I am not using OTG (Only host USB's) in the PCB I connected OTG_VBUS to GND. Is this problematic? I saw that it should be left open but not sure if it is connected internally

I want to use a SIP with ST32MP153 and it uses PC13 to PMIC wakeup, PC1 is used for MDC so I'm left with only PI8 so can't use active tamper.I sit possible to use Ethernet without MDC so I can use PC1 for active tamper with PI8?

Is there any application note for tamper pins? Which one of the pins is the active tamper?

Hi Patrick,I'm using the 257 pins package of the STM32MP153 with Ethernet.So PC1 is used for ETH_MDC.PI8 is not available because of the package.Does this means I can't use active tamper?Regards,Ofer

Is MDC mandatory for Ethernet?

I'm using one 16 bit DDR3L chip with STM32MP153 MPU. My PCB has 16 layers so there is enough routing space. Is it better to use series termination which will increase the distance between MPU and DDR or without termination and short connections?
