AM335x Power mode

UNA

Hi,

I would like to provide fixed voltage,at VDD_CORE=1.1V, VDD_MPU=1.26V, VDD_DDR=1.8V, VDDSHV1～6=3.3V:TURBO

In that case, Can I use Sleep mode(Deepsleep, stanby, RTC-Only)?

Or I must use OPP50 voltage ?

 

Regards,

Chi

    Chi, you can support the sleep modes without implementing OPP50.  You really would be just implementing frequency scaling. 

    Be aware that power numbers will be different than what is published for each mode.  Also, our linux kernel follows the definition of each mode and utilizes DVFS, so you would need to change the kernel significantly if you are using linux.
