AM625: DDR4 Configuration PIN

Part Number: AM625
Other Parts Discussed in Thread: SK-AM62

Dear Experts,

I'm finding the clarification regarding the PIN marked as "DDRSS_SDRAM_IDX 15"in the attached image. While generating the dtsi file for a 2GB DDR4 memory configuration, it appears that this particular PIN is not utilized in the default TI dtsi files for the actual scenario(SK-AM62).

Just give clarity about this PIN configuration.

Ravi, you are correct, this is not used by the driver currently. This was recently added to be utilized later. It is not a PIN, but rather intended for the SDRAM_IDX parameter in V2A_CTL_REG. This value changes depending on SDRAM density.

James
