Connect pulldown resistors for DDR0_RESET0_n (DDR_RESET#), DDR0_CKE0 (DDR_CKE (optional)) and pullup resistor for DDR0_ALERT_n (DDR_ALERTn) close to memory (DDR4) device. Provide pulldown resistor for DDR4 device TEN (test enable) close to memory (DDR4) device. For implementation and resistor value, see the device-specific SK.
Connect recommended resistors for DDR0_CAL0 (close to processor) and ZQn (n=0..1, close to memory (DDR4) device). For recommended connection, resistor value and tolerance, see the device-specific data sheet and AM62x DDR Board Design and Layout Guidelines.
