DRA829J: DFS / DFVS : lower the DDR frequency

Geoffrey Ficara

Part Number: DRA829J

Hi, 

Related to this E2E : https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1584586/dra829v-cpu-cooling-using-dfs-in-linux?tisearch=e2e-sitesearch&keymatch=DRA829%20DFS# I am wondering if it is possible to also reduce the DDR frequency as the MPU frequency goes down to further reduce the power consumption of the board? 

Regards

Geoffrey

    Hello Geoffrey,

    No we do not have a way to bring down DDR frequency runtime through DVFS/DFS framework. All the DDR related configs are done one time at boot time in the R5 SPL. There are no DDR drivers in Linux.
