AM335x DDR3 Frequency Scaling

Jithin Shyam

Dear Team,

In Beaglebone Black Processor Rev is 2.0 and above, and DDR3 Clock is set to 400MHz, for Rev 1.0 DDR3 clock is set to 303MHz, whether we can use 400MHz DDR3 Clock for Rev 1.0 chipset ?

Hi,
Are you using any EVM board or custom ?
SDK version details ?

As per the AM335x silica rev data sheets, not able to see any DDR clock speed related problems.

Dear Team,

We have our own hardware, only in beaglebone black we found DDR clock is set to 400MHz, all other EVM like SK-EVM, Bone White, DDR3 Clock is set to 303MHz, whether 400MHz is for experimental?
