Hello,
We are working on a future board based on OSD32MP1, so we are currently testing it on the dev board OSD32MP1-BRK. We have used the image “OSD32MP1-BRK OpenSTLinux | Version: 2.0 | September 23, 2020” for our first test. When we do the following command :
# echo mem > /sys/power/state
we notice a drop in power consumption, in the same way as when we do the following command: # echo mem > /sys/power/state
# shutdown -h 0
When using the image “OSD32MP1-BRK Octavo Systems Debian 10 | Version: Release 1.2 | May 08, 2020” the following command does not work:
# echo mem > /sys/power/state
For the “shutdown” command, it works but there is no change in the power consumption.
Is there any driver or modification to make to the Debian image to have the same power management functionality as on the openSTLinux image?

Arthur,
The low power modes were not supported in OpenSTLinux V1.0, which is what was used to develop the Debian image. They will be supported in the next release of Debian as we plan to upgrade to Kernel 5.10 with OpenSTLinux v3.0.
Best,
Neeraj
