Linux/AM3356: LPDDR power management support

rperezti

Part Number: AM3356

Tool/software: Linux

We are building an AM3356 based system with TPS65910AA1RSLR PMIC and Micron MT46H128M16LFDD-48 LPDDR. Our code will be based on Linux Processor SDK v4.03 and we need to add LPDDR self-refresh entry and exit support for Linux Standby and MEM (deepleep0) states. Do TI patches exist for adding LPDDR support to the latest SDK? Please help guide us through the process of enabling this support.

Hi Ruben,

Unfortunately there are no official TI patches maintained since we never built a platform with AM335x + LPDDR to run nightly regressions against.

Section 7.3.3.12 of the TRM does have the necessary details.

Let me check on the team if is more information available to share.

Regards,
Mike

Hi Ruben,

Apologies for the long delay. We do not have an official set of patches, however the procedure outlines in the TRM is correct.

Regards,
Mike
