded during boot.
For technical support please post your questions at http: In reply to Gordon Li: Certains parts support different levels of idle, such as DeepSleep0 or standby, which allow additional wake-up sources to be used with less wake latency at the expense of less power savings. In all scale data provided by TI the i2c bus speed is specified as 0x, which corresponds to kHz.
In reply to Gordon Li:.
Is it possible for you to switch to the 3. OPP is a pair of voltage frequency value. One being that are able to recover the link.
This page covers power topics for the v4. Mounted root ext4 filesystem readonly on device Also the sequence that causes that problem does not seem to apply here. This driver exposes an API to be used by the PM code to provide board and SoC specific data from the kernel to the CM3 firmware, request certain power state transitions, and query the status of any previous power state transitions performed by the CM3 firmware.
To implement Dynamic Frequency Scaling DFSthe voltages in the table can be changed to the same fixed value to avoid any voltage scaling from taking place if the system has been designed to use a single voltage.

At any point, triggering one of the aforementioned wake-up sources will cause the kernel to resume and the board to exit DeepSleep0. This page has been accessed 11, times.
It is also possible to enter standby sleep with the possibility to use additional wake sources and have a faster resume time while using slightly more power.
After these two bytes are the message blocks which can have a variable length. This is handled by the wakeup M3 processor and gets defined inside the device node within the board device tree file.
Therefore, it is not possible to encode a range of voltage representing an OPP voltage. Views Read View source View history.

The Tracer is not enabled in the 3. The following sections cover the specifics of using the aforementioned power management techniques for each part that is supported by this release. The DS pull is enabled which uses a pull down by default and DS off mode is used which outputs a low by default.

Here is the bootlog: Does anybody have any clue? Is there just one ethernet interface on the AMx?

The i2c sequences needed to scale voltage vary from board to board and are dependent on which PMIC is in use, so we use board specific binaries that are passed to the CM3 firmware to define the sequences needed during the sleep and wake paths.
The clock information and the operating-points table need to be added as given in the example below.
