R17.1 powerconfig issue

Hi,

I am in the process of migrating my WP76xx device from R16.1 to R17.1.

I have noticed that the boot sequence of R17.1 prints this error:

Starting powerconfig for mdm9607: sh: write error: Invalid argument

It seems the error is due to the following line in /etc/init.d/power_config

echo "1 800000:86" > /sys/devices/system/cpu/cpufreq/interactive/target_loads

Because this fails, the remainder of the power_config script is not run.

As such, I’m concerned that the modem is not having it’s power configuration set correctly and therefore consuming more power than it otherwise could.

if you remove that line, will it have lower power consumpion?

Removing that linen did not reduce power consumption. Also by removing that line, a line further down in the bash script then failed:

/etc/rcS.d/S50power_config: line 55: /sys/module/lpm_levels/parameters/sleep_disabled: No such file or directory

I also removed that line and still no power consumption decrease

When did your module consume more power in fw r17?

Sleep mode?

Data transfer?
