Hello,
Please see the Userspace command directly above where you circled.
In newer SDK, the qos_latency is the contrstraint sent to the DM firmware to determine which low power mode to enter.

Hello,
For more details about the latency constraint, see the TISCI documentation: https://downloads.ti.com/tisci/esd/latest/2_tisci_msgs/pm/lpm.html#tisci-msg-lpm-set-latency-constraint
The number written to this SYSFS entry will determine which low power mode to enter. 100 can be used for MCU Only mode.
Thanks,

Hello,
I don't really understand how to configure the MCU ONLY in
Do I need to modify the code in the SDK of 11.00.09.04 to implement the MCU only function?
If you want to modify the source code of the SDK, please ask whether the SDK version 10.00.07.04 we use supports modifying the source code to implement MCU ONLY
Hello,
As stated in the Linux SDK documentation, the only command before suspending is
echo 100 > /sys/devices/system/cpu/cpu0/power/pm_qos_resume_latency_us
There are no other changes required.
Thanks,
Anshu
