I'm running a BF607 with a 512 Mb LPDDR (Micron MT46H32M16LFBF-5 IT:C). I would like to slow the memory down to ~32MHz for power and EMI reasons. It runs great at 122MHz but won't run at all below 82MHz.
Attached are two custom board support files I'm using to test; one that runs great at 122MHz and one that does not work at all at 61MHz. The register values came from a version of "Blackfin DMC Calculation Release.xlsx" that I have modified for the BF60x with LPDDR. XTAL frequency is 16.384MHz for reference.
Have I made an error in the settings? Is there any reason the controller or the LPDDR itself cannot be run slower?
