If governors like ondemand is used, OPP change happens automatically based on the system load. More information can be found in the device specific usage sections below. This is dependent on which device is in use. Trademarks Privacy Policy Terms of Use. RTC-Only mode does not maintain DDR context so placing a board into RTC-only mode allows for very low power consumption after which a supported wake source will cause a cold boot.

AM335x + SMSC 9303 ethernet connection loss

The voltage source needs to be hooked to the cpu0 node. Link is Up – Unsupported update phy. The offsets to the sleep and wake are counted from the first byte after the header starting at zero and point to the first of the two bytes in little-endian order that specify the bus speed in kHz. Jul 28, By default, cpufreq, the cpufreq-cpu0 driver, and all of the standard governors are enabled with the ondemand governor selected as the default governor.

Each device will have it’s own unique voltage for given OPP. This is handled by the wakeup M3 processor and gets defined inside the device node within the board device tree file. This can be accomplished by defining a pinctrl state for unused pins and then assigning it directly the the pinctrl node itself in the board device tree so the state is configured during boot even though there is no specific driver for these pins:. Hence only MPU is suspended and resumed currently.

Dynamic voltage and frequency scaling, or DVFS as it is commonly known, is the ability of a part to modify both the voltage and frequency it cpuidle-qm33xx at based on need, user preference, or other factors. The CM3 firmware is needed for all idle low power modes on amx and amx and for cpuidle on amx.

Driver cpuidle-am33cx requests probe deferral. Jul 28, 3: The LCPD release supports mem sleep and standby sleep. Here is the bootlog: I’ve tried the 3.

In all scale data provided by TI the i2c bus speed is specified as 0x, which corresponds to kHz. The following wake sources are supported from DeepSleep0.

This is usually due to clocks that have not properly been shut off within the PER powerdomain. The DS pull is enabled which uses a pull down by default and DS off mode is used which outputs a low by default. You have to run “ipdown eth0” cpiudle-am33xx.0 then “ipup eth0” to bring the ethenet connection back. Volume was not properly unmounted. In reply to Schuyler Patton:.

In cpuidle-am3xx.0 to Gordon Li: Typically a device defines it’s pinctrl state for normal operation:.

Each binary file contains a small header with a magic number and cpuidld-am33xx.0 to the sleep wand wake sections and then the sleep and wake sections themsevles which consist of two bytes to specify the i2c bus speed for the operation and then blocks of bytes that specify the message. I will try the 3. RTC-Only mode supports the same wake sources, however DDR context is not maintained so a wake event causes a cold boot. However, in a case where there are external pull-ups connected to the cppuidle-am33xx.0 like for I2C lines it makes more sense to disable the pull on the pin.

To enter standby sleep, enter the following at the command line:. Content on this site may contain or be cpudile-am33xx to specific guidelines or limitations on use. Jul 24, 2: The required pinctrl states will differ from board to board; configuration of each pin is dependent on the specific use of the pin and what it is connected to.

TI cpufreq driver uses efuse information to scale the OPP data faailed on silicon characteristics. Starting Lighttpd Web Server: Ethernet connection get lost, ifdown -a and ifup -a helps to re-establish it, but without it wathdog gets triggered:
