nick76

hello,
System. ubuntu 16.04..
I've got the error..
[ 1226.207054] rk3x-i2c ff160000.i2c: timeout, ipd: 0x10, state: 1
[ 1226.208047] cpu cpu0: _set_opp_voltage: failed to set voltage (1125000 1125000 1125000 mV): -110
[ 1226.209343] cpufreq: __target_index: Failed to change cpu frequency: -110
why does it happen?

Regards,
Nick

Hi @nick76, from your log, it seems that the RK805 (PMU) is having trouble in i2c communication,
which then is unable to provide the specific regulator voltage for cpu0.

Is this error always happening? Could you try the latest 18.04 firmware?
