I'm using the standard firmware with an OpenEmbedded filesystem on a Juno Development Platform
hello expert,
1. # echo 800000 > /scaling_setspeed
2. # cat /scaling_cur_cpufreq
# 850000
No matter scaling_governor is ondemand or userspace, this still the same.
that is i cannot fixed cpufreq at 800MHz, what is the correct operation?
thanks.
Which core are you trying on ?
The list is as follows:
A57 : 450, 800, 1100 MHz
A53 : 450, 700, 850 MHz
So if you try 800MHz on A53, it choose closer option to that which is 850MHz.
