The AM6254 DDRSS0 signals in the ALW package that would normally connect to an external SDRAM were connected directly to an integrated LPDDR4 SDRAM in the AM625SIP processor, and the pins associated with these signals were reassigned to different power or signal functions.
Refer Pin Attributes and Signal Descriptions section of the device-specific data sheet (AM625SIP – AM6254 Sitara™ Processor with Integrated LPDDR4 SDRAM).
